- In case of containers of in-mold injection molding having 3D pattern variation animation colored dazzling visual effect provided on its surface currently available on the market, electroplating operation is firstly conducted on a polyethylene terephthalate (PET) film so as to form a reflective film, and then a bonding layer with one PET layer thereon is adhered on the reflective film by adhesive and a base material with one polypropylene (PP) layer thereon is adhered to the bonding layer. Next, embossing, varnishing, or printing operations are conducted so as to form a substrate that can be conducted with in-mold injection molding operation in mould so as to produce containers.
- The above substrate manufacturing method can achieve expected effect of producing containers having 3D pattern variation animation colored dazzling visual effect. However, it is found in its overall implementation that the reflective film after electroplating is unable to be bonded and integrally molded directly with the base material. Thus, a bonding layer (PET) should be provided between the reflective film and the base material, then the reflective film is adhered to the bonding layer (PET) by adhesive, and the bonding layer (PET) is also adhered to the base material by adhesive. That is to say, two adhesion processes are required between the reflective film and the bonding layer (PET) as well as between the bonding layer (PET) and the base material; hence this will result in higher manufacturing cost. Furthermore, in the process of in-mold injection molding after being disposed in the mould, the substrate will contact with plastic material with high temperature in the mould. As adhesive cannot tolerate high temperature, degumming phenomena is easily produced under high temperature condition. Therefore, intolerability of the adhesive to the high temperature in the mould will cause peeling or detachment between the reflective film and the bonding layer (PET) or between the bonding layer (PET) and the base material, so that the containers thus produced is prone to have defects which is unfavorable to the yield rate of production.
