The mini blown film machine adopts Taiwan design barrel and screw made of Bimetal material that has been treated under high temperature for seven days, making it incredibly durable and able to run for extended periods of time. The screw is based on designs from Taiwan, with thoughtfully-crafted feeding and mixing components that boost the blown film machine's quality and production output. This model is ideal for creating plastic films such as HDPE and biodegradable materials, making it perfect for producing plastic shopping bag film.
