Among them, PE is suitable for low temperature use, and RCPP is suitable for high temperature cooking;
PA is to increase physical strength and puncture resistance;
AL aluminum foil is to increase the barrier performance and shading;
PET, increased mechanical strength, excellent stiffness.
Then according to the needs, combination, various properties, there are also transparent, in order to increase the barrier performance, use the water-resistant PVA high barrier coating.
