These machines are designed to heat melt plastic granules, extrude liquid state plastic and blow plastic into different width and thickness film. 

SJ45, 50, 55 HDPE/LDPE film blowing machine 
SJ-B55、B60、B65 Rotary Die-head PE Blowing Film Machine
SJ-40X2、45X2 Double layer Co-extruding & rotary die Blowing film Machine
SJ-P40, 50, 60, 70 Polypropylene Rotary Die Blowing Film Machine

It is suitable for blowing the plastic film as high density polyethylene (HDPE), low density polyethylene (LDPE) and linear low density polyethylene (LLDPE), which is widely used for packing foodstuff, garment, textile, daily-used articles and industrial production etc. I can also produce pearl film or degradation film by adopting special raw materials.

Highlights:
1) The screw and cylinder are made of 38CrMoAl high quality alloy steel after fine finishing and nitrided treatment, which has high hardness, strong resistance to corrosion,durable service.
2) The die is plated with hard chrome, of screw mandrel type structure with even and smooth discharging, the blown film has fine finishing. The blower is of labyrinth structure with even air output.
3) The re-winding unit adopts pressure friction rewinding, which is durven by torque motor, with even and smooth rewinding and easy roll changing.

Highlights:
1) Its Die head could rotate within 360 degree angles, which could strength the indensity and evenness of plastic film.
2) The screw and cylinder are made of 38CrMoAl high quality alloy steel after fine finishing and nitrided treatment, which has high hardness, strong resistance to corrosion,durable service.
3) The die is plated with hard chrome, of screw mandrel type structure with even and smooth discharging, the blown film has fine finishing. The blower is of labyrinth structure with even air output.
The take-up unit adopts lifting type of square-frame platform structure, the height of lifting frame can be adjusted automatically according to different technologicalrequirement.
4) The re-winding unit adopts pressure friction rewinding, which is durven by torque motor, with even and smooth rewinding and easy roll changing.

It is suitable for blowing doulbe layer plastic film as low density polyethylene (LDPE) and linear low density polyethylene (LLDPE). This kind of film has multi-function, such as oxygen insulation, light insulationm oil proof, leak proof, moisture-proof and anti-frost, which could prolong the period of preservation of foodstuff, liquid packing.

Highlights:
1) The full set machine is made from to sets motors, two cylinder and one rotary die, which could togeher extrude two different plastic materials. The die can be rotate to left and right 360 degree, itcan strength the intensity and evenness of film..
2) The screw and cylinder are made of 38CrMoAl high quality alloy steel after fine finishing and nitrided treatment, which has high hardness, strong resistance to corrosion,durable service.
3) The die is plated with hard chrome, of screw mandrel type structure with even and smooth discharging, the blown film has fine finishing. The blower is of labyrinth structure with even air output.
4) The re-winding unit adopts pressure friction rewinding, which is durven by torque motor, with even and smooth rewinding and easy roll changing.

This machine is suitable for producing polypropylene (PP) film. It is widely used for packing food, garment, textile, daily articles and industrial products etc.
