Do You Need a Case Packer? Manual, Semi-Auto and Robotic Compared

You can tell a lot about a plant by walking to the end of the line. The bagger runs at 90 packs a minute, beautifully, and then four people stand around a table putting bags into cartons by hand. That table is usually where the money is leaking.

Case packing is the least glamorous purchase in the building and often the fastest to pay back. But it is also where buyers overspend, because the jump from manual to robotic is not the only option.

Start with the labour math

Count the people at the end of the line and what they cost fully loaded: wage, benefits, supervision, recruitment, and the days they do not come in.

Take a line running 5,000 bags an hour into 12-bag cartons. That is roughly 417 cartons an hour, or 7 a minute. Two people can manage that by hand, and they will be tired by the end of the shift. At 24 bags per carton, it is 208 cartons an hour, and one person can keep up.

Now double the line speed. Two people become four, and four people at 7 cartons a minute is not a plan, it is a bottleneck with a backache. This is the point where automation stops being a luxury.

Level 1: manual packing, done properly

Manual is not the same as bad. Before you spend anything, fix the table: correct height, a carton former within reach, a bag chute that presents the bag the right way up, and a scale to check counts. A 600 dollar ergonomic rebuild often buys 20 percent more throughput.

Set a hard limit. When your line needs more than three people on packing, or when you start hearing about wrist and shoulder injuries, manual has stopped being cheap.

Level 2: semi-automatic

This is the sweet spot most small and mid-size plants should look at first. A semi-automatic case erector plus a manual or semi-automatic top sealer gives you one operator instead of three, at 15,000 to 30,000 dollars.

Typically 15 to 25 cartons a minute, one operator loading, machine erecting and sealing. It is forgiving, changeover is easy, and it does not need a controls engineer when something goes wrong.

What it does not do is remove the operator. If your labour cost is the whole problem, this only halves it.

Level 3: automatic

Three families, and they are not interchangeable:

Drop packers let bags fall into an erected case through a funnel. Cheap, fast, and best for flexible bags that can take a small fall. 30,000 to 60,000 dollars.

Wrap-around packers form the carton around the product from a flat blank. Excellent for cans, jars, and rigid packs, and it saves board. 60,000 to 120,000 dollars, and it locks you into one carton style.

Robotic pick and place picks bags or pouches and places them in a case or a tray. Flexible, gentle, handles multiple patterns, and 80,000 to 150,000 dollars before integration.

Which one fits your carton

Your existing carton decides more than your budget. A top-loading RSC case suits a drop packer. A wrap-around blank suits nothing else. A tray with a lid suits a robot. If your retail customer specifies the case, work backwards from that specification, not from the machine brochure.

The integration problems nobody quotes for

Accumulation. A case packer cannot take bags at a perfectly even rate, so you need a buffer between the bagger and the packer, or the bagger will stop and start all day.
Speed mismatch. Buying a 25 carton per minute packer for a line that produces 30 is how you create a permanent 20 percent loss.
Changeover. A machine that takes 40 minutes to change carton size will be run on one size forever, whether that suits your orders or not.
Floor space. Case packing needs length. Measure the room before you fall in love with the machine.

Payback, roughly

A plant replacing three packers with a semi-automatic system at 25,000 dollars: three people at 22,000 dollars fully loaded is 66,000 a year, and the machine needs one operator, so the saving is about 44,000 a year before maintenance. Payback under eight months, ignoring everything else.

At that maths, the question is not whether to automate, but why it took so long.

When not to automate

If you run short batches with frequent carton changes, if your product mix changes weekly, or if your line runs four hours a day, a semi-automatic machine plus a well-designed table is probably the correct answer. Automation rewards repetition.

If you are automating the bagging end first, our cartoning machine range covers the step between bagging and case packing, and this ROI breakdown shows how to put labour into the total cost model.

Frequently asked questions

At what volume does a case packer pay for itself?

Roughly when you need three or more people on packing, or above 15 cartons a minute sustained. Below that, semi-automatic equipment usually pays back faster with less risk.

Can one case packer handle several carton sizes?

Yes, with change parts that typically take 20 to 60 minutes. Ask to see the changeover performed, and ask what the parts cost, because a full set can run 5,000 to 15,000 dollars.

Is a robot always more flexible?

More flexible in pattern, less flexible in speed and cost. A robot placing 40 bags a minute is realistic; a drop packer at 60 is cheaper and simpler if your product can take the fall.

Do I need a carton erector too?

If you are running automatic packing, yes. Hand-erected cases at 30 a minute is not sustainable, and the erector is usually the cheapest part of the line.

Chamber Vacuum Sealer vs Thermoforming Vacuum Packer

Both machines remove air from a pack and seal it. That is where the similarity ends, and buyers who treat them as one category usually end up with the wrong machine for their volume.

The fundamental difference

A chamber vacuum sealer puts a filled pouch inside a chamber, pulls a vacuum on the whole chamber, seals the pouch, and releases. The pack is a bag.

A thermoforming vacuum packer takes two rolls of film, heats the bottom film and forms it into a tray shape, loads product into that formed cavity, vacuum seals the top film over it, and cuts the packs apart. The pack is a rigid-ish tray with a soft lid.

One machine is a batch process built around a bag. The other is a continuous process that makes its own container.

Output, honestly

A single chamber machine runs 1 to 3 cycles a minute, and every cycle has a dead time while the chamber pulls down and releases. A double chamber machine lets the operator load one side while the other seals, so you get closer to 4 to 6 cycles, but you are still batching.

A thermoforming machine runs continuously, typically 4 to 12 cycles a minute depending on pack size and film, with no chamber dead time. At the top end it is a different order of throughput, which is why it dominates in meat and cheese plants.

Cost per pack, and it is not obvious

Pouches cost money per unit. Thermoforming film costs money per square metre, and a formed tray uses more material than a flat pouch for the same product. On paper, the pouch is often cheaper for small packs.

But add labour: a chamber machine needs an operator loading bags every cycle, all day. A thermoforming line needs one operator supervising. At 3,000 packs a shift, labour usually outweighs the film difference. Do the arithmetic on your own numbers before you assume pouches are cheaper.

Where a chamber machine is the right answer

Low to medium volume, under roughly 1,500 packs a shift
Very large or very tall products that will not fit a formed cavity, such as whole hams or large cheese blocks
Liquids and wet product, where a pouch is simply easier to handle
Multiple products with no format investment – change the bag, not the mould
Small budget. A double chamber machine at 6,000 to 12,000 dollars versus a thermoformer at 30,000 and up

Where thermoforming wins

Retail presentation. The formed tray with a clear lid is the standard look in supermarkets for fresh meat, poultry, and fish
Long runs. One product, one mould, thousands of packs a day
Automation. It integrates naturally with a labeller, a metal detector, and a case packer
Consistent pack dimensions, which matters enormously for downstream automation and for retail planograms

Skin pack is a third thing

Skin packaging heats the top film until it drapes over the product and seals to the bottom film, with no air gap at all. It looks premium, it stops product moving in the pack, and it is popular for steaks, seafood, and hardware. If you want that look, you need a skin packaging machine, not a standard thermoformer, and the film is a specialist item.

Maintenance differences that show up in year two

Chamber machines are mechanically simple but work hard: the vacuum pump runs constantly, the sealing bar takes abuse, and the chamber gasket is a wear item you will replace. Budget for a pump service and two gaskets a year.

Thermoformers add moulds, forming heaters, chain or film transport, and a cutting station. More to maintain, more to clean, and the moulds are expensive to change. Ask what a second format costs before you buy, because it is often 8,000 to 20,000 dollars.

Product constraints worth checking early

Maximum product height, and how much the film can stretch over a sharp edge
Bone-in product, which needs a thicker bottom film or a barrier board
Liquids, which need a different sealing sequence and often a different machine
Frozen product, where condensation between the films ruins seals

If you are packaging meat, cheese, or ready meals, also read our guide to matching film to machine, because vacuum packs fail at the film interface far more often than at the pump. You can see both machine families in the vacuum packaging range.

Frequently asked questions

Can a chamber machine pack 5,000 units a day?

Only with multiple machines or very long shifts. A double chamber unit realistically handles 1,500 to 2,500 packs a shift. Above that, thermoforming or a continuous belt machine is the better fit.

Which gives a longer shelf life?

Similar, if the residual oxygen is the same. Thermoforming often achieves lower residual oxygen because the pack is formed and sealed in one cycle, but a good chamber machine with a deep vacuum and a clean seal is close.

Do I need a different film for each?

Yes. Pouches are pre-made laminates; thermoforming needs a formable bottom web and a sealable top web with matched sealing layers. They are not interchangeable, and buying the wrong one is an expensive mistake.

Can I run both?

Plenty of plants do: a thermoformer for the retail line and a chamber machine for bulk, samples, and odd sizes. If your volumes justify it, that is usually cheaper than trying to make one machine do everything.

Premade Pouch Machine vs VFFS: The Cost-per-Bag Math

Put two videos side by side and a premade pouch machine and a VFFS look like cousins. Both drop product into a bag, both seal, both count output on a screen. Buyers compare the two quotes, see numbers in the same range, and pick the one with the nicer bag sample.

Then the film invoices start arriving, and the two machines turn out to live in completely different economies.

The difference in one paragraph

A VFFS machine takes flat film off a roll, forms it into a tube over a shoulder, fills it from above, and seals top and bottom. You buy film by the kilo. A premade pouch machine takes bags that were printed, laminated, and sealed on the sides by a converter, picks one up, opens it, fills it, and seals the top. You buy finished bags by the thousand.

That is the whole story. Everything else follows from who makes the bag and when.

Where the money actually goes

Film and pouches are the largest line item in the comparison and the one most often left out of it. A rough working range for a printed stand-up pouch with a zipper, at retail quality, is 8 to 14 US cents per bag in moderate volumes. Roll film for the same bag size and barrier, printed, typically lands somewhere between 3 and 6 cents per bag. The gap is not small.

Run it on a real number. Say you pack 5,000 bags a day, 300 days a year. That is 1.5 million bags.

Premade pouches at 9 cents: 135,000 dollars a year in packaging material
Roll film at 3.5 cents: 52,500 dollars a year
Difference: 82,500 dollars a year

Now look at the machine quotes again. If the pouch machine is 15,000 dollars cheaper, that advantage disappears in about nine weeks of production. This is why the answer to “which machine is cheaper” is almost never the answer to “which machine costs less”.

Where premade pouches are worth every cent

Cheap is not the same as right, and there are plenty of products where roll film is the wrong choice.

Bag features you cannot form inline. Spouts, slider zippers, shaped bottoms, clear windows, matte and gloss combination printing, foil stamping. A VFFS can add a zipper, but the bag will never look like a converted pouch.
Shelf presence. If your product sits on a retail shelf next to three competitors, the pouch is a marketing asset and the film saving is irrelevant.
Heavy or awkward product. Two kilos of pet treats, chunks in sauce, hardware kits. Premade pouches arrive with a real bottom gusset that holds weight.
Low volume, many SKUs. Twenty flavours at 3,000 bags each. You cannot justify twenty printed film rolls, but you can order twenty pouch SKUs at a converter’s minimum.
No printing budget. Pouch converters will run small lots with digital print. Film printers will not.

Where roll film wins without much argument

Cost per bag at volume. Nothing beats forming the bag from film on the same machine that fills it.
Speed. Modern VFFS units run 80 to 120 bags a minute on snacks, and small sachets go far higher. Pouch machines typically sit between 30 and 60 depending on the filling system.
Warehouse space. One pallet of film rolls replaces six pallets of finished pouches. If your building is already full, this matters more than the spreadsheets suggest.
Supply chain simplicity. One film supplier, one lead time, no risk of a pouch shortage stopping the line.
Waste handling. Trim waste is continuous and easy to collect. Pouches that fail to open get thrown away whole, which stings at 9 cents each.

The comparison table, with real ranges

Factor	Premade pouch machine	VFFS
Packaging cost per bag	8 to 14 cents	3 to 6 cents
Machine price, entry	18,000 to 35,000 USD	9,000 to 25,000 USD
Machine price, high end	60,000 to 120,000 USD	35,000 to 100,000 USD
Output	30 to 60 bags per minute	60 to 120 bags per minute
Film minimum order	20,000 to 50,000 pouches per SKU	100 to 300 kg per SKU
Changeover between sizes	20 to 45 minutes, mostly gripper and format parts	10 to 30 minutes, mostly bag length and former
Bag styles	Stand-up, flat bottom, three-side seal, spout, slider	Pillow, gusset, quad seal, doypack with attachment
Best product fit	Chunky, heavy, premium, low volume	Free-flowing, high volume, cost-driven

The three-year comparison, not the purchase order

Build a simple sheet with four columns: machine and installation, packaging material over three years, labour, and expected waste. Then add one more column most buyers forget, which is the cost of a format change. A pouch machine that needs 40,000 dollars of gripper sets to move from a 200 g to a 500 g pouch is not a flexible machine, it is two machines sharing a frame.

Run the same three-year sheet for a VFFS with a zipper attachment if you are somewhere in the middle. The bag is not as handsome as a converted pouch, but it costs half as much and it opens the snack and frozen categories for you.

What usually decides it

In our experience, three things decide this comparison, in this order: the bag has to look a certain way on the shelf, the annual volume has to justify the material cost, and the product has to survive the drop into the bag. If the shelf look wins, buy the pouch machine and stop arguing about film. If volume wins, buy the VFFS and invest the difference in a better weigher, because a cheap weigher on a fast machine produces expensive waste.

And if you genuinely cannot decide, ask both suppliers for a sample test with your product and run the numbers for 1,000 finished bags, all in, including film, labour, and rejects. The answer is usually obvious once you are counting finished bags instead of reading brochures. See the pouch options in our premade pouch machine range and the roll-fed side in our VFFS machine range.

Frequently asked questions

Is a premade pouch machine cheaper to run than a VFFS?

Almost never, unless your volume is very low. The machine is simpler to change over and the bag looks better, but you are paying someone else to make the bag, and that shows up in the price per thousand.

Can a VFFS make stand-up pouches?

Yes, with a doypack or quad-seal attachment. The result is a good bag, but it will not match the print quality, shaping, or zipper options of a converted pouch.

What volume justifies a premade pouch machine?

The pouch machine becomes attractive when you need premium bag features, many SKUs at low volume each, or heavy fills. At steady volumes above roughly 3 million bags a year, the material cost gap usually pushes you to roll film.

Which is faster?

VFFS, typically. A well-set VFFS on snacks runs 80 to 120 bags a minute, while a four-station pouch machine usually lands between 30 and 60.

Servo vs Mechanical Flow Wrapper: What the Extra Money Buys

Two flow wrappers. Same frame size, same output on paper, one is 18,000 dollars and the other is 45,000. The salesperson for the cheaper one says servos are overkill. The salesperson for the expensive one says mechanical machines belong in a museum.

Both are wrong, and the difference is easier to understand once you look at what actually moves inside the machine.

How a mechanical wrapper works

One main motor turns a shaft. That shaft drives cams and linkages which move the film feed, the end sealers, and the cut-off in fixed relation to each other. Change the pack length and you swap gears or adjust a cam. Change the product and you may need to change the whole timing chain.

That sounds primitive. It is also why a mechanical wrapper made in 1998 is still running in a bakery somewhere, with the original motor.

How a servo wrapper works

Each motion has its own motor and its own program: film feed, end sealer, cut-off, infeed. A controller keeps them in sync through software rather than a cam shaft, so changing a pack length is a number on a screen, and the sealing jaws can be told to slow down for a fragile product.

That is the whole argument. Everything else in this comparison follows from it.

Where mechanical still wins

One product, one size, all year. If you run a single biscuit in a single pack, the flexibility of servos buys you nothing you will use.

A dusty or abrasive environment. Flour dust and sugar kill encoders and fans. A cam-driven machine has fewer sensitive parts to protect.

Local repair capability. A mechanical fault is usually a worn bearing, a stretched chain, or a broken spring, and a good fitter can fix it with the machine in place. A servo fault needs a laptop, a manual, and sometimes a factory password.

Budget, honestly. At 18,000 versus 45,000 dollars, the mechanical machine can be the right call for a small plant that will never change its packaging.

Where servo pays for itself

Changeover. This is the big one. A mechanical wrapper changing from a 65 mm to a 95 mm pack might take 60 to 120 minutes with tools. A servo machine recalls the recipe in five. If you change format twice a week, that alone can be 100 hours a year.

Film waste at startup. Servo film feed finds registration faster and holds it. On printed film, the difference in startup waste often runs 30 to 50 percent.

Fragile product. Independent sealing jaw motion lets you slow the jaw at the moment of contact, which matters for wafers, filled biscuits, and anything with a soft centre.

Diagnostics. A servo drive logs the fault, the position, and the load at the moment of failure. A mechanical jam gives you a broken pack and a guess.

Noise and energy. Fewer mechanical shocks, lower standing noise, and no clutch slipping all day.

The cost gap, over three years

Take a bakery running 60 packs a minute, two shifts, five days. The servo machine costs 27,000 dollars more. Set against that: 90 fewer minutes per changeover, twice a week, at 60 packs a minute, is roughly 10,800 extra packs a week of capacity, plus the film waste saving and the labour saving on setups.

For most plants at that volume, the gap closes inside two years. For a plant running one SKU on a single shift, it never closes, and that is a perfectly good reason to buy the mechanical machine.

The middle option nobody mentions

Plenty of machines are “half servo”: servo film feed and servo cut-off, but mechanical sealing jaws, or the reverse. That configuration gets you fast registration and short changeover for a much smaller price increase, and it is often the sensible answer for a first automatic line.

Ask specifically which axes are servo and which are mechanical. “Servo machine” without that breakdown is a marketing phrase.

What to check in a demo

Time an actual changeover, twice, with the operator who will do it in your plant
Watch startup waste on printed film, and count the bags thrown away
Run at 50 percent speed and listen for jaw chatter
Ask what happens when the film runs out mid-cycle, and whether the machine stops cleanly
Check whether recipes are stored by product name or by number, because operators will not remember numbers

If you are still deciding between machine architectures, our VFFS vs HFFS comparison covers the bag-forming side of the same question, and the flow wrapper range shows where the mechanical and servo models sit.

Frequently asked questions

Is a servo wrapper harder to maintain?

Not harder, different. There are fewer mechanical wear parts, but faults need diagnostic skills and a spare drive on the shelf. Budget for one spare servo drive and one backup of the program.

Can I retrofit servos to a mechanical machine?

Technically yes, practically rarely worth it. The cost of drives, controllers, and rewiring usually lands within 60 percent of a new machine, without the new frame or the warranty.

How much faster is a servo wrapper?

Peak speed is often similar. The real gain is sustained speed, because a servo machine recovers from a film splice or a product gap in seconds instead of minutes.

What about a dual lane machine instead?

Two lanes on one frame roughly doubles output for less than two machines, but changeover and jam clearing become twice the work. Choose dual lane for long runs, not for high-SKU plants.

Multihead vs Linear Weigher: Match the Weigher to the Product

The weigher is the part of a packaging line that decides whether you make money or give product away, and it is usually the part buyers understand least. Two machines, both described as “automatic weighing”, one at 8,000 dollars and one at 35,000. The cheap one is not a scam. It is a different tool for a different job.

Two ways to hit a weight

A linear weigher fills a weigh bucket until the load cell reads your target, then stops. It is sequential, so speed is limited by how fast product can fall and settle.

A multihead weigher spreads product across 10 to 16 hoppers, weighs each one, and then the computer picks the combination of hoppers that adds up closest to your target. It never fills to a weight, it selects to a weight, which is why it is faster and more accurate at the same time.

What accuracy is worth, in money

On a 100 g pack, a linear weigher typically holds plus or minus 2 to 4 g. A 14-head multihead holds plus or minus 0.5 to 1 g. That sounds like a technicality until you price the giveaway.

Say you pack 20,000 bags a day and the average overfill is 1.5 g. That is 30 kg of product given away every day. At 8 dollars a kilo, it is 240 dollars a day, roughly 72,000 dollars a year, for product nobody paid for.

A 25,000 dollar difference in weigher price looks different against that number. This is the calculation that should drive the decision, not the quote.

Where a linear weigher is genuinely enough

Large packs with wide tolerances. A 5 kg bag of potatoes or a 10 kg sack of pellets does not need half-gram accuracy, and the law does not ask for it.
Low value product. If the product costs 80 cents a kilo, giveaway is noise.
Slow lines. Below 30 packs a minute, a well-tuned linear weigher keeps up and costs a fraction.
Sticky or clumpy product. Multiheads hate product that bridges. A belt-fed linear system with a scraper handles it better.

Where only a multihead works

High speed. Above 60 packs a minute, a linear weigher physically cannot settle fast enough.
High unit value. Nuts, coffee, freeze-dried fruit, supplements. Every gram matters.
Legal net content rules with tight tolerances. Where the average must not fall below the declared weight, the multihead’s narrow spread is the cheapest compliance you can buy.
Mixed pieces. The combination principle naturally averages out piece weight variation, which a linear weigher cannot do.

The exceptions that catch people out

Sticky product. Dried fruit, glazed nuts, and anything with surface sugar will coat the hoppers and slow the feed. Look for dimpled or coated hoppers, or a belt weigher instead.

Long or large pieces. A 200 mm biscuit does not fit a standard hopper. You need a wide-mouth version, which costs more and runs slower.

Fragile product. Multiheads drop product repeatedly through the feed cone. If breakage matters, ask for a gentle feed and a lower drop height, or consider a linear system with a soft transfer.

Very small doses. Under 5 g, you are in auger or counting territory, not multihead territory.

Integration is where cheap weighers get expensive

The weigher has to talk to the bagger. That means a timing signal, a ready signal, a dump signal, and a shared clock, and it means the discharge chute must line up with the forming tube without product bouncing off the shoulder.

A 9,000 dollar weigher with no interface documentation and no one who can commission it will cost you more in engineering hours than the 12,000 dollars you saved. Ask two questions before you buy: does it come with a wiring and protocol document, and can the supplier commission it remotely with your electrician on site.

Decision table

Your situation	Sensible choice
Snacks, 80 packs per minute, tight weight law	14-head multihead
Coffee, 40 packs per minute, premium product	10-head multihead with degassing
Frozen dumplings, sticky, 45 packs per minute	Multihead with non-stick hoppers, or belt weigher
5 kg rice bags, 25 bags per minute	Linear weigher
Hardware kits, counted pieces	Counting scale, not a weigher
Powder, 1 kg, 30 bags per minute	Auger filler with check weighing

If you are sizing the whole line rather than just the weigher, read how to match machine capacity to production volume first, then look at the VFFS range for the bagger side of the pairing.

Frequently asked questions

Can a linear weigher be accurate to one gram?

On a 50 g dose with free-flowing product and a good vibratory feed, close. On a 500 g dose, no. Accuracy in absolute grams scales with the dose, so compare as a percentage before you decide.

Do I need a checkweigher as well?

If you have legal net content obligations, yes. A checkweigher verifies what the weigher produced and rejects outliers; the weigher alone cannot prove compliance.

How long does a multihead take to set up?

A good technician needs one to two days to tune feeds, combination limits, and dump timing on a new product. Budget that time into commissioning, not into the first production week.

Is a used multihead a good buy?

Sometimes. Check the load cells, the hopper condition, and whether the controller software is still supported. Hopper wear on abrasive product is the usual reason a used unit is for sale.

The three-year comparison, not the purchase order

What usually decides it

VFFS vs Flow Wrapper: Key Differences Explained

Introduction

Choosing between VFFS or Vertical Form Fill Seal and Flow Wrapper or Horizontal Form Fill Seal machines is a common dilemma for packaging managers. This comprehensive comparison helps you understand the key differences and select the right technology for your specific application.

1. Machine Orientation

VFFS machines feature vertical film feed from top to bottom. Product drops down through forming tube during operation. Compact floor footprint saves space. Height requires ceiling clearance consideration. Flow wrappers feature horizontal film feed. Product conveyed through machine horizontally. Longer floor footprint required. Lower profile design fits standard ceilings.

2. Product Compatibility

VFFS works best for granular products like snacks, nuts, and candy. Powders including flour, protein powder, and spices work well. Liquids such as milk, juice, and oil are suitable. Small parts like hardware and fasteners can be packaged. Flow wrapper works best for solid items like bread and chocolate bars. Regular-shaped products run most efficiently. Frozen foods including ice cream and vegetables are ideal. Delicate items like cookies and pastries need gentle handling.

3. Packaging Speed Comparison

VFFS speed range includes standard at 40-80 bags per minute. High-speed models achieve 80-120 plus bags per minute. Speed depends on product and bag size. Flow wrapper speed range includes standard at 80-150 packs per minute. High-speed models reach 150-250 plus packs per minute. Generally faster for solid products than VFFS.

4. Bag and Pack Style

VFFS options include pillow bags, gusseted bags, block bottom bags, and various seal styles. Flow wrapper options include fin seal packages, lap seal packages, crimp end seals, and modified atmosphere packs.

5. Film Requirements

VFFS film typically 30-100 microns thickness. Roll stock from single reel. Can handle laminates effectively. Flow wrapper film typically 20-80 microns. Wider film rolls required. Better print registration capability.

6. Floor Space Requirements
