積層体６を形成する。To explain the details of the above-mentioned laminate, first, a metal coating 3 such as chromium is deposited on one side of the fluororesin film 2 by vapor deposition, sputtering, etc., and vinyl chloride 4 is applied to the surface of this coating 3 using an adhesive 5. The metal-like plastic laminate 6 is formed by adhering the metal-like plastic laminate 6.
上記フッ素樹脂フィルムは伸び率４〜５００％であり、
伸縮し易いものであるから伸びを生じても亀裂を生じな
い。The fluororesin film has an elongation rate of 4 to 500%,
Since it is easy to expand and contract, it does not cause cracks even if it is stretched.
又、これに被膜する金属は３〜４００ Ａ （０，３〜
０．４μ）であるため多少の伸びでも亀裂を生じる。Also, the metal coated on this is 3~400A (0,3~
0.4 μ), cracks occur even with some elongation.
そのため、該金属調プラスチック積層体６のフッ素樹脂
フィルム２の表面に、該プラスチック積層体６０幅より

うにし、塗装後、該ＰＥＴフィルム１を剥離する。In addition, when painting other coating parts 8 other than the surface part of the laminate 6 of the molded article 7 with a built-in laminate as described above, the PET film 1 is used as a masking tape and the width of the laminate 6 is narrower than the width of the laminate 6.
The PET film 1 is used by being attached to the surface of the laminate 6 to prevent a coating film from adhering to the surface of the metal-like plastic laminate 6, and after painting, the PET film 1 is peeled off.

裂が発生することを防止することができる。<Effects> As described above, this invention produces a metal-like plastic laminate in which a metal coating is adhered to one side of a fluororesin film and vinyl chloride is adhered to this coating surface, and the fluororesin film is exposed on the surface. Before molding into a built-in molded product, a low-stretch PET film is bonded to a fluororesin film and molded to suppress the expansion and contraction of the metal-like plastic laminate. It is possible to prevent cracks from occurring in the metal.
従って、従来技術により成形した製品のような金属被膜
の亀裂は生じない。Therefore, cracks in the metal coating do not occur as in products molded according to the prior art.

できる等の効果がある。In addition, when painting the surface of a molded product with a built-in laminate, by pasting a PET film on the surface of the laminate as a masking tape before molding, the PET film can suppress the expansion and contraction of the metal-like plastic laminate. It is possible to prevent cracks from occurring in the metal that is adhered to it, and it can also act as a masking tape, so it is much more troublesome than the conventional method of pasting masking tape and painting. This has the effect of reducing the need for painting and allowing accurate painting.
