しかもエアキャップ部分が非常に嵩高い難点もあった。[Detailed description of the invention] This invention relates to a laminate that has good shape retention and excellent cushioning properties.The so-called air cap sheet, which has a large number of independent air chambers, is used for packaging. It is widely used as a cushioning material, etc., but since only flexible materials such as polyethylene films or sheets are used, it is easy to wrap around the packaged item, but it has low rigidity and is not self-supporting. Although it is suitable for simple cushioning purposes for relatively lightweight packaged items due to its inferior strength and lack of stiffness, it is not suitable for forming itself into containers, as well as various electrical appliances and various machinery that have functional parts. Due to its relatively heavy weight, it is difficult to use it for packaging things such as dogs.
Moreover, there was also the drawback that the air cap part was extremely bulky.
そこで、この考案においては容器成形も可能なほか、機

いる。Therefore, in addition to being able to be formed into containers, this idea also makes use of the cushioning properties of the bulging ribs to make it suitable for storing products with functional parts, while increasing rigidity to create a laminate that is highly self-supporting and easy to maintain its shape. The structure is characterized by laminating a polystyrene resin foam sheet on the base side of a transparent i-impact polystyrene sheet with many bulging ribs formed thereon.
次いで、この考案の実施態様について図を参照しながら
以下に例示する。Next, embodiments of this invention will be illustrated below with reference to the drawings.

−無水マレイン酸共重合体またはこれとその他の熱可塑
性樹脂とのブレンド品からなる場合とがある。1 is a transparent high-impact polystyrene sheet with a large number of bulging ribs 2 forming air pockets 1; 3 is a foamed sheet made of polystyrene resin laminated on the base side of the sheet 1; , a styrene-maleic anhydride copolymer, or a blend of this and other thermoplastic resins.
そしてノ・イインパクトポリスチレンシート１との積層
手段としては熱融着が最も好ましい。The most preferable method for laminating the sheet with the no-impact polystyrene sheet 1 is thermal fusion.

ンにて形成されている。When the above-mentioned foam sheet 3 is made of a styrene-maleic anhydride copolymer, it is formed with a styrene-maleic anhydride copolymer of 2 to 25% by weight and 98 to 5% by weight of maleic anhydride. Blends of polymers and other thermoplastic resins (such as polybutadiene) are also made of styrene containing 2 to 25% by weight of maleic anhydride.

る。This invention is constructed as described above, and the sheet formed with numerous bulging ribs 2 with air pockets 1 is made of a transparent high-impact polystyrene sheet 1 instead of a sheet with low rigidity like conventional products. Therefore, it has high rigidity and high self-supporting properties, and the foamed sheet 3 of polystyrene resin laminated on the base side of the sheet 1 makes it possible to form a laminate with even greater rigidity and excellent self-supporting properties. Since the shape of the laminate is easily maintained and the foam sheet 3 itself has a large cushioning property, sufficient cushioning property can be exhibited even if the bulging rib 2 is made low in volume.
また、自己支持性に優れた積層体ゆえに、成形性にも優
れ、容器への成形も可能となるほか、機能部分を有する
各種被包装物、例えば電化製品、機械類の形状に対応し
た形状に成形し得て緩衝体として形成することも至極簡
単になる。In addition, because the laminate has excellent self-supporting properties, it has excellent moldability and can be molded into containers, as well as shapes that correspond to the shapes of various packaged items with functional parts, such as electrical appliances and machinery. It is also extremely easy to mold and form a cushioning body.
しかも透明なハイインパクトポリスチレンシート１にて
内部を透視できる利点もある。Moreover, there is also the advantage that the inside can be seen through the transparent high-impact polystyrene sheet 1.

る。Therefore, it is possible to obtain a packaging cushioning material for egg storage containers, trays for pears, phosphorus, etc., and various articles, with a large number of bulging ribs 2 that serve as air pockets, and the bulging ribs are made of high-impact polystyrene sheets. In addition, the strength is greater than that of conventional products, and it is possible to provide an excellent product that has a double buffering effect of the cushioning properties of the bulging ribs 2 and the cushioning properties of the foam sheet 3.
