Product Description

plastic blown film machine for hdpe ldpe bags

Characteristic
The High speed film blowing machine's extruder, cylinder and screw are made of superior alloy steel that have been nitrified and precision machining. Hence it is sound in hardness, durable in corrosion resistance. The specially-designed screw is sound of quality in plasticizing, which helps increase the production capacity.

Uses
The High speed film blowing machine is applied to blowing the plastic films like low density polygene (LDPE), high density polygene (HDPE) and linear low density polygene (LLDPE). It is widely applied to producing the packing bags for foodstuff, clothing, rubbish bag and vest bags etc.
