heal.abstract	The effect of accelerated weathering on the structure and properties of single, metallized and multilayer films used in food packaging was studied, by exposing specimens of the above films to repeated ageing cycles, under the combined action of UV radiation, humidity and heat. Films made of polypropylene (PP) undergo severe chain scission upon irradiation and lose mechanical strength. The metallic coating cannot prevent PP from degradation. PE and PET films show modest decrease of mechanical properties. Multilayer films (PE/EVOH/PE, PE//PET) present a decrease of mechanical properties reflecting degradation of their weak component.	en
