Description

Technical Field

[0001] The utility model relates to the technical field of bottom sealing devices, in particular to an automatic bottom sealing device for an environmentally friendly woven bag. Background Art

[0002] Woven bags are a type of plastic bag used for packaging. Their raw materials are generally various chemical plastic raw materials such as polyethylene and polypropylene. The main raw material produced abroad is polyethylene (PE), and the main raw material produced domestically is polypropylene (PP), which is a thermoplastic resin made by polymerization of ethylene. In industry, it also includes copolymers of ethylene and a small amount of α-olefins. Polyethylene is odorless, non-toxic, feels like wax, has excellent low-temperature resistance (the lowest operating temperature can reach -70 to -100°C), good chemical stability, can withstand the erosion of most acids and alkalis (not resistant to oxidizing acids), is insoluble in general solvents at room temperature, has low water absorption, and has excellent electrical insulation properties.

[0003] At present, most of the existing woven bags are processed by stringing ropes when sealing the edges. The sealing parts of the processed woven bags cannot be completely sealed. The woven bags themselves are plastic, and after heating, they act as hot melt adhesive to bond themselves without generating waste. Therefore, we propose an environmentally friendly woven bag automatic bottom sealing device. Utility Model Content
