<p>PROBLEM TO BE SOLVED: To obtain a film excellent in suitableness for stretch packaging by molding a resin composition mainly comprising an ethylene-(meth)acrylic acid-(meth)acrylic ester terpolymer containing a specific amount of (meth) acrylic ester units or an ionomer. SOLUTION: An ethylene-(meth)acrylic acid-(meth)acrylic ester terpolymer containing 7 wt.% or lower, especially 5 wt.% or lower, (meth)acrylic ester units or an ionomer ionized with an alkali metal is used. If necessary, the resin composition contains an antifogging agent and a tackifier. Among (meth)acrylic esters, one having a 1-10C alkyl group, especially isobutyl (meth)acrylate, is suitable. Usually, it is preferable that the content of (meth)acrylic acid units in the terpolymer is 5-20 wt.%. Usually, an ionomer having a degree of ionization of 0.1-30% is used. The film can be prepared even by the T-die method.</p> |
