CONTAINER PACKAGING BODY, AND HEAT-SHRINKABLE MULTI-LAYER FILM USED THEREFOR

摘要

PROBLEM TO BE SOLVED: To provide a container packaging body wherein a lid material is sealed by heat sealing on the flange face of a container whose inner surface is made of a polypropylene resin, and to provide a heat-shrinkable multi-layer film used for the lid material for the container packaging body which offers superior sealing and unsealing properties, and forms no wrinkle fine in appearance even if a content rises more than the flange face of the container.

SOLUTION: A heat sealing layer made of an ethylene-vinyl acetate copolymer resin comprising 7-20 wt.% vinyl acetate and the heat-shrinkable lid material 5 are heat-sealed on the flange face 4 of the container 2 whose inner surface is made of a polypropylene resin. The lid material 5 is then heated to be shrunk to provide the container packaging body which has superior sealing and unsealing properties and forms no wrinkle fine in appearance.
