Title:
ポリエステルフィルム
Document Type and Number:
Japanese Patent JP3600622
Kind Code:
B2
Abstract:
Provided is a polyester film containing a lubricant having an average particle diameter of 0.001 to 2.5 mu m in an amount of 0.01 to 5.0% by weight and suited for the lamination onto the surface that comes in contact with the contents, of an easy-open can cap. The polyester film has a plain orientation coefficient of 0.115 to 0.140, two or more endothermic peaks in DSC curve in the range of 170 to 270 DEG C, a peak temperature of 60 to 120 DEG C of a complex elastic modulus (E'') in water and an intrinsic viscosity of 0.50 to 0.64 dl/g. Having these features, the polyester film laminated onto a metal sheet is excellent in can-capping processability and in corrosion resistance even after holding at high temperature.
