High Speed Blown Film Machine with Double Rewinder

with Taiwan design extrusion screw and barrel

This Taiwan design high speed blown film machine (with double rewinder) features a bimetal barrel and screw which have been hot-treated for a duration of seven days, making it incredibly durable and allowing for long lasting operation.

The design of the screw is taken from Taiwan and the feed and mix components are exceptionally efficient, allowing for improved film quality and manufacturing output.

This film blowing machine is designed for producing plastic films like HDPE, LDPE, LLDPE, and biodegradable substances. It is the perfect machinery for the job.

The high speed blown film machine features a combination of a rotary die head and a double rewinder, is ideal for making shrink film.
