PP Shrink Wrap

Xiamen Guanhua is one of leading China PP Shrink Wrap manufacturers, suppliers and exporters. Xiamen Guanhua is worthy of your trust. PP Shrink Wrap is a kind of semi-crystalline material, PP is a high density, no side chain, high crystalline linear polymer, it is one of the least dense materials in all resins, the film insulation of PP material is very good, often used in electrical insulation, PP film can be very thin, widely used in furniture, architecture, because of its characteristics, PP film has advantages as furniture film, writing film, floor film and self-mucous membrane.

The PP Shrink Wrap is the use of the film in the high elastic state of the longitudinal or transverse tension of the energy stored in the film, the use of thermoplastic plastic has a memory effect on the bidirectional or unidirectional stretch before the form has, in the heat again to recover the function of the stretch before the form to achieve the purpose of packaging. The heat shrinkable film is a concrete example of the memory effect of polymers. The shrinkage of the film is determined by the tensile degree of the film during the orientation process, and the thermal shrinkage rate reflects the thermal shrinkage performance. Heating temperature and time are important factors affecting the thermal shrinkage rate. At present, there are few reports on the thermal shrinkage properties of thermal shrinkable materials. By investigating the effects of temperature and time on the shrinkage properties of several thermal shrinkable films commonly used in production, parameters can be provided for products with different packaging design, production and processing technology requirements.

PP Shrink Wrap are used in the sale and transportation of various products. Its main function is to stabilize, cover and protect the product. Shrinkage film must have high puncture resistance, good shrinkage and a certain shrinkage stress. During the shrinkage process, the film cannot create holes. Since shrink films are often suitable for outdoor use, UV anti-UV agents need to be added.

PP Shrink Wrap is a kind of shrinkable film, is widely used in commodity packaging a kind of packaging, with transparent, packed, sealed, moisture-proof and other characteristics, its process and equipment is simple, low packaging cost, packaging methods are diverse, favored by businesses and consumers, and its packaging is moving towards a more economical, more practical, more environmentally friendly direction.
