What are the packaging forms of transparent stretch film?
The transparent stretch film uses the film’s super winding force and retraction to bind the product compactly and fixedly into a unit, so that the scattered small pieces become a whole, even in unfavorable environments, there is no looseness or separation of the product. It does not have sharp edges and stickiness to avoid damage. Transparent stretch film was the first to use PVC as the substrate in China, and the later developed substrate now uses LLDPE as the formulation, as well as metallocene and tackifier.
Good quality stretch film has the characteristics of high transparency, high longitudinal elongation, high transverse tear strength, and good puncture performance. Stretch film is widely used. It is mainly used in conjunction with pallets to package bulk commodities instead of small containers. Because it can reduce the cost of bulk cargo transportation and packaging, it is widely used in chemical, pharmaceutical, food, machinery and other product packaging; in the field of warehousing and logistics, stretch stretch film pallets are often used abroad for three-dimensional storage and transportation. , Saving space and occupying land.
