zipper bag film making machine is suit for PVC resin by the use of membrane technology Blown Film Forming product specifications heat shrinkable film,the film have the advantage: a transparent film, and glossiness-kai.The machiney has  a higher rate of contraction in the advantages of today's popular new packaging materials, widely used in packaging of the food, beverage, tea, glass products , handicrafts, sanitary wares, cosmetics, electronic products, and so on .

Featuress :

1. the unit mainly by the plastics extruder, the wind Central, nose installations, towing equipment, cooling equipment, heat expansion devices, winding devices, heating systems and electronic control devices composition.

2. Key parts screw and barrel adopt 38GrMoAIA quality alloy steel, finished ammonification, high hardness, wear resistance, corrosion resistance and other properties;

3. Using new screw, 1:23 diameter, and suitable for high melt viscosity, thermal stability is polyvinyl chloride (PVC) plastics and plasticizer for mixing, plastic superior level.

4. Automatic temperature control system configuration control the heater and cooling fan fuselage, plastination process of constant temperature throughout, accurate and consistent with film production technology requirements to ensure that the film reached fever resumption outstanding quality;

5. model head , wind Central adopt special structure, and is good for  plastination and cooling requirements

6. Easy to operate, compact structure, centralized control, a higher degree of automation
