Title:
EASILY TEARABLE MULTILAYERED FILM
Document Type and Number:
Japanese Patent JP3133410
Kind Code:
B2
Abstract:
PURPOSE: To ensure excellent gas barrier properties, transparency and tearable properties by laminating a layer composed of a easily polyamide resin or an ethylene/vinyl alcohol copolymer and a polyolefin resin and a layer composed of a resin based on polyolefin.
CONSTITUTION: An easily tearable multilayered film is constituted by laminating at least two specific layers. That is, at least one layer is formed from a composition prepared by mixing 85-97wt.% of a polyamide resin or an ethylene/vinyl alcohol copolymer and 15-3wt.% of a polyolefin resin and at least the other one layer is formed from a resin based on polyolefin. Two layers are subjected to co-extrusion molding or laminate molding. By this method, the easy tearing multilayered film excellent in gas barrier properties and transparency, capable of being easily torn at the time of drying or hydration and suitable for a packing material of perishable foods is obtained.
