Crystalline propylene copolymer compositions having a low seal temperature and good ink adhesion.

摘要

Disclosed are a crystalline propylene copolymer composition, film, sheet and plate made therefrom and laminates wherein at least one layer is made therefrom, having low seal initiation temperature and good ink adhesion properties. The composition comprises (percent by weight): A) 20-60% of a crystalline copolymer of propylene with 1 to 5% ethylene; and B) 40-80% of a crystalline copolymer of propylene with 1 to 5% ethylene and 6 to 15% C4-C8 alpha -olefin. In the composition the total content of ethylene being 1% to 5% and of C4-C8 alpha -olefin being 2.4% to 12%.
