いる。 In recent years, foamed polystyrene sheets have been widely used as trays and other molded products with excellent heat insulation properties, but in this invention, the foamed polystyrene sheets were made to have a metallic appearance and were further strengthened. The present invention aims to provide a laminated sheet for container molding in combination with a metal vapor deposited layer.

状に形成してなることを特徴とするものである。 That is, the structure of the laminated sheet for container molding according to this invention is such that a metallized film having a metallized layer on one side is bonded to an adhesive layer on both sides of a foamed polystyrene sheet so that both metallized layers are on the inside. It is characterized in that it is joined via a .

提供できることになる。 The laminated sheet for container molding according to this invention is constructed as described above, and is used as a laminated sheet for molding trays and other items.Due to three-dimensional molding from the sheet, cracks occur in foamed sheets with metal foil, but the metal-deposited layer Therefore, it can be molded well and can be molded well into foamed polystyrene sheets without cracking, resulting in very good molding processability. Furthermore, the metal vapor deposited layers 20, 20' do not peel off even during molding, and molded products of various shapes can be provided in almost the same way as in the case of a foamed polystyrene sheet alone.

となり得る。 In addition, molded products such as trays do not have the appearance of foamed polystyrene, but can have a metallic feel due to metallized film, giving a heavy appearance, a good feel, and a remarkable printing effect, making them beautiful and sanitary. It is easy to reflect light and heat from the outside, and as a packaged product, it has the great advantage of insulation and heat retention as a whole. In addition, it helps prevent the foamed polystyrene sheet as the core material from chipping and tearing, and together with the cushioning properties unique to the foamed polystyrene sheet as the core material, it adds extremely robustness and can be used for trays and other various products without sacrificing any lightness. It can be a particularly suitable sheet for molding packaging containers and the like.
