Twelve bag and film formats, all manufactured to your artwork and your filling line - serving the food, electronics, pharmaceutical and chemical industries. As a food packaging manufacturer we produce custom printed pouches, high-barrier bags and laminated film rolls for overseas brands. Every structure below can be supplied as a stock trial sample before you commit to a production run.

Structure guide

Which film structure do I need?

A quick reference for the most requested combinations. Send us your product and shelf-life target and we will confirm the structure in writing.

Typical laminated structures by application
Application Recommended structure Thickness Why it works
Coffee beans & ground coffee PET/VMPET/PE with valve 110 - 130 micron Metallised barrier against oxygen and moisture; valve vents CO2 without letting air in.
Dry snacks & confectionery PET/PE or BOPP/CPP 80 - 100 micron Cost-efficient moisture barrier with crisp print and good seal strength.
Frozen & chilled food PA/PE co-extruded 70 - 90 micron Puncture resistant at low temperature and stable through the vacuum cycle.
Long shelf-life dry goods PET/AL/NY/PE 130 - 150 micron Aluminium foil gives a near-total light, oxygen and moisture barrier.
Pet food & 5 kg bulk packs PET/AL/PE quad seal 150 - 180 micron Rigid flat base carries the weight and stacks neatly on pallets.
Powders on a VFFS line PET/AL/PE roll stock 90 - 120 micron Low coefficient of friction for smooth feeding at high line speed.
Compostable / recyclable option PLA/PLA or mono-PE 60 - 110 micron Supports sustainability claims; slightly shorter shelf life than foil structures.
