ENGAGING DEVICE AND WRAPPING BAG HAVING THE SAME
Document Type and Number:
Japanese Patent JP3773279
Kind Code:
B2
Abstract:
PURPOSE: To obtain a wrapping bag having an engaging device which is excellent in heat-sealability at low temperature, flexibility, easiness in crushing or the like, unsealability and re-sealability, and which has good appearance by forming of random ternary copolymer of crystalline propylene, ethylene and butene-1.
CONSTITUTION: An engaging device 1 is formed of random ternary copolymer of crystalline propylene, ethylene and butene-1. Copolymer having a melt index of 0.5 to 20g/10min. may be used as random ternary copolymer of crystalline propylene, ethylene and butene-1. This random ternary copolymer of crystalline propylene, ethylene and butene-1 is ternary random copolymer mainly comprising propylene, wherein typically an ethylene content is 1.0 to 9.0wt.% and a butene-1 content is O.5 to 9.0wt.%. The engaging device 1 is typically fabricated by means of extrusion molding. As a method for attaching the engaging device 1 to a bag, it is fused 2 to a bag body made of a laminated film comprising PET/CPP.
