<p>PURPOSE:To obtain the adhesive strength of excellent heat resistance and chemical resistance to a polyolefinic plastic container by using chlorinated polypropylene as an adhesive agent of the label for sticking an in-mold label. CONSTITUTION:The label 1 for sticking the in-mold label is constituted of a plastic film base material 2, a printing ink layer 3 formed on the rear side thereof, and the chlorinated polypropylene adhesive agent layer 4 formed on the surface of the printing ink layer. The content of chlorine in this chlorinated polypropylene is adequately 10 to 50wt.%, the peak temp. of crystal melting thereof is preferably 130 to 85 deg.C and the quantity of heat for crystal melting is 0.5 to 10cal/g. The adhesion of the excellent heat resistance and chemical resistance is provided to the polyolefinic plastic container formed in a mold by using the chlorinated polypropylene as the label adhesive agent in such a manner.</p> |
