The benefits of PVC shrink wrap during transportation

PVC shrink wrap is mainly designed using the principle of stretching orientation of the molecular chain of the high fetch material, the physical principle is that when the ionomer is in a highly elastic state, it is stretched orientation, when the polymer is cooled to below the vitrification temperature, the molecular orientation is frozen, this time for the packaging of the goods, due to the relaxation of molecular stress,the molecules will be restored to their original state, resulting in shrinkage.

The biggest use of shrink film is to reduce the degree of damage to the product and packaging in transportation, or even in the transportation will not produce damage. Whether the product is packaged or unpackaged, in the process of transportation, handling, may be subject to collision or damage, this damage, it is called transportation damage. Transportation damage is a product in the transportation process of a loss, but can not be avoided, but the birth of the PVC shrink wrap so that this kind of damage has produced zero possibility.

PVC shrink wrap can be compactly packaged together, whether in the railroad trucking process or in the road transport, these collisions on the product will no longer have a great impact. pvc shrink film in the vibration of the goods play the role of buffer, thus reducing the possibility of transportation damage.
