What wrapping materials are typically used on HFFS machines?
A. Typically laminates like Polyester / OPP, BOPP / BOPP, CPP / BOPP, Polyester / PE or plain BOPP are used in HFFS machines. Advantage of using laminates is that outer layer can be reverse printed to give a glossy print appearance on the outside at the same time preventing printing chemicals coming in contact with edible products like biscuits. All materials used on HFFS must have sealable inside surface.
