Problems solved by technology

[0002] Heat-sealing bags are widely used in daily chemical product packaging, food and drug packaging and other fields. At present, the commonly used heat-sealing films are polyethylene films or polypropylene films. However, although polypropylene films used for heat sealing have better stiffness , Tensile strength, but when it is processed, the required heat-sealing temperature is high, resulting in high electric heat loss of the sealing equipment, and the peeling force is large, it is not easy to peel off, causing greater inconvenience in use
