いられている。 Conventionally, packaging containers for hams and sausages have been made with polyvinyl chloride or unstretched polypropylene, saponified ethylene-vinyl acetate copolymer, and ionomer resin in order, taking into consideration the warping of the molded product after sealing and gas barrier properties. Generally used packaging materials are made of laminated packaging materials, while the lid material is made of sequentially laminated materials of stretched polypropylene, KM cellophane, ionomer resin, or ethylene-vinyl acetate copolymer.

考案を完成したものである。 In order to eliminate the above drawbacks, the inventor of the present invention has conducted research and found that by using polybutylene terephthalate (preferably 30 to 60 μm in thickness) as a heat-resistant packaging material with good moldability, the problem of boiling, which had previously been a problem, was solved. In addition to suppressing the deterioration of the appearance of the packaging material after sealing, the packaging material is made by laminating films of polybutylene terephthalate, saponified ethylene-vinyl acetate copolymer, and low-density polyethylene as the material for the molded body. We also discovered that this problem could be solved by using a packaging material made of sequentially laminated films of oriented polypropylene, saponified ethylene-vinyl acetate copolymer, and ionomer resin as the lid material, and based on this knowledge, we completed the present invention. be.
