Problems solved by technology
[0002] At present, there is a kind of organ zipper bag seen on the market, the organ is not extended to the position of the zipper and then folded back, because the following technical problems have not been solved:
[0003] 1. The organ extends to the position of the zipper and is sealed with the zipper. The heat seal between the organ and the zipper is not strong enough, which may easily lead to air leakage or the zipper falling off
[0004] 2. If the organ reaches the edge of the zipper, if it is not sealed with the zipper, there will be no airtightness at the organ edge, and the bag will leak
[0005] 3. The zipper and the sealing reinforcement strip are heat-sealed, and the appearance of the bag is easy to wrinkle

Embodiment Construction
[0019] The technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative work shall fall within the protection scope of the present invention.
[0020] Such as Figure 1-Figure 2 , The embodiment of the present invention provides a method for making an organ zipper bag, including the following steps:
[0021] A: The main material is unwinding, the main material includes the front plane film 11 and the back plane film 12;
[0022] B: The front flat film 11, with its thermal cover facing upwards, runs along the lower end of the machine assembly line; the rear flat film 12, with its th...

The invention provides a production method of a bellows zippered bag. A sealing reinforced strip is arranged at the bellows position of the bellows zippered bag and is only in heat sealing with bellows but not in heat sealing with a zipper; meanwhile a zipper unreeling device sends the zipper to the position above the sealing reinforced strip and parallel to the sealing reinforced strip, but the zipper is not in heat sealing with the sealing reinforced strip. The production method can well solve the above technical problems and ensure that the exterior of the zippered bag is not apt to ruckle; compared with the bellows zippered bags in the market, the bellows zippered bags produced through the production method have the advantages of good sealing performance and high heat sealing strength. In addition, the bellows zippered bags in the market are generally produced through specific imported machines which are expensive and have high cost; however, the bellows zippered bags produced through the production method can be produced through domestic machines and thus are much cheaper in price.
Description
Technical field [0001] The invention relates to a manufacturing method of a packaging bag, in particular to a manufacturing method of an organ zipper bag. Background technique [0002] At present, a kind of organ zipper bag seen on the market, the organ folds back without extending to the position of the zipper, because the following technical problems have not been solved: [0003] 1. The organ extends to the position of the zipper and is sealed with the zipper, and the heat sealing strength of the organ and the zipper is not enough, which may cause air leakage or the zipper to fall off. [0004] 2. If the organ reaches the edge of the zipper, if it is not sealed with the zipper, the edge of the organ will not be sealed and the bag will leak. [0005] 3. The zipper and the sealing reinforcement are heat-sealed, and the appearance of the bag is easy to wrinkle. Summary of the invention [0006] The purpose of the present invention is to overcome the defects of the prior art and provid...
