Abstract

A five-layer structure air packaging bag and its manufacturing method, the packaging bag includes two upper and lower thermoplastic film layers, two middle layers of one-way valve film layers and a functional film layer, which are bent and heat-sealed to form It is used to accommodate the storage space for the items to be packaged. The upper and lower layers of thermoplastic film and two layers of one-way valve film are heat-sealed and bent to form an air package. The air package includes multiple independent sealed air chambers and single Each sealed air chamber is connected to the air intake channel through a one-way valve, wherein the functional film layer is connected to the air packaging body by heat sealing and is arranged on the outer side of the lower thermoplastic film layer so as to be located on the two layers The outside or inside of the thermoplastic film layer is the outer bag layer or inner bag layer of the air-packing bag, wherein the multiple independent sealed air chambers formed by the two thermoplastic film layers are used to provide air cushioning, and the functional film layer Used to provide accessibility features.

Description

technical field [0001] The invention relates to an air-packing bag and its manufacturing method, in particular to a five-layer air-packing bag designed and produced by the technology of self-adhesive air rejection and its manufacturing method. Background technique [0002] At present, the trend of globalization has increased the transportation distance of products from the place of production to the place of consumption, resulting in the rapid development of the demand for protective packaging during transportation. Traditional expanded polystyrene (EPS) and polyethylene foam (EPE) products must be foamed or processed by the manufacturer before they can be transported to users. The molded foam is bulky and very inconvenient to transport and warehousing. The on-site foaming materials developed for the convenience of transportation mainly use polyurethane foam plastic products to expand next to the contents and form a protective model. However, the price of the material is re...
