The machine winding film is mainly made of linear low-density polyethylene (LLDPE) as the main raw material, and is produced into a multi-layer composite structure through co extrusion blow molding technology. This structure enhances puncture resistance and tensile strength while maintaining the thinness of the film through cross-linking of different molecular chains. Its thickness is usually controlled between 0.015mm and 0.03mm to ensure tight wrapping and avoid material waste. Taking a thickness of 0.02mm as an example, this specification can withstand 150% tensile deformation, which means that the length can be extended to 2.5 times the original length without breaking. This feature allows it to adapt to the packaging needs of goods with different shapes.

The core functions of materials include high toughness, tensile resistance, surface protection, and moisture and dust resistance. In logistics transportation, goods need to go through multiple loading and unloading and long-distance bumps. The 150% stretch of the film ensures that the wrapping layer is always tightly attached to the goods, avoiding the risk of loose packages. Its white surface can effectively reflect ultraviolet rays, reducing the aging problem of goods caused by light exposure. In addition, the microporous structure of the film can block dust and water vapor, making it suitable for packaging environmentally sensitive goods such as electronic products, food, and chemical raw materials. A specification design with a width of 500mm can cover the packaging needs of most standard pallets and improve packaging efficiency.
