Foil Barrier Pouches

Foil barrier pouches are built on a PET/AL/PE laminate, where an aluminium layer stops oxygen, moisture, light and aroma almost completely. We run them as stand up pouches, flat bottom bags and flat sachets from 5 g to 25 kg, with zippers and one-way degassing valves. It is the structure for coffee, protein powder, smell-proof mylar bags and anything whose fat content attacks a lighter film. Foil is opaque to metal detection, so lines that inspect after filling take metallised PET instead.
