Zusammenfassung: | PROBLEM TO BE SOLVED: To increase an adhesive strength between the inner face and the outer face of a base film and thereby eliminate a peeling phenomenon when cheese is packed by laminating an adhesive layer obtained by blending a specific amount of specific chemical compound on at least, one of the faces of the base film and further laminating a vinylidene chloride layer containing a specific chemical compound on the adhesive layer. SOLUTION: An adhesive layer containing 10-50 pts.wt. of isocyanate compound and 50-300 pts.wt. of a chemical compound containing a polar group which chemically reacts with the isocyanate compound for 100 pts.wt. of acrylic resin, is laminated on at least, one of the faces of biaxailly oriented polyester film or biaxiailly oriented polypropylene film as a base film. In addition, a vinylidene chloride layer containing 2-10 pts.wt. of cane sugar fatty ester with an HLB value of 7 or less for 100 pts.wt. of vinylidene chloride resin is laminated on the adhesive layer to manufacture the film for pack cheese. The appropriate example of the chemical compound containing the polar group is polyester polyol resin or polyether polyol resin. |
