Stretch and wrap with PE by hand

With the development of logistics, stretch film packaging materials have been widely used. Many companies believe that stretch film is a small business and do not value its quality and performance. They believe that stretch film of any type of material can be used. There are now some problems with poor quality. The stretch film on the market breaks when pulled, which is mostly caused by improper selection of raw materials for stretch film. Therefore, when choosing stretch film, you must first look at the raw materials, which has become the main task for many users to judge the quality of stretch film when purchasing.
The stretching film has a strong shrinkage force, and after thermal shrinkage, it can effectively wrap the item to achieve the effect of protecting the item. If it is specially designed and made into a traditional plastic bag style, the packaged items can also be lifted through the two ends of the stretching film, which is more conducive to improving the speed of transportation. The stretch film is processed using extrusion technology, and its main raw materials include polyvinyl chloride (chemical formula C2H3Cl) (polyvinyl chloride), low-density (unit: g/cm3 or kg/m3) polyethylene (PE-LD), and ethylene ester ethylene copolymer.
