Standard structures

Twelve structures the plant says it can build, and three answers it has not given yet.

Production was asked one question about each structure below — can we build this — and answered yes to all twelve. They were also asked three things about each one, and those boxes came back empty. Both halves are on this page, because a list of what a supplier can do is worth less than a list that also says where the knowing stops.

The structures are the world market's, not ours. They were taken from foreign converters' published specifications so that production had something concrete to correct rather than a blank page to fill. What this plant confirmed is that it can build them.

What the sheet is measuring against

Five things arrive from outside and go after what is in the pouch. Every column below exists because of one of them. Four are answered here; the fifth has no column on this sheet, which says nothing about whether it turns up on a lorry.

  • The Air

    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.

  • The Damp

    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.

    Answered below under Moisture barrier

  • The Glare

    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.

  • The Boil

    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.

  • The Corner

    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.
