Custom Printed Roll Stock Film for VFFS and Flow-Wrap Lines
Custom printed roll stock film for VFFS is made for lines that already run: you have a form-fill-seal or flow-wrap machine, and you need printed, laminated film cut to its width and repeat length.
It is not a pre-made bag. If you fill into finished pouches, a stand-up or flat bottom bag is the better format. If you form the pack on your own machine, this is the film for it. It is printed and laminated on the roll, with barrier structures from metallized PET/PE up to PET/AL/PE foil laminate.
Film width and repeat length are matched to your machine. Print is digital with no plate cost, or gravure for stable repeat runs. MOQ is 100 kg per design, and production takes 7-15 days after artwork approval.
- Machine-matched film — Film width and repeat length are set from your VFFS or flow-wrap model.
- Roll sample first — A roll sample goes out before the production run.
- Food-contact paperwork — The PE film has an FDA 21 CFR 177.1520 test report.

Which Barrier Structure Fits Your Product and Target Shelf Life
Start with what your product is sensitive to: oxygen, moisture or light.
Metallized PET versus aluminum foil
VMPET/PE structures give a good barrier for many dry snacks and are often the first option to price. PET/AL/PE foil laminate gives the highest barrier against oxygen, water vapor and light, and suits products with fat that goes rancid or aroma that must stay in. Total laminate thickness usually sits between 90 and 130 µm, depending on structure and the machine's sealing window.
Shelf life is a range, not a guarantee
Shelf life figures for any structure are indicative industry ranges. Actual results depend on recipe, fat content, fill weight, seal quality and storage conditions. We validate the structure against your own product before tooling is cut, and we recommend one structure in writing, with each alternative priced.
A good fit when
- Dry snacks with moderate fat: VMPET/PE is usually the starting point
- Fatty, aromatic or light-sensitive products: PET/AL/PE is usually considered
Consider another option when
- Products that need a retort cycle: ask for a retort-rated structure instead
- Fills above roughly 50 lb: woven or multiwall sacks usually suit better
Roll Film That Runs on Your Machine: Film Width, Repeat Length and Core
A film that is wrong by a few millimeters will not track or seal properly.
What we need from you
Send the VFFS or flow-wrap machine model, the film width, the repeat length and the maximum roll diameter. If you do not have the numbers, a photo of the machine nameplate or a sample of the film you run now is enough for us to work out the rest. Core size and unwind direction are confirmed at the same time.
Roll sample before the run
Before production, a roll sample goes to you for a trial on your own line. You check tracking, registration and seal strength at your normal speed, and any change is made before the full run. Our free design team lays out the print from finished files, or from an idea or reference photo.
Snack, Coffee, Tea, Frozen and Pet Food Lines: What Each Asks of the Film
Each line stresses the film in a different way.
Snack VFFS lines
Oxygen and light barrier protect fried or fatty snacks, and the seal must hold through crumb contamination. We match the sealing layer to your jaw temperature and dwell time.
Coffee and tea
Aroma retention calls for a high-barrier layer, usually foil or high-barrier laminate. Coffee that degasses needs a structure that fits your valve or venting method.
Frozen food
The film must stay flexible and seal well at low temperature. Seal layer and total thickness are chosen for your fill weight and handling.
Pet food
Fat content drives the barrier choice, and heavier fills need stronger seals. We confirm the structure against your recipe.
High-speed flow-wrap
Registration and coefficient of friction matter more at speed. The roll sample is run at your normal line speed before approval.
Digital or Gravure Printed Film: Plate-Free Trials and Repeat Runs
Pick by how stable your artwork and volumes are.
Digital print
- Plate cost: None
- Best for: New recipes, multi-SKU ranges, market tests
- MOQ per design: 100 kg
- Color count: Affects price, itemized on quote
Gravure print
- Plate cost: Cylinders per design
- Best for: Stable repeat orders
- MOQ per design: 100 kg
- Color count: Affects price, itemized on quote
Roll Stock Film MOQ: 100 kg Per Design and What Happens After Approval
The MOQ is 100 kg per design, which suits small SKU runs and multi-design orders.
Terms for wholesale, OEM/ODM and private label
Wholesale buyers can split volume across designs at 100 kg each. OEM/ODM and private label customers can start with a small run and repeat on gravure once the artwork settles. Production takes 7-15 days after artwork proof approval. Sea, air or express shipping is quoted with the order, and we do not promise a transit time.
Food-Contact Paperwork for Printed Film: FDA 21 CFR 177.1520 Report, ISO 22000, ISO 9001
The documents you need for your own file are available.

FDA 21 CFR 177.1520 test report
Our PE food-contact film passed an independent lab test against FDA 21 CFR 177.1520, report HLF24003138EA, March 2024. The FDA does not certify packaging, so this is test evidence, not a certificate.
-
ISO 22000

-
ISO 9001
Quality management certificate, available on request and sent with the quote.
Follow your bag through the plant

Incoming inspection
Film rolls are checked before they reach the press.
Printing
Your artwork is printed in house, up to 9 colours.
Dry lamination
Printed film is bonded to its other layers.
Slitting
Wide film is cut to the width of your bag.
Bag making and finishing
Bags are sealed and fitted with zippers or valves.
Inspection and packing
Finished bags are inspected, then packed in cartons.
Printed VFFS Film Questions on Barrier, Machine Fit, Samples and Foil
- Can you guarantee shelf life?
- No. Shelf life depends on your recipe, fat content, fill weight, seal quality and storage. We validate the structure against your product before tooling and give an indicative range.
- How do I confirm film width and machine fit?
- Send the machine model, film width, repeat length and roll diameter. We match the film and confirm with a roll sample run on your line.
- Is the sample free?
- Yes, the sample is free. You pay the courier.
- What is the MOQ?
- 100 kg per design for roll stock film. Digital print needs no plates.
- Are foil structures recyclable?
- No. We do not describe foil or Mylar structures as recyclable. If you need a different end-of-life route, ask about that exact structure and we will quote it with its documents.
Send Your Product, Machine Model and Roll Size for an Itemized Quote and a Roll Sample
