What Type Of Plastic Is Used For Shrink Wrap?

August-28,2018

Do you know the shrink wrap? And what type of plastic is used for shrink wrap?
 
Shrink packaging is one of the more advanced packaging methods. It uses the shrink film to wrap the product or package outside, after heating makes shrink film to wrap the product or package, fully displays the article appearance, increases the beauty and the product added value. At the same time, the packaged goods are well sealed, moisture-proof and pollution-proof, and can protect the goods from external impact, with a certain buffer, especially when packaging fragile goods, can prevent the containers from flying in the break. In addition, it can reduce the possibility of product disassembly and theft. Thermally shrinkable packaging has a lot of advantages, but what type of plastic is used for shrink wrap?
 What Type Of Plastic Is Used For Shrink Wrap
Actually, the commonly used material of heat shrink packing has three kinds. PE, POF and PVC. PE commonly used three kinds, namely: LDPE , HDPE and LLDPE three polyethylene monomer is the same, but in the synthesis of the polyethylene, adopted by the process conditions are different, therefore, to generate three different varieties of polyethylene, is different on the properties of three kinds of materials. PE film is a kind of toughness good material, not easy to use ordinary plastic crusher crushing. As PE film is soft and tough, it is not easy to be chopped, not to mention the high temperature of cutting tool at high speed, which will make LDPE melt and adhere to the blade .PE thermo-shrink film is widely used for the whole package of wine, can, mineral water, beverage, cloth, etc., which has good flexibility, strong resistance to impact and tear, not easy to damage, not afraid of moisture and large shrinkage.
 
The shrink film POF has the characteristics of high surface gloss, good toughness, great tearing strength, uniform thermal contraction and suitable for automatic and high-speed packaging, and is the replacement of traditional PVC heat shrinkable film. POF is the heat shrinkable film. POF is a multi-layer coextruded polyolefin heat shrinkable film. It is made by using linear low density polyethylene as the middle layer (LLDPE) and pp as the inner and outer layer through three extruders, then through special processes such as moulding and film bubble blowing.

PVC shrink film is one of the most popular synthetic materials in the world. PVC film has the characteristics of high transparency, good gloss, high shrinkage, heat resistance, toughness, ductility and so on. The top layer of the film is paint, the main component in the middle is polyvinyl chloride, the bottom layer is back to the adhesive. PVC is the most suitable material for three-dimensional surfaces. Due to its unique features of rain resistance, fire resistance, static resistance, easy molding and low investment and high yield, PVC is widely used in the building material industry and packaging industry.
