Spectrum One, Perkin Elmer. On the basis of the composition
of PP, PE and CP films in actual light PPW films, PP, PE and CP
films (1:1 mixture of PVC and PVDC) were obtained from commercial
wrap, food and beverage covers and considered as artificial
PPW films. These artificial films were cut to 1–5 cm size and used
for further experiments.
