Integrally molded and firmly bonded substrate, without coming off, for container having 3d colored dazzling effect and produced by in-mold injection molding, and manufacturing method of the same

Abstract

An integrally molded and firmly bonded substrate, without coming off, for container having 3D dazzling effect and produced by in-mold injection molding and a manufacturing method of the same are provided, in which aluminum plating operation is conducted on a film to form a reflective film, which is then firmly bonded with a base material, in liquid state having a temperature as high as 150° C.˜300° C., by the high adhesion of the base material produced in liquid state at high temperature, in turn a sheet-material processing operation is conducted. In this manner, adhesive and bonding layer (PET) is not needed for adhesion operation. Not only cost can be reduced but also degumming and peeling will not occur during in-mold injection molding process. Thus, yield rate can be increased and failure rate can be decreased. It can also be recycled for environmental purpose.
