PVC hot heat shrink film blowing machine

USAGE
This machine is using PVC powder as resin by the use of membrane technology to blow the specific PVC heat shrinkable film.
This kind PVC heat shrink film is blowing with the technology of vertical-blown method, and has the water heating system as it's film heater, which is replacing the old style electric heating system. This can make the film have those advantages: Transparent, luster, toughness, clean and also cheap cost.
With these advantages, this kind PVC heat shrink film now is widely used, for packaging of food, beverage, tea, glass products, handicrafts, sanitary wares, cosmetics, electronic products, and so on, with printing, it's also used as label for products.

FEATURES
1 The main units of this machine includes vertical extruder, take-up frame, nose installations, towing equipment, cooling equipment, heat expansion devices, winding devices, heating systems and electronic control devices.
2 As the key parts, the screw and barrel adopt 38GrMoAIA high quality alloy steel, which was finished ammonification, has the advantage of high hardness, wear resistance, corrosion resistance and long life.
3 Using new screw diameter ratio: 23: 1, which is more suitable for high melt viscosity, thermal stability, raw materials plastination.
4 With automatic temperature control system which control the heaters and cooling fan fuselage, can make sure the plastination process with constant temperature throughout, ensure the high quality film blow out.
5 Model die head, wind Central adopt nowadays newest and most suitable structure, is good for the plastination and cooling requirement.
6 The whole machine is easy to operate, has compact structure, also centralized control, and has high degree of automation.
