Blown Film Extrusion

Blown Film Extrusion
The blown film extrusion technique utilizes a film blowing machine, designed with a cylinder and screw rods made from high-grade alloy steel that is nitrided and refined to achieve superior hardness and corrosion resistance.

Notable characteristics of blown film extrusion machinery encompass:
High-quality screw and barrel components
Inverter-controlled machine speed
Automatic temperature control
Single winder for film production
Compatibility with materials such as LDPE, HDPE, and LLDPE
Suitable for creating various types of plastic bags, including refuse bags
Film widths available from 100mm to 1200mm

Blown film machines are capable of producing films ranging from 150mm to 1200mm (5 to 48 inches) in width, allowing customization to fulfill specific client needs. These machines are appropriate for the fabrication of HDPE, LDPE, and recycled films.
