Method for producing a two-piece paper container
First Claim
1. A method for producing a two-piece container consisting ofblanking a container body wall member and a container bottom panel member from a base paper made of a stock containing about 10 to about 80% by weight of high-density polyethylene synthetic pulp;
- fabricating the members into a container using a conventional cup-making machine; and
then increasing the water proofness, water-repellency or stiffness by heating the so-fabricated whole container at a temperature between 120°
C. and about 300°

Abstract
A method for producing two-piece paper containers having waterproofness, water repellency, permeability and good stiffness without using any adhesive. A container body wall member and a container bottom panel member are blanked out from a base paper made from a stock containing about 10 to about 80% by weight of high-density polyethylene synthetic pulp. The blanked members are fabricated into a container using a conventional cup-making machine without using any adhesive. Then, the so-fabricated containers are heated at a temperature between about 120° C. and about 300° C. for a short period of time.
