FAQ

Stretch film is a new type of packaging material in the logistics industry. It uses imported resin and advanced flow film extrusion production technology, which makes our product packaging more convenient. Stretch film has good tensile properties, tear resistance, strong penetration resistance, high transparency, good self-adhesiveness and high retraction rate, tight packaging and no looseness. Nowadays, the market is getting bigger and bigger. Many users can’t tell the difference between the stretch film and the shrink film. Today, the technicians from Shenzhen Zhanhui manufacturers will introduce you:

 

First, shrink film

Shrink film is used for the sale and delivery of various commodities, the main effect of which is to stabilize, conceal and maintain goods. Shrink film is used in the sale and delivery of various commodities. Its main effect is to stabilize, conceal and maintain goods. It is necessary for the shrink film to have high puncture resistance, good shortening and a certain shortening stress. In the shortening process, the film cannot be filled with holes. Since shrink film is often suitable for outdoor use, it is required to add a UV anti-UV agent.

 

Second, stretch film

It is produced by using imported linear polyethylene LLDPE resin and tackifier special additive. The earliest use of PVC as the substrate in China, DOA is a plasticizer and a self-adhesive effect to produce a PVC surrounding film. From the single layer to the second and third layers; now the LLDPE stretch film is mainly produced by the casting method, and the early LLDPE stretch film is mostly blown film. This is because the production of the casting line has the advantages of uniform thickness and high transparency, and can be applied to the requirement of high-rate pre-stretching. Since the single-layer casting can not achieve single-sided adhesion, the application field is limited, and the high-quality stretch film should have the characteristics of high transparency, high longitudinal elongation, high yield point, high transverse tear strength and good puncture performance.

 

Third, the difference

 

In terms of tensile strength and strength, the stretched film can better adapt to the geometric packaging of the product and avoid damage to the product. The stretched film also has good functions of dustproof, rainproof, etc., and is used for the purpose of distinguishing the stretched film and the shrink film function for the packaged article. High-performance resins and accessories can be used to meet the needs of different users.

With the rise of all walks of life, PE stretch film has been well used in the logistics industry. PE stretch film refers to a packaging material used in packaging and packaging. In the logistics industry, it is often used more often, mainly in environmental protection, easy to use, and not easy to fall off. So what are the benefits of PE stretch film as a packaging material?

1. The PE stretch film method is selected according to the characteristics and application range of different types of stretched film, and the stretched film is stretched to the tray goods according to the preset stretch ratio, and the advantage is that the film is stretched. Uniform, beautiful packaging, adaptability (ultra-light, ultra-high cargo can be used), and under the same conditions, the resistive stretch type saves 3050% of the consumables, so that the stretch film is actively pulled out at a slower speed than the palletized goods. speed.

2. The PE stretch film is developed from a single layer to a second layer and a third layer. Currently, a PE stretch film is mainly produced by a casting method. The PE stretch film is a very tough material and is not easily crushed by a conventional plastic pulverizer. Because the PE film is soft and tough, it is not easy to shred, not to mention the high temperature of the tool at high speed, which will cause the LDPE to melt and adhere to the blade. PE granulation can be directly put into the extruder feeding port, and the PE film is dragged into the barrel by the shearing force of the screw to heat, melt and extrude the granule.

3, PE stretch film in the production and sales process does not count product quality, performance, service life, etc., and desperately make a fuss about the price, has appeared serious vicious competition, greatly hindered high performance, high level PE stretch film The development of technology has an adverse impact on the development of the stretch film market.

The advantages of the above PE stretch film as a packaging material have been shared here. In our daily life, PE stretch film is very common. In the transportation of products from all walks of life, you can see the stretch film. The product has a good protection effect in the transportation process, and can avoid the collision and the like in the transportation of the product. In the stretch film industry, the PE stretch film is the most stretched film for the transportation of the major products.
