摘要：<p>PROBLEM TO BE SOLVED: To form a tray container which is hard to break, and for which an easy separatability with a lid member is ensured by a method wherein a laminated body of a gas barrier layer and an easily separatable layer, is bonded to one of expanded polyethylene layers with an adhesive, and at the same time, a shaping material is laminated on the other surface. SOLUTION: For an expanded polyethylene resin 1 which is used as an intermediate layer of a laminated sheet, the expansion ratio is 5 times or less, and the density is 0.15-0.85g/cc. On one surface of the expanded polyethylene resin 1, a laminated body of a gas barrier layer 3 such as an ethylene-vinylalcohol copolymer, and an easily separatable layer 4 for which the kind of a polyolefin based resin is made different from that of a lid member, is affixed with an adhesive 2. The lamination of the gas barrier layer 3 and the separatable layer 4 is performed by co-extrusion, and the laminated body comes into contact with one surface of an expanded polyolefin resin 5. On the other surface of the expanded polyethylene resin 1, a shaping material 5 of a non-draw polypropylene, is laminated with an adhesive layer 2'. A tray container is formed with the surface on which the shaping material is laminated facing outside.</p>
