Zipper doypack production process

Abstract

The invention relates to a zipper doypack production process. The zipper doypack production process comprises the following steps that S1, a packaging film is formed; S2, edge sealing is conducted, aservo bag pulling device is used for pulling a film material to be conveyed to a guiding mechanism, and after the film material is folded through the guiding mechanism, the procedures of bottom sealing, zipper sealing, zipper head sealing, vertical sealing and cold sealing are conducted in sequence; S3, cutting forming is carried out; S4, material filling is conducted, a packaging bag is subjectedto bag opening, filling and bag unfolding procedures and then subjected to sealing treatment, and an upper heat sealing device and an upper cold sealing device are adopted for conducting upper heat sealing and upper sealing opening cooling on the packaging bag in sequence; and S5, inspecting and packaging are carried out. According to the zipper doypack production process, the packaging process of molding, bag making, bag opening, metering filling and sealing of a zippered doypack can be automatically completed, the zipper doypack production process is suitable for packaging design of packaging materials of various heat-sealing multi-layer composite films, the production cost is reduced, and the production efficiency is improved.

Description

technical field [0001] The invention relates to the technical field of stand-up pouches, in particular to a production process for zipper stand-up pouches. Background technique [0002] Doypack refers to a flexible packaging bag with a horizontal support structure at the bottom, which does not rely on any support and can stand on its own regardless of whether the bag is opened or not. Stand-up pouches with zippers can also be reclosed and re-opened. Since the zipper is not closed and the closure strength is limited, this form is not suitable for packaging liquids and volatile substances. [0003] In the prior art, as the Chinese patent with publication number CN110104314A, it discloses a stand-up pouch and its preparation method, which relates to the field of packaging technology, through the bag body; the bag top, the bag top is arranged on the side of the bag body top, and the edge of the bag top is adhered to the top of the bag body; the bottom of the bag, the bottom of ...

AI Technical Summary

Problems solved by technology

[0004] The above-mentioned existing technical solutions have the following defects: Although the above-mentioned technical solutions solve the problem of the heavy weight and high transportation cost of glass bottles and pop cans in the prior art, the existing production process is for large-capacity bags, and the round hole at the bottom of the bag is easily damaged when it is dropped. , and the technical problem of making the bag lose its self-supporting effect

However, it is only a method for preparing stand-up pouches. When packaging materials, a special filling machine is required to open the stand-up pouches to fill the materials, which not only increases production costs, is time-consuming and laborious, but also reduces to a certain extent improved work efficiency
