[0001] The application relates to the technical field of plastic bag production, in particular to a plastic bag recycling and melting device. BACKGROUND
[0002] Plastic bags are bags made of thin and flammable plastic film and are used to contain other objects, commonly seen in supermarkets, traditional markets, department stores, warehouses, landfills and the like, and are essential items in people's daily life. However, they have a very long degradation period and are difficult to dispose of.
