Insulation paper container for multi-layer sheet, insulation paper containers, and a method of manufacturing

摘要

PROBLEM TO BE SOLVED: To provide a multilayer sheet for a heat-insulation paper container, which allows formation of a heat-insulation paper container exhibiting a sharp print and a beautiful surface and having excellent scratch resistance and hygienic property, and which is excellent in low-temperature heat seal property.;SOLUTION: The multilayer sheet for a heat-insulation paper container includes a low melting point thermoplastic resin layer, a print layer, a foamable low melting point thermoplastic resin layer, a paper base material, (a barrier layer if desired) and a thermoplastic resin layer. The production method of the multilayer sheet for a heat-insulation paper container includes a step of melting and applying a low melting point thermoplastic resin on a surface of a print layer of a multilayer sheet including the print layer, a foamable low melting point thermoplastic resin layer, a paper base and a thermoplastic resin layer. A heat-insulation paper container is disclosed, which includes a member (a barrel member and/or a bottom member) formed of the above multilayer sheet for a heat-insulation paper container; and a production method of the heat-insulation paper container is also disclosed.;COPYRIGHT: (C)2014,JPO&INPIT
