Pet food
อาหารสัตว์เลี้ยง
Two very different jobs under one name.
Wet food is sterilised inside the sealed pouch. The laminate has to hold its seal all the way through the retort vessel and come out flat, not swollen.
Dry food is fatty, heavy, and opened every day for weeks. It asks for a different set of things: film tough enough not to split on a kibble corner, a base that stands up when the bag is full, and a zipper that still clicks shut when it is nearly empty.
Sterilised inside the sealed pouch — normal here, not an exception
What pet food asks of the film
Fat is what sets this category, and it attacks from two sides.
- Holds air out
- High
Oxygen is what turns oil rancid and takes the colour and the potency out of a product. It is the slowest of the three and the one that decides a shelf life in months rather than weeks.
- Holds damp out
- High
Damp is the fastest of the three to show. Water between the layers delaminates the film, and in Thai humidity a weak film can lose a product in a single wet season.
- Holds light out
- Medium
Light bleaches pigment and breaks down vitamins, and a clear window lets it through as readily as an open doorway does. It is also the only barrier a buyer can see is missing.
- Takes heat
- xxxWe have not rated this one yet
A retort pouch is cooked with the food inside it, under pressure, above boiling point. A film that survives filling does not automatically survive the retort.
- Takes a knock
- xxxWe have not rated this one yet
Dry pet food and coffee beans have corners. So does a pallet on a lorry. Most failures in transit are one hole, not a whole seam.
- Seals shut
- xxxWe have not rated this one yet
Every barrier above this one is undone by a seal that opens. It is also the layer that has to close cleanly through spilled powder and oil on a filling line running at speed.
- Prints true
- xxxWe have not rated this one yet
The shelf is the only place most products meet a buyer. Gravure prints from an engraved copper cylinder, which is why the same brown holds across a run instead of drifting.
- Goes back
- xxxWe have not rated this one yet
A laminate of three different plastics cannot be recycled as any one of them. A mono-material structure can, and every year it reaches the same shelf life on more of the jobs.
It takes up oxygen and turns rancid, so the oxygen barrier is held high — this is the row that decides whether shelf life reads in months or in weeks.
It wicks into the seal, so the sealant has to close through grease and kibble dust on a line running at speed.
Moisture is held high too. Light comes down a step: these bags live in a cupboard, not on a sunlit shelf.
Shapes that suit it
Two jobs, two sets of shapes.
Wet food, sterilised in the pouch
Dry food, opened and closed for weeks

Questions
What buyers ask before they order
- Can it keep moisture out, keep light out, hold a vacuum, take a retort?
Tell us what the pack has to survive and the film spec is built for it. That covers vacuum, and retort for a pouch that has to take pressure and heat and come out of a boiling or steaming cycle intact.
- Can you run food and cosmetics work, and can you certify it?
Yes, for every industry — the line runs food-grade film from end to end. A certificate of analysis (COA) goes out with every production lot and every delivery.
- What are you certified to?
ISO 9001:2015, GHPs, HACCP and BRC/IoP, all certified by BSI.
Ask for a quote on a pet food bag
A quote request, not an order — nothing is bought and nothing is charged.
Have these to hand
- Wet food or dry food, and how much goes in one bag
- Roughly how many bags, and by when
- Whether it is cooked in the pouch, and whether it needs a zipper
- Artwork if you have it — a sketch is enough to start
We answer within two working days.
