Film for wrapping

Abstract

A film having a large tensile stress in the machine direction, excellent mechanical properties and stretch-wrapping property, and that is less broken at the time of wrapping, can be favorably torn off in the transverse direction, can be intimately adhered on the container walls to be wrapped, and excellently restores its shape after it is depressed and deformed as a result of wrapping. The film for stretch-wrapping is formed of a resin composition containing, as a chief component, an ethylene / (meth)acrylic acid / (meth)acrylic acid ester terpolymer that contains not more than 7% by weight of a (meth)acrylic acid ester unit, and, optionally, containing an anti-fogging agent or a tackifier.

Description

TECHNICAL FIELD This application claims priority to Japanese Patent Application No. 11-103239 field on Apr. 9, 1999, which is incorporated herein by reference. The present invention relates to a film for stretch-wrapping. More particularly, the invention relates to a film for stretch-wrapping comprising chiefly an ethylene-(meth)acrylic acid-(meth)acrylic acid ester terpolymer or a metal salt ionomer thereof. BACKGROUND ART PVC films have heretofore been chiefly used as stretchable films (for wrapping foamed polystyrene trays containing foods) for business use such as in supermarkets and convenience stores. However, from the environmental viewpoints in recent years, it has been urged to provide a substitute for the PVC. In the field of stretchable films for stretch-wrapping, the PVC films have rapidly been substituted by the olefin resin films. Many films for stretch-wrapping have so far been proposed using an ethylene / unsaturated carboxylic acid copolymer, an ethylene / unsaturat...
