摘要

Improvements introduced in the manufacture of packaging bags intended for transport under special conditions, particularly for the transport of delicate products packed with a wet material, characterized by the combination of the following operations: subjecting a band of curled paper of suitable width, to a impregnation operation with a plastic material on one of its faces; submitting this same band of curled paper provided with a coating of plastic material on its other side; subjecting, by the action of heat, this band of plasticized material on both sides to a stabilization or polymerization operation of the applied plastic material; cut the band thus treated in convenient lengths, and submit these cut pieces to manufacturing operations to obtain the finished bag.
