FOAM FINISHED PAPER AND PAPER CONTAINER EMPLOYING THE PAPER

摘要

PROBLEM TO BE SOLVED: To form a foam layer having an enough uniform heat-insulation effect over the entire surface through a sufficient foam. SOLUTION: The finished paper consists of a laminate furnished with at least from the exterior surface side, a foam layer 2 of thermoplastic resin, a foundation material layer 1 consisting mainly of paper, and a thermoplastic resin layer 3, and the foam layer 2 of the thermoplastic resin is an ethylene-αolefin copolymer which is polymerized by the use of a single site catalyst. Theαolefin of the ethylene-αolefin copolymer is one, two or more selected from propylene, 1-butene, 3-methyl-1-butene, 4-methyl-1-pentene, 1-hexene, 1- octene, and decene. In addition, by the use of the foam finished paper, paper containers can be formed such as paper cup, paper tray, and beverage paper container.
