Title:
PAPER CONTAINER
Document Type and Number:
Japanese Patent JPH1071662
Kind Code:
A
Abstract:

To recycle paper by a method wherein the paper is enabled to be easily peeled off from an Al foil only by dipping a paper container in alkali aqueous solution.

A paper container is made of a laminate wherein a PO resin layer 11/paper paper 12/alkali soluble resin 13/a gas barrier layer 14/a PET film 15/the PO resin layer 11/a PO film 11a (inner surface) are laminated in this order. Since the paper 12 and the gas barrier layer 14 are easily separated from each other by dissolving the alkali soluble resin 13 only by dipping the paper container in alkali aqueous solution, the paper on which the PO resin layer is laminated, comes to be regenerated by a conventional waste paper regenerating process.
