Blown Film Extrusion

The Blown Film Extrusion process involves a film blowing machine where the cylinder and screw rods are crafted from high-quality alloy steel, nitrided, and processed meticulously to ensure exceptional hardness and resistance to corrosion.

Key features of Blown Film Extrusion equipment include:
1.Premium screw and barrel components
2.Machine speed controlled by inverter
3.Automatic temperature regulation
4.Single winder for film output
5.Compatible with materials such as LDPE, HDPE, LLDPE
6.Ideal for producing various plastic bags, including garbage bags
7.Film width ranging from 100mm to 1200mm

Blown film machines can produce films with widths from 150mm to 1200mm (5 to 48 inches), which can be tailored to meet specific customer requirements. These machines are suitable for manufacturing HDPE, LDPE, and recycled films.
