<P>PROBLEM TO BE SOLVED: To provide a heat-sealable resin composition which can be used as a sealant having a heat seal strength enough to protect the contents in a container made of a polystyrene resin and can be remarkably reduced in cost; and a film made thereof. <P>SOLUTION: This heat-sealable resin composition comprises 100 pts.wt. polyolefin resin and 0.01-5 pts.wt. styrene polymer having a weight average molecular weight, measured by gel permeation chronatograply, of 1,000-40,000 and at least one epoxy group in its molecule. The composition is used for preparing a film and a laminate. <P>COPYRIGHT: (C)2004,JPO |
