FAQ | 3-Layer Co-Extrusion Film Blowing Machine FAQ

1. What is a three-layer co-extrusion film blowing machine?

A 3 Layer Blown Film Machine is an advanced film production equipment that uses three extruders to produce multilayer plastic films. By combining different raw materials, it provides films with high strength, excellent sealing, and diverse applications.

2. What types of films can it produce?

This machine can produce a wide range of films, including:

①Packaging films (for food, industrial goods, daily products)

②Shrink films (used in beverage, electronics, and logistics packaging)

③Stretch hood films (for pallet wrapping)

④Agricultural films (mulching films, greenhouse films)

⑤Heavy-duty bags and garbage bags

3. What are the advantages of a three-layer co-extrusion film?

Compared to single-layer film, three-layer co-extrusion film offers:

①Better mechanical strength

②Enhanced barrier properties

③Improved puncture and tear resistance

④Greater flexibility in combining materials

⑤Lower production cost by using recycled or cheaper raw materials in inner layers

4. What raw materials are suitable for this machine?

It can process LDPE, LLDPE, HDPE, mLLDPE, EVA, and recycled materials. Different material combinations allow customized performance such as transparency, toughness, or sealing ability.

5. Which industries use three-layer co-extrusion films?

These films are widely used in:

①Food packaging

②Courier and express bags

③Industrial packaging

④Agriculture

⑤Logistics and transportation
