PE is a short form of polyethylene, a thermoplastic resin made by the polymerization of ethylene. The PE bags we Commonly used is bottom sealed.First the film is blown through the machine,and then to bag machine to cut it into bags .
PE bags are often used in packaging for small parts, and the exact sizes need to be customized according to the size of the product.
PE is odourless, non-toxic, feeling like wax, haing good low temperature resistance, low temperature to - 70 ~ 100 ℃. And its chemical stability is good, most of acid and alkali erosion,room temperature does not dissolve in solvents, small water imbibition, good electrical insulating performance and is suitable for various industries of packaging, mainly on thescratch-resistant flowers, pollution prevention function.
Bubble bag is mainly made from high-pressure polyethylene bubble film. First step is cutting film processing,and slicing the it to the size orded, last step is bag production and processing through professional machine.
Bubble bag is mainly used in buffer packaging of electronic products, plastic products, metal products,ceramic products,glass products and any products needing it.
The stretch film is also named heat-shrinkable film used for the sale and transportation of various products. Its main function is to stabilize、cover and protect products. The contraction membrane must have high puncture resistance and good shrinkage.
PVC film has the characteristics of high transparency, good gloss and high shrinkage rate. The top layer of PVC film is lacquer, the main component in the middle is polyvinyl chloride, and the lower layer is the back coating adhesive.
The low input and high yield of PVC film makes it popular and widely used synthetic material in the world. It is often used in the internal packaging of products and the fixation of large goods.
Styrofoam is a polymer material with a large number of bubbles in it. It can also be said to be a composite plastic filled with gas.
Compared with pure plastic, it has many excellent properties, such as light weight, high strength, absorbing impact load, insulation and sound insulation,etc.
Styrofoam is usually used in the packaging of light fixtures, electronic appliances, handicrafts and other fragile objects. It can cushion the impact of external impact and protect packaging products.
5.Polyethylene foam cotton
Polyethylene foam cotton is also called EPE pearl cotton, is produced by low density polyethylene fat by the physical foaming of numerous independent bubble of crosslinking obturator structure material.
It is a new type of environmentally friendly packaging materials.
