Product Description

Flim blowing screw barrel

Usage:
This screw is suitable to blowing the plastic films like low density polyethylene (LDPE), high density polyethylene(HDPE) and linear low density polyethylene(LLDPE). It is widely applied to producing the packing bags for foodstuff, clothing, rubbish bag and vest ones.

Its extruder, cylinder and screw rods are made of quality alloy steel that have been nitrized and processed in a precision way. Hence it is sound in hardness, durable in corrosion resistance. The specially-designed screw is of sound quality in plasticizing, which helps increase the productino capacity. No matter what size the film is, big or small, it can achieve the best effect of cooling. It adopts independent moment to collect, the effect will be better if fit with rotate die.
