What Are The Advantages Of Stretch Film in Packaging?

The good viscosity of the stretch film and the adhesion of the packaging film to the outside of the goods make the goods firm and play a role in fixing, dustproof and moisture-proof. It is widely used in the field of commodity production and circulation. It is used with pallets to pack bulk goods, not small containers. Stretch film packaging can reduce bulk cargo shipping and packaging costs by more than 30%. Stretch film is widely used in complete packaging of hardware, minerals, chemicals, medicine, food, machinery and other products. In the field of warehousing, the use of stretch film pallet packaging is more often used for three-dimensional storage and transportation to save space and land.

Stretch film is characterized by wrapping one or more solid objects with thin flexible packaging materials (such as cellophane, plastic molds, various mucous membrane composite films, etc.), which can not only improve production efficiency, but also prevent damage to goods during transportation , play the role of dust, moisture and cleaning. Stretch film does not require heat shrinkage during the packaging process, which is conducive to saving energy, reducing packaging costs, facilitating containerization and transportation, and improving logistics efficiency. The "integrated loading and unloading" method combining pallets and forklifts reduces transportation costs. At the same time, it is easy to identify packaged items, with high transparency, reducing distribution errors.

Due to the narrow and long flow channel and fast flow rate, the melt temperature range is generally controlled at 250°C~280°C, the casting cooling roll temperature is controlled at 20°C~30°C, and the winding tension is generally within 10kg, which facilitates the migration of the viscous agent. , reduce the internal stress of the finished film. Stretch film has a wide range of applications in many fields. Mainly used for kits of bulk cargo, not small containers.
