Abstract

PURPOSE:To improve the bonding strength and whitening resistance by using a material obtained by mixing a specific ethylene-propylene block copolymer, a specific ethylene-propylene random copolymer, and propylene homopolymer. CONSTITUTION:A cell case is manufactured by using a material obtained by mixing an ethylene-propylene block copolymer, 5-15wt% an ethylene-propylene random copolymer containing 1-4wt% ethylenic component, and 5-15wt% propylene homopolymer. The said ethylene-propylene block copolymer contains 10-25wt% polyethylene component and also its propylene chain contains 2-3wt% ethylenic component. Thus, a cell case which is excellent in whitening resistance as well as great in bonding strength and rigidity can be obtained.
