Heat-sealing treatment process for paper-plastic composite bag

Abstract

The invention relates to a heat-sealing treatment process for a paper-plastic composite bag. The process is characterized in that a heat-sealing treatment device for the paper-plastic composite bag isprovided, wherein the heat-sealing treatment device comprises an installation frame, a gluing device, a heat-sealing device and a cutting mechanism; a conveying channel is installed in the middle ofthe installation frame; the gluing device is installed at the left end of the installation frame; the heat-sealing device is installed in the middle of the installation frame; the cutting mechanism isinstalled at the right end of the installation frame; the conveying channel, the gluing device, the heat-sealing device and the cutting mechanism are positioned on the same horizontal line; and the heat-sealing device is in transmission connection with the cutting mechanism through a chain. The process can solve the problems that the existing composite paper which is used for manufacturing the paper-plastic composite bag and is compounded by plastic and kraft paper is finished by one production line in a plurality of steps in the production process including the processes of gluing, edge sealing, hot pressing, cooling, cutting, forming and the like, the process needs more manpower, the required production time is longer, the production efficiency is reduced, and the automatic production degree is low.

Description

technical field [0001] The invention relates to the field of paper-plastic composite bag processing, in particular to a paper-plastic composite bag heat-sealing process. Background technique [0002] The paper-plastic composite bag is composed of plastic and kraft paper. Usually, the plastic layer is made of flat wire woven cloth based on polypropylene PP or polyethylene PE. Nice features. It is one of the most popular packaging materials and is widely used in plastic raw materials, cement, feed, chemical, fertilizer and other industries. [0003] At present, the composite paper used to make paper-plastic composite bags is composed of plastic and kraft paper. In its production process, it is completed by a production line in multiple steps, from gluing, edge sealing, hot pressing, cooling, cutting and forming, etc. The completion of multiple processes requires more manpower and longer production time, resulting in a decrease in production efficiency and a low degree of aut...
