Resumo
The influence of electron-beam irradiation on mechanical properties of commercial multilayer flexible
packaging materials based on coextruded and laminated polypropylene (PP), low-density polyethylene
(LDPE), ethylene vinyl alcohol copolymer (EVOH) and poly(ethylene terephthalate) (PET), irradiated
with doses up to 120 kGy, was studied. The tensile strength and elongation at break of the irradiated
PET/PP film increase, while the penetration and sealing resistance decreased. In addition, the
irradiated PET/LDPE/EVOH/LDPE film presented increase in the tensile strength on some radiation
doses and decrease of the penetration and sealing resistance, except for sealing resistance at radiation
dose of 15 kGy that resulted in a slight increase of ca 4%.
