POLYESTER FILM AND ITS MANUFACTURING METHOD

摘要

PROBLEM TO BE SOLVED: To provide a polymer film containing a polyethylene terephthalate obtained from a recovered polyethylene terephthalate molding as a main component after use as a film having characteristics of excellent mechanical properties such as a strength or the like by setting the polymer film to a whitened opaque concealable state. SOLUTION: The polyester film is obtained by compounding a poly (ε- caprolatone) of 2 to 20 wt.% with a flake manufactured by recycling a bottle made of the polyethylene terephthalate and then melting the blend. The polyester film has a dynamic elasticity of 3 GPa or more and white concealability.
