易い問題力INDUSTRIAL APPLICATION FIELD The present invention relates to improvements in vacuum-formed phase sheets. Conventional technology Acrylic resin sheets have a good surface gloss. It is often used for interior decoration, signboards, etc. In order to prevent damage from handling and stacking during vacuum forming, tri-hanging, etc., medical checkup paper and adhesive film are pasted. During vacuum forming, the protective paper and protective film are peeled off before forming. This is because - when vacuum forming is performed with the protective paper pasted, the protective paper does not follow the elongation of the vacuum forming, and RFC forming is not possible. Also. When a vinylidene chloride film is used as a protective film, the film should not be easily peeled off from the molded product after molding, and when polyethylene film is used, the density of the molded sheet may be poor, and the film may not be easily peeled off during vacuum forming. Create air between the protective film and the sheet h5! j. The protective film was removed during vacuum forming in all cases to prevent engraving from occurring. Problems to be Solved by the Invention As mentioned above, in the past, the protective paper or holding film was peeled off prior to vacuum forming. In addition, if the molded product has a three-dimensional shape with a double uneven surface, it is easy to apply a protective film to the molded product.

An object of the present invention is to provide a vacuum-formed sheet 1 that can be vacuum-formed with a protective sheet attached, and also allows the top sheet to be easily peeled off from the RFC image product after molding if necessary. . Means for Solving the Problems In order to achieve the above objectives, the present invention provides vacuum-formed thermoplastic resin sheet bloody C2) i
” - A protective sheet with a lower tensile strength than the above-mentioned sheet and a higher stretchability than the above-mentioned sheet during vacuum forming without being connected to electricity. At times, it is stretched along the hJt4 award certificate without affecting the moldability.And since the molded product sheet is only in close contact with the molded product and is not attached, it can be easily stretched from the molded product as appropriate after molding. The peeling force can be τ.Example Next, an example of the present invention will be explained.Example I MMA/AB8 2m sheet (m J!1.2.5 m

Paste on the sheet 41. Vacuum forming was performed in the same manner. The results of 7 are shown in table w11. W & 1 In Table Example 1, low density polyethylene is supplemented with the strength of EVA to maintain W after molding! This makes it easier to peel off the II film. Effects of the Invention As mentioned above, the present invention applies a protective film to the product (vacuum forming can be performed well as it is). It can be easily peeled off from RFC shaped products as appropriate.
