Title:
LAMINATED FILM FOR COATING METAL CAN
Document Type and Number:
Japanese Patent JP2003200530
Kind Code:
A
Abstract:

To provide a laminated film for coating a metal can capable of preventing the lowering of the appearance quality of the surface of the metal can.

The laminated film for coating the metal can is constituted of the adhesive layer bonded to the surface of the metal can and the resin layer laminated on the adhesive layer. The haze value thereof is 30-90%. The adhesive layer contains 30 wt.% or more of a polyester with a melting point of 190-245°C. The resin layer contains 0.1-10 wt.% of inert particles with a mean particle size of 0.1-10 μm. The transmissivity of scattering light of the laminated film for the metal can is preferably not less than 30%. When the resin layer is formed by stretching the film, a void diameter ratio calculated by dividing the diameter of voids formed around the inert particles by the particle size of inert particles is preferably 2.5-6.0.
