As a professional production of Clear PET Shrink Wrap factory, Xiamen Guanhua Attract buyers with good quality and good price. Ordinary polyester is a crystalline polymer, and ordinary PET film can only get a thermal shrinkage rate of less than 30% after special process treatment. In order to obtain a higher thermal shrinkage polyester film, it must also be modified. In other words, in order to prepare polyester film with high thermal shrinkage, common polyester, namely polyethylene terephthalate, needs to be copolymerized. The highest thermal shrinkage rate of the copolymerized PET film can be as high as 70%.

Clear PET Shrink Wrap Features:

1. Unitization,This is one of the biggest features of shrink film packaging. With the strong winding force and retraction of the film, the product is compact and fixed into a unit, so that scattered small pieces become a whole, even in an unfavorable environment, the product does not have any loose and separation, and there is no sharp edge and viscosity, so as to avoid damage.

2. Primary protection,The primary protection provides the surface protection of the product, forming a very light and protective appearance around the product, so as to achieve the purpose of dust, oil, moisture, water and anti-theft. It is particularly important that the wrapping film packaging makes the packaging items evenly stressed to avoid damage to the items caused by uneven stress, which is the traditional packaging (bundling, packaging, tape and other packaging) can not be done.

3. Compression firmness,With the help of the retraction force after the winding film is stretched, the product is wrapped and packaged to form a compact, space-free unit as a whole, so that the pallets of the product are tightly wrapped together, which can effectively prevent the dislocation and movement of the products during transportation. At the same time, the adjustable stretching force can make the hard products close and the soft products tight. Especially in the tobacco industry and the textile industry has a unique packaging effect.

4. Cost saving,The use of winding film for product packaging can effectively reduce the cost of use, the use of winding film is only about 15% of the original box packaging, about 35% of the heat shrink film, and about 50% of the carton packaging. At the same time, it can reduce the labor intensity of workers, improve the packaging efficiency and packaging grade.
