Exploitive properties of polymer films for food packaging, such as light, strength and oxygen permeation before and after the light ageing and thermal stability have been studied. The objects of the research were single-layer films of high-pressure polyethylene, biaxial-oriented polypropylene and polyethyleneterephthalate, as well as multilayer films on the basis of high-pressure polyethylene, polyamide and polyvinyl alcohol.
