Film Blowing Machine produce Polyethylene film,LDPE film,HDPE film,LLDPE film,PVA film,PLA film,Biodegradable Film.
Blown Film Extrusion
The Blown Film Extrusion process utilizes a film blowing machine, featuring cylinders and screws constructed from high-grade alloy steel, which are nitrided and meticulously processed to achieve superior hardness and corrosion resistance.
Notable characteristics of Blown Film Extrusion equipment include:
High-quality screw and barrel components
Speed regulation through inverter control
Automatic temperature management
Single winder for film production
Compatibility with materials such as LDPE, HDPE, and LLDPE
Suitable for producing diverse plastic bags, including refuse bags
Film width options ranging from 100mm to 1200mm
Blown film machines are capable of generating films with widths between 150mm and 1200mm (5 to 48 inches), allowing customization to fulfill specific client needs. These machines are adept at manufacturing HDPE, LDPE, and recycled films.
