Сomparative characteristics nine-layer packaging films on the basis of the polyolefin plastomer (POP), polyamide (PA) and copolymer of ethylene vinyl alcohol (CEVA) is the spectral transmittance, absorbance and indicators tensile strength of samples before and after the ultraviolet (UV) radiation have been studied, and also their thermogravimetric analysis has been held. It is established that more light resistance has medium barrier film thickness of 50 microns, based on POP and PA, and the smaller the change of strength properties after ultraviolet aging was recorded on high barrier film thickness of 110 mm, optionally contain layers of CEVA, which, in addition, found and high resistance to thermal-oxidative destruction.
