Our bubble film machine uses low-density polyethylene (LDPE) as its primary raw material with a melting index (MI) of 2-7. Additionally, linear low-density polyethylene (LLDPE) with a melting index of 1.0-1.5 can be added in appropriate proportions. Recycled LDPE with a melting index equivalent to MI=2-4 can also be partially or completely used as a raw material to produce bubble film of a specific width.By utilizing these raw materials, our bubble film machine can produce high-quality bubble film with consistent thickness, excellent transparency, and superior mechanical properties. Furthermore, this method of production ensures that the bubble film is environmentally friendly, cost-effective, and durable.
