Claims

[Claims for Utility Model Registration] 1. Consists of a laminated resin sheet of resin layers each having a surface resin layer having thermal adhesive properties and a reinforcing resin layer, and each resin layer is entirely a non-oriented resin layer. The laminated resin sheet is deep drawn so that the surface resin layer of the laminated resin sheet becomes the inner peripheral surface layer of the concave portion, and
A deep-drawn product characterized by having slight heat shrinkage properties. 2. A deep-drawn body according to claim 1 of the utility model registration in which a predetermined filler is accommodated in a concave portion, and an opening of the deep-drawn body is closed, and the periphery of the opening is thermally bonded. In the sealed package, the lid material is formed of a laminated sheet comprising a thermal bonding resin layer and a reinforcing resin layer, and the lid material is fixed at the depth. A thermally bonded portion between the deep drawn body and the lid material at the periphery of the opening of the drawn body is formed between the surface resin layer of the deep drawn body and the thermal bonding resin layer of the lid material. The sealed package is characterized in that the deep-drawn body is slightly compressed by heating and is lightly fitted to the filling material housed in the concave portion. 3 In the sealed package set forth in Claim 2 of Claims for Utility Model Registration, the thermally bonded portion between the deep-drawn body and the lid material at the periphery of the opening of the deep-drawn body is made of a mixed resin of polyethylene resin and polypropylene resin. layer, a polyethylene resin layer, a polypropylene resin layer,
A mixed resin layer of polyethylene resin and polypropylene resin, a mixed resin layer of polyethylene resin and ethylene-vinyl alcohol copolymer resin, a mixed resin layer of polypropylene resin and ethylene-vinyl alcohol copolymer resin, or a mixed resin layer of polyethylene resin and ethylene-vinyl alcohol copolymer resin. A sealed package formed between a mixed resin layer of polypropylene resin and ethylene-vinyl alcohol copolymer resin.
