Abstract

PURPOSE: To prevent the reduction of the strength at a boundary by a method wherein the thermoplastic resin film is bonded under pressure by heating for a specified time and at a specified high temperature and thereby a protuberant part is formed at the boundary between a bonded part and a nonbonded part.
CONSTITUTION: The end part 9 of an opening of a heavy packing sack made of the thermoplastic synthetic resin film 7, which is to be bonded under pressure, is put between a supporting plate 2 and a heating body 4 and bonded into one at the heating temperature of 300°CW380°C, for a pressing time of 0.3W2sec and with a pressing power of 0.5W1.0kg/cm2 approximately. The film 7 of the bonded part shrinks and the protuberant part 12 is formed resultantly at the boundary between the bonded part 10 and the nonbonded part 11, whereby the reduction of strength of the boundary part is prevented.
