PVC-shrink film blowing machine
DETAILS

Usage:
The machine is suitable for PVC resin by the use of membrane technology blown film forming product specifications heat shrinkable film, and the film have the advantage of transparent film and good glossiness. The machine has a higher rate of contraction in the advantage of popular new packging materials, and it is widely used on packaging of food, beverage, tea, glass products, handicrafts, sanity wares, cosmetics, electronic products and so on.
 
Features:
1 the unit is mainly composed of the plastic extruder, the wind central, nose installations, towing equipment, cooling equipment, heat expasion devicesm heating systems and electronic control devices.
2 key parts, screw and barrel adopt 38CrMoAIA 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, heating stable.
4 configuration, automatic temperature control system controls the heater and cooling fan airframe so that the temperature constant throughout the process of plastination, accurate and consistent with the film production process requirements to ensure that the hot film to achieve outstanding collection of quality.
5 model head, wind central adopts special structure and it is good for plastination and cooling requirment.
6 easy to operate: compact structure , centralized control, a higher degree of automation.
7 Width from 400mm to 1500mm.
