PURPOSE: To provide a packaging material comprising a polymer film useful for packaging shredded cheese by a molding/filling/sealing device and having hot and cold sealing properties even if a contaminant is present in the seal region of a package and also having low seal starting temp., toughness and severe use resistance. CONSTITUTION: A film comprises a center layer 16 containing an oxygen barrier material, the polyamide inner layers 14 arranged on the respective surfaces of the center layer 16, a sealant layer 20 containing an extremely low density polyethylene, a heat resistant outer layer 10 and the chemically modified polyolefin-containing intermediate layers arranged between the polyamide inner layer 14, a sealant layer 20 and an outer layer 10. This film can be bonded to an additional film to form a laminate and, according to circumstances, a trap print surface is provided. |
