Title:
POLYESTER COMPOSITE FILM FOR LAMINATION OF METAL
Document Type and Number:
Japanese Patent JP3304003
Kind Code:
B2
Abstract:
PURPOSE: To provide a polyester composite film for the lamination of a metal excellent in deformability, impact resistance, close adhesiveness and heat resistance at the time of can manufacturing, not generating the sticking of a punch or the mark of a feed pin and excellent in flavor resistance.
CONSTITUTION: A polyester composite film consists of layers A, B where the layer A is composed of polyethylene terephthalate or polyethylene terephthalate isophthalate with an m.p. of 210°C or higher and the layer B is composed of polyester with an m.p. of 180-230°C and Tg of 40°C or lower containing 50mol% or more of a terephthalic acid residue, 5-50mol% of a 10C aliphatic dicarboxylic acid residue and 60mol% or more of EG.
