Abstract

PURPOSE: The titled material for an enclosed container, having well-balanced sealing strength with peel strength, and containing propylene polymer and a modified ethylenic polymer obtained by polymerizing ethylenic polymer with an aromatic vinyl monomer at a specified ratio in a specific proportion.
CONSTITUTION: A material obtained by incorporating (A) 10W80pts.wt. propylene polymer, e.g. crystalline propylene-ethylene random copolymer, with (B) 90W 20pts.wt. modified ethylenic polymer prepared by grafting 60W5wt% aromatic vinyl monomer, preferably styrene expressed by the formula (R1 is H or 1W4C alkyl; R2, R3, R4, R5 and R6 are H, halogen atom, etc., respectively), containing preferably 0.1W2.0wt% polymerization initiator dissolved therein, onto 40W95wt% ethylenic polymer, preferably ethylene-vinyl acetate copolymer, as main components.
EFFECT: The material is releasable smoothly with a constant and uniform force by hand and has improved film processability.
