Advantages of a thermoshrinkable film from a polyolefin before the PVC film:
- Environmental friendliness. Unlike PVC of films of POF the film does not contain chlorine which can thermoshrinkages will be allocated from film PVC in the course of storage, and burning of waste, negatively influencing a human body and thermoshrinkable cars.
- Economical production. The PVC films which are formed at thermoshrinkage, chlorine - containing substances are a serious problem for production since have the destroying effect on the thermoshrinkable equipment, reducing the term of its service. Use of POF of films increases productivity and reduces costs of service of the equipment.
- Wide temperature range of storage and use of a film of POF. Lack of free shrinkage. Temperature condition of storage and use of a poliolefiny film is much wider, than films from PVC. The polyolefin film remains elastic, flexible and strong even at very low temperatures (to - 400C) whereas the film of PVC becomes fragile and fragile. PVC the film is highly sensitive to influence of the increased temperatures. At increase in ambient temperature it is possible to expect process of spontaneous shrinkage from PVC of a film that in turn can bring the stored rolls of PVC of a film and impossibility of their further operation to an unsuitable state.
- Profitability. Distinction in density of materials of a film of POF and film of PVC (RPOF = 0,92 g/cm3, rPVH = 1,3 g/cm3) exerts considerable impact on the economic party of a question. The roller of a film of identical weight from more dense PVC has smaller winding (about 30% ), than POF film roller. Film material POF, actually more expensive for 1 kg, in recalculation for 1 meter turns out 15 - 20% cheaper than the PVC film.
- Strength characteristics Instead of PVC of films it is possible to use film POF with the smaller thickness since POF of a film possess excellent strength characteristics, such as durability on a puncture and a gap that adds some more percent to economy.
