Abstract

PURPOSE: To continuously and inexpensively obtain deep-drawing molded product, such as paper cups, by a method wherein a cellulose fiber system sheet made by adding thermoplastic resin is molded by thermoforming after being preheated.
CONSTITUTION: A sheet is made by adding a fibrous or a powdery object made of 5W40wt% of thermoplastic resin (for example: polyethylene), based on fiber compound whose main ingedient is cellulose fiber, the sheet being previously heated at a temperature higher than the melting point of the thermoplastic resin. The resin is melting-adhered to the fiber compound, and then cooled. The work is molded by thermoforming at a temperature zone ranging from 40°C below the melting point of the resin to the melting point to produce a molded product. This eliminates the need for rising a temperature to higher than the melting point of the resin when molding by thermoforming, and thereby the molded product being excellent in a mold-releasing property and in the quality is obtainable.
