This Taiwan design high speed blown film machine (with single rewinder) boasts a bimetal barrel and screw, which have been heat-treated for 7 days, making them highly durable and able to run for extended periods of time. Additionally, its screw designed by Taiwan engineers and its feeding and mixing parts are specially designed to boost the film quality and output. With a fixed die head and single rewinder, it is suitable for producing HDPE, Fillter, LDPE and biodegradable plastic film.

This high speed blown film machine provides a large quantity of output and a consistently high quality over a long period of time.

Gearbox 1. Functions: reduces speed of transmission
2. Speed rate: 10:1
3. High strength hard gearbox boasting service life
4. Transferring requires lubrication oil.
5. Low noise and longer service life

Heater 1. Ceramic heater heats up faster than stainless-steel alternatives
2. Its lifespan is no less than 5 years
3. It can better retain heat, resulting in lower power consumption
4. Made from high-quality ceramic and heating wire.

Fixed Die Head (Taiwan Design) 1. Made from #45 steel, providing robust performance.
2. Surface treatment is employed to increase the transparency of films.
3. The size of die heads is larger than normal, resulting in increased efficiency and productivity.

Fast Screen Changer 1. Ensure that workers are employed efficiently
2. Minimize the risk of material leak
3. Easy to change the filters, saving time and human labor

Double Vent Air Ring 1.Using two lips instead of one can cool the film more quickly, thereby increasing the machine's output.
2.Suitable for HDPE and LDPE films.

Electric Parts (Omron temperature controller and LS inverter) 1. Digital technology provides precise temperature control at a three centigrade level
