Provided is a paper container for foods capable of being fabricated by heat sealing which does not absorb flavors, such as limonene, and capable of storing a long period at ordinary temperature. The laminated material for paper containers is composed of paper substrate layer/adhesive for paper layer/first adhesive for barrier layer/barrier layer/second adhesive for barrier layer/heat-sealable PET resin layer, has an oxygen gas barrier ability of 2.0 ml/m&#xb7;D&#xb7;atm or less, and the heat-sealable PET resin layer is made having a crystal portion of less than 15%, non-crystal portion of 85% or more.

Laminated material for paper containers and paper containers using it

This invention provides a food container which can be manufactured cheaply by using inexpensive general PET resin or further inexpensive PET resin for fiber or recovered PET flakes, and nevertheless, which has a high heat resistance up to 250&#xb0; C., and the container is obtained by adding a chain extender and a compatibilizer and talc to PET resin, charging the mixture into an extruderhaving two or more vent holes, degassing under a condition where the PET resin is melted with heating by sucking at a high vacuum of &#x2212;99.99 kPa or lower from the vent holes, thereafter, forming a sheet by extrusion molding, pressure-forming with vacuum the sheet by a thermoforming machine, forming the container by keeping in a mold at 100-220&#xb0; C. The container has a total of the content of crystal portion represented by the following formula and the content of talc being 25% by weight or more.
