Purpose

Making use of bottom blowing technology, this machine set is used to blow PPL, LDPE and HDPE plastic film to produce various civil and industrial packaging bags of food, clothing, textile and article of daily use, etc.

Feature

It can rotate in 360 degrees to enhance the strength and uniformity of plastic films

Both the screw and the charging barrel are made of 38 CRMOALA alloy steel through nitrogen treatment and precision machining with the optimal hardness, corrosion resistance and outstanding durability.

The die head is plated with hard chrome with a structure of screw spindle type; the extruded molten materials are well distributed and the blown film is of smooth finish; the air cooling device is of maze structure with well-proportioned air volume. It adopts circulating water cooling method to reach the best transparency of the film.

The winding unit adopts pressure friction or center winding and the torque motor to adjust to ensure the flat winding and convenient changing
