Abstract

The invention discloses a hot pressing technology for manufacturing a double-layer kraft paper leakage-proof garbage bag without glue. The hot pressing technology comprises the steps that firstly, lamination is conducted; 2, mold heating is conducted; 3, pressurizing and bonding are conducted; and 4, cooling and molding are conducted; By means of the hot pressing technology, the paper surface can be waterproof through a plastic lamination layer of kraft paper, meanwhile, the plastic lamination layer on the surface of the kraft paper can play a role in adhesion after being heated, the plastic lamination layer on the surface of the kraft paper can be heated and liquefied when a mold is in contact with the kraft paper by heating the mold, glue adhesion is effectively replaced by a hot-pressing sealing technology, and environmental protection is better realized.

Description

technical field [0001] The invention relates to the technical field of garbage bags, in particular to a hot-pressing technology for making double-layer kraft paper leak-proof garbage bags without glue. Background technique [0002] Garbage bag, as the name suggests, is a bag for garbage.
