Flexible Packaging is produced through adding value to a wide variety of substrate materials including plastic films, paper and aluminium foil – either separately or in combination – mainly for primary retail food packaging and non-food packaging applications such as pet food, tobacco, cosmetics and personal care, household detergents, and pharmaceutical and medical products. This specifically excludes shrink and stretch films used for secondary packaging, pallet hoods and pallet wrap, carrier bags, supermarket and self-service counter bags, silage bags, refuse and industrial sacks, etc. Inevitably, there remain some grey areas.
