1. The type of shrink machine
There are many kinds of shrinking machines, but the ultimate result is mainly the difference in processing materials. According to the material, the shrinking machine includes: PE shrinking machine and POF, PVC shrinking machine. Its model is very similar and the principle is the same. Manufacturers need to choose the right type of shrink machine according to the customer's packaging requirements and product characteristics. The shrinking machine mainly includes three mechanisms: a heat generating mechanism, a blowing mechanism, and a conveying mechanism. These parts have interrelated factors.
2. Application of shrinking machine
Shrinking machines have a very important position in the packaging field and are used in a wide range of applications: printing, hardware, furniture, electronics, food, pharmaceuticals and other industries. The shrinking materials used in general shrink machines include PVC, POF, PE, and the like.
At present, POF shrink film is the most widely used, and its good advantage of good transparency, high shrinkage, high tenacity, and especially environmental protection has been recognized and used by a large number of manufacturers. It can also be called an environmentally friendly shrink film, which has a wide range of applications.
The chemical name of the PVC shrink film is: Polyethylene belongs to toxic materials. It is not environmentally friendly. It is less precarious and is gradually replaced by POF. PVC shrink film is generally suitable for use in chemical non-environmental protection industries.
PE shrink film is generally the most widely used in the beverage industry, characteristics: poor transparency, good will, strong pull for the product compared to heavy shrink film packaging. Suitable for large-volume automatic shrink packaging items such as cans, glass bottles, beer, and mineral water.
