The Application Forms And Application Fields Of Stretch Film Are Very Wide

Stretch films generally add viscous additives, such as PIB masterbatch, to the PE film. It is processed by dao over-casting. The surface is slightly sticky and can stick to itself and to itself. It is mainly used to wrap and wrap objects and play a fixed role.

The stretched film will be affected by the temperature of the cooling roll during the production process. The temperature of the cooling roll increases, and the yield strength is high, but the rest of the performance decreases, so the temperature of the cooling I roll is generally controlled at 20 ℃ ~ 30 ℃. The tension of the casting line affects the flatness and winding tightness of the stretched film. If PIB or its masterbatch is used as the adhesive layer, it also affects the migration of PIB and reduces the viscosity of the stretched film. The tension is generally not more than 10kg, too much stress remains in the film roll, which reduces the elongation and other properties, and easily causes film breakage.

The application form of stretch film and the application field of stretch film are mainly used in conjunction with pallets to package scattered commodities instead of small containers. Because it can reduce the transportation and packaging cost of bulk goods by more than 30%, it is used in the integrated packaging of hardware, minerals, chemicals, food, machinery and other products; in the field of warehouse storage, stretch film is also widely used abroad. Pallet packaging for three-dimensional storage and transportation to save space and occupation.
