Custom printed aluminum foil vacuum bags use a PET/AL/PE laminate, so the foil layer stops oxygen, moisture and light that clear vacuum film lets through in part.
The outer PET layer carries your print. The aluminum layer is the barrier. The inner PE layer forms the heat seal that holds the vacuum. We print, laminate and make these bags in our own 6,520 m² cleanroom plant in Shenzhen, with digital printing from 1,000 pcs per design and gravure from 10,000 pcs per design.
They suit meat and seafood, coffee beans, cheese and deli, freeze-dried food and pet food. Size, structure, print and extras are made to your spec. Production takes 7-15 days after artwork approval.
The product decides barrier, puncture resistance and fittings.
Bones, shells and ice can pierce a thin film. Foil laminates can be built thicker or with a nylon layer for puncture resistance. Frozen products also need a seal that survives cold handling.
Roasted beans release CO2, so a degassing valve on a flat bottom or stand-up bag is usually needed. Foil blocks light and oxygen. A valve is not needed for ground coffee that has fully degassed.
Moisture retention and oxygen barrier matter most. A flat vacuum pouch with a wide seal and tear notch is typical. Windows are optional.
Dry product needs a strong moisture and light barrier. Stand-up bags with zipper suit repeat opening. Sharp pieces call for a tougher inner layer.
Five choices shape the bag. Final specs are confirmed in your quote.
A flat pouch is the usual vacuum format because it lies flat and seals close to the product. A stand-up or flat bottom bag gives shelf presence but holds less vacuum shape. Size follows the product volume plus the sealing area, and the free Pouch Capacity calculator on our site gives a starting figure. Tell us fill weight and product shape and we recommend a size.
Film thickness sets puncture resistance and stiffness. Thicker suits sharp or heavy contents, thinner suits soft items and lowers cost. Seal width affects strength and the room left for sealer variation. Options include tear notch, zipper, hang hole, window and degassing valve. Each extra is itemized on the quote. Structure and size advice is free.
A vacuum bag only works if the seal holds.
Printing, lamination and bag making run in our own cleanroom plant, so films and bags are not handled across outside sites.
Heat seals are checked for width, fusion and wrinkles, because a weak or creased seal loses vacuum first.
Bags are leak-tested before shipment. Pinholes and open seals are rejected rather than packed.
Eleven checks run before packing, covering print, size, seal and appearance. We do not publish test values without a defined spec.
Bags are counted and packed in cartons. Carton CBM and weight can be worked out with our free calculator.
Documents are on the website and copies go out with the quote.
The PE film is tested to FDA 21 CFR food-contact requirements, with a test report. We do not describe it as FDA approved or certified.
Production runs under an ISO 22000 food safety management system. Our plant also holds ISO 9001 quality management.
Tell us your market and what your auditors ask for. We confirm which files we can supply for your structure.
We make no recyclability claim for foil bags. Other structures are discussed only if you ask for that exact build.
Pick by order size and how often you reorder.
Specialty builds such as compostable or recycled-content films carry a higher MOQ, confirmed in the quote. Shipping is quoted separately.
