Jdpe Bubble Film Making Machine

The low density polyethylene (LDPE) with melting index MI=2~7 is used as the main raw material in the bubble film machine. The linear raw material (LLDPE) with melting index MI=1.0~1.5 can be added in proper proportion, and the regenerated LDPE with melting index equivalent to MI=2~4 can be partly or completely used as the raw material so as to make bubble film of a certain width.
Because the air bubble film, is filled with air, it is light, transparent, flexible with sound insulation, anti-vibration and anti-wear performance, which is widely used in electronic, instrumentation, ceramics, handicrafts, household appliances, bicycles, kitchens, furniture and lacquer products, glass products and precision instruments and other antiknock cushioning packaging. It can be made into bubble bags, envelope bags, etc.
