Snacks & confectionery
ขนมขบเคี้ยวและลูกอม
Speed and crispness. Most of this category is formed on the customer's own vertical line from a printed roll, so what leaves us is film rather than finished bags. That film has to run through a forming collar all day without wandering. Damp is the failure that shows up first: a snack goes soft long before it goes off.
Filled cold, not cooked in the pouch
What this category asks of the film
Eight things a pouch is asked to do. Three of them we rate here, as relative levels rather than measurements. They are the coarse filter a shortlist is drawn with. The other five are shown with the level left open, because nothing we have measured yet answers them.
- Holds air out
- Medium
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.
Damp is the failure that shows up first: a snack goes soft long before it goes off. That is the level held high, and oxygen and light sit a step lower, because these packs turn over fast. The harder brief here is mechanical. The film has to run through a forming collar all day without wandering.

Of every shape we convert, what this category reaches for.
Structures a quote would start from
Read straight off the barrier levels above: these are the laminates that meet all three. The final structure is chosen with your product, your shelf life and your filling line in the room.

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.
A quote request, not an order — nothing is bought and nothing is charged.
Have these to hand
- What goes in the pouch, and how many grams or millilitres
- Roughly how many, and by when
- Filled hot, cooked in the pouch, or neither
- Artwork if you have it — a sketch is enough to start
