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.degree. C. and about 300.degree. C. for a short period of time.
