Wrapping film is a kind of packaging method that uses mechanical stretching device or manual force to stretch the film under normal temperature to wrap the goods tightly for transportation and storage. It is a very popular packaging form. The resin and flow film extrusion production process is adopted. It has the characteristics of good tensile property, tear resistance, strong penetration resistance, high transparency, good self-adhesion, high shrinkage rate, tight packaging and no loosening. It can be widely used for single or pallet packaging and other binding packaging of chemical raw materials, fertilizer, food, electromechanical products, light textile products, etc.

1. The winding film has a high temperature resistance of about 180 degrees. The product is non-toxic and odorless, has strong resistance to burning, and is not easy to damage. Therefore, it is widely used in various fields.

2. Good transparency and luster; It has good air tightness and fragrance retention; The moisture resistance is medium, and the moisture permeability decreases at low temperature. The film has excellent mechanical properties, its strength and toughness are the best of all thermoplastics, and its tensile strength and impact strength are much higher than ordinary films; With good stiffness and stable size, it is suitable for secondary processing such as printing and paper bags.

3. The winding film has excellent chemical resistance and oil resistance. But it is not resistant to strong alkali; It is easy to carry static electricity, and there is no proper anti-static method yet, so attention should be paid when packaging powder goods. Wrapping film is a very popular product in the logistics industry. In summer, online shopping is more popular. Many logistics industries will use it to wrap items. It will be piled up in one piece. Under strong sunlight, plus the accumulation of items, it will inevitably produce high temperature. If it can not withstand high temperature, it will cause fire or sunburn.
