What Are The Specifications And Characteristics Of Winding Film? Reduce Freight Transportation Packaging Cost By 30%!!

Winding film is mainly used in conjunction with pallets to pack scattered goods in whole sets instead of small containers. Because it can reduce the bulk cargo transportation packaging cost more than 30%, so it is widely used in pallet packaging of goods, such as electronics, building materials, chemical, metal products, auto parts, wire and cable, daily necessities, food, paper and other industries of a variety of products on the whole set of packaging. In the field of warehouse storage, foreign countries also use winding film tray packaging for three-dimensional storage and transportation, in order to save space and occupy an area. Then, what are the specifications and characteristics of wound film? Here is the new era Xiaobian for you to answer.

Winding film, also known as stretch film, heat shrinkable film. The earliest PVC as the base material in China, DOA as a plasticizer and play a self-adhesive role, but the cost is high (relative to PE ratio is significant, less unit packaging area), tensile is poor, and with environmental problems. Nowadays, LLDPE is the main winding film, including C4, C6, C8 and metallocene PE(MPE).
At present, the maximum width of the film can be produced is 2.0-2.5m, and the maximum thickness is 60μ. The common stretch winding film is 20μ. The thinnest film is 8-10μ.

High quality stretch film has the characteristics of high transparency, high longitudinal elongation, high yield point, high transverse tear strength, good puncture performance and so on. At the same time, the material density of stretch film also affects the performance of the film. With the increase of the density, the orientation is higher, the flatness is better, the longitudinal elongation is higher, and the yield strength is higher, but the transverse tearing strength, puncture strength and light transmittance all decrease.
