Frequently Asked Questions

How is the bubble film machine produced?

Our bubble film machine uses low-density polyethylene (LDPE) as its primary raw material with a melting index (MI) of 2–7. Linear low-density polyethylene (LLDPE) with MI 1.0–1.5 can be added in appropriate proportions. Recycled LDPE with equivalent MI can also be used partially or completely.

What raw materials can be used in your machines?

LDPE (MI 2–7), LLDPE (MI 1.0–1.5), and recycled LDPE (MI 2–4) are compatible. This flexibility ensures cost-effective and environmentally friendly production.

What is the application of the plastic-free coating machine?

It is designed for 1-meter width paper, applying water-based bio-glue for food packaging, cups, bags, and trays—ideal for eco-conscious industries.

How to choose the right stretch film machine?

Consider output capacity, film width, layer configuration, and automation level. Our team provides expert guidance based on your packaging needs.

Do you offer after-sales service?

Yes, we provide comprehensive support including installation guidance, technical training, maintenance, and spare parts supply.
