Embodiment Construction

[0018] A method for adding a sealing reinforcing strip in the production process of an organ zipper bag provided by the present invention is characterized in that it comprises the following steps:

[0019] A. Cut the printed flat plastic film from the middle with a cutter to form the front and rear flat plastic films. The front and rear flat plastic films are respectively conveyed by two sets of conveying guide rollers, one of which sets the front flat plastic film The film is turned over so that the patterned side is facing down and sent to the heat-sealing knife holder;

[0020] B. Fold the two sides of the printed side plastic film in half to form the left and right accordion surfaces. In order to facilitate the next process, the folded left and right accordion surfaces are still connected as a whole without being cut;

[0021] C. Place the connected left and right organ surfaces step by step from the side to the top of the front plane plastic film at a distance of one bag ...

Abstract

The invention discloses a method, which can improve the bonding strength of a bag, is suitable for mass production and is applied in adding sealing reinforcement strips in the process of manufacturing an organ zipper bag. In the method, a plastic film on the front plane, the front ends of a left organ surface and a right organ surface and the sealing reinforcement strips are firstly heat-sealed together, and then concave and convex embedding zippers, the sealing reinforcement strips and a plastic film on the rear plane are heat-sealed once, so that the organ zipper bag with the sealing reinforcing rib can be simply and conveniently produced, the sealing performance of the bag is enhanced, the processing procedure for producing the whole bag is also reduced, the production cost is saved and the method is suitable for large-scale production.

Description

technical field [0001] The invention relates to a method for making a packaging bag, in particular to a method for adding sealing reinforcement strips in the process of making an organ zipper bag. Background technique [0002] At present, in a side organ zipper bag seen on the market, the organ is folded back before extending to the position of the zipper, which reduces the inner space of the bag, and there are two dead angles at the left and right organ. The reason why the organ has to be turned back halfway is because the key technical problem that the airtightness of the bag decreases after the organ extends to the zipper cannot be solved. Because if only relying on the heat-compression bonding between the zipper and the bag body and the side organ, and the strength of the zipper material itself is not high, this heat-sealing strength is not enough, so during use, due to the heat between the zipper and the bag If the sealing strength is not enough, there will be air lea...
