Abstract

PURPOSE: The titled film that is composed of an easily heat-sealable composition layer resulting from depolymerization of a proplyene polymer and a butene-1 polymer in the presence of a radical initiator and of a crylstalline polypropylene layer, thus being suitably used for wrapping food products because of its high transparency.
CONSTITUTION: (A) A polymer of propylene and/or a copolymer of propylene and an α-olefin such as ethylene and (B) a polymer of butene-1 and/or copolymer of butene-1 and an α-olefin such as ethylene are depolymerized together in the presence of a radical initiator to give an easily heat-sealable resin composition. Then, the resultant resin composition is laminated on at least one side of a crystalline polypropylene sheet to produce the objective composite film. Preferably, the amount of component A is 40W95pts.wt. and component B, 5W60pts.
