Background The folding and heat sealing of the bubble bag are two key steps in the bag making and forming process, and the tightness, strength and appearance quality of the bag body are directly determined. The hemming process is generally completed by a series of precise guide rollers and folders, and edges on two sides of the tiled bubble film are folded inwards and flattened to form a neat double-layer or multi-layer edge wing structure, which not only can eliminate burrs and enhance the tearing resistance of the bag edge, but also provides a flat lap surface for subsequent heat sealing. The heat sealing is performed at a specific position after edge folding, a heating element (such as a hot knife, a hot seal or a pulse heating element) is used for applying specific temperature and pressure to the laminated multi-layer bubble film, so that the surface layers of thermoplastic inner films such as Polyethylene (PE) are melted and mutually fused, and a firm sealing weld joint is formed after cooling. Modern automatic bag making machine integrates edge folding and heat sealing into a continuous production line, and ensures accurate sealing position, consistent strength and smooth appearance by positioning a photoelectric sensor and controlling heat sealing temperature and time through a PLC. The process is a core technical link for realizing dampproof, leak-proof and bearing functions of the bubble bag, and the efficient and stable flanging heat sealing system is important for improving the production speed and the product qualification rate.
