1. Polyethylene bag: polyethylene, referred to as polyethylene, is a thermoplastic resin polymerized from ethylene. The common PE flat bag is to blow the film blowing machine, then cut the bag making machine into bags and seal it at the bottom.
PE bags are often used for small parts packaging, the specific size needs to be customized according to the size of the packaging products.
聚乙烯无臭,无毒,感觉像蜡一样,具有良好的耐低温,低温度- 70 ~ 100℃,化学稳定性好,大部分的酸和碱侵蚀,常温下不溶于溶剂,吸水性小,电绝缘性能好,适用于各个行业的包装,主要包装防刮花、防污染功能。
Polyethylene is odorless, nontoxic, and feels like wax. It has good low temperature resistance, low temperature - 70 ~ 100 ℃, good chemical stability, most of the acid and alkali erosion, insoluble in solvents at room temperature, small water absorption, good electrical insulation performance. It is suitable for packaging in various industries, mainly with anti scratch and anti pollution functions.
2. bubble bags
The high-pressure polyethylene foam film is mainly used to cut the foam film, cut the foam film into the required size of the foam bag, and then carry out the foam bag processing through the special foam film making machine.
It is mainly used for the logistics transportation protection of electronic products buffer packaging, plastic products, metal products, ceramic products, glass products and fine wine display shelves that need buffer protection.
3. stretch film
Stretch film, also known as heat shrinkable film, is used for the sale and transportation of various products. Its main function is to stabilize, cover and protect the product. The shrinkage film must have high wear resistance, good shrinkage and certain shrinkage stress.
PVC film has the characteristics of high transparency, good luster and high shrinkage. The top layer of PVC shrinkage film is coating, the main component in the middle is PVC, and the bottom layer is gum.
PVC film is one of the most popular and widely used synthetic materials in the world, which has the characteristics of low input and high output. It is often used for the internal packaging of products and the fixation of large goods.
4. polystyrene foam
Polystyrene foam generally refers to plastic foam plastics, which is a polymer material with plastic as its basic component and contains large amount of bubbles. Therefore, it can also be said to be a composite plastic filled with gas.
Compared with pure plastics, it has the advantages of light weight, high specific strength, shock absorption, heat insulation, sound insulation, etc.
Paulilon is generally used for fragile packaging such as lighting, electronic appliances, handicrafts, etc., which can well buffer external impact protection packaging products.
5. pearl cotton
Polyethylene foam cotton, also known as EPE pearl cotton, is a non cross-linked closed cell material composed of low density polyethylene fat and a large number of independent bubbles produced by physical foaming. It is a new type of environmental protection packaging material.
Pearl cotton is rich in color, beautiful in appearance, can effectively eliminate static electricity and ignition effect, and is often used as packing box. Moreover, it does not pollute the environment and can be recycled, which reduces the cost of product packaging to a certain extent. It is an ideal substitute for traditional packaging materials.
