The logistics chain is increasingly mechanized and automated, cargo transportation is more palletized and unitized, and e-commerce is developing rapidly, making Stretch Film a product of global transactions.
Stretch film is a kind of packaging material commonly used for packing things, also called stretch film. It is produced with LLDPE as the main raw material and added with tackifier. Stretch film has the characteristics of strong tensile strength, strong puncture resistance, and strong self-adhesiveness. Colored Stretch Film can be divided into various colors, types, and specifications can be customized. It can prevent moisture, dust, and damage during use. . It is suitable for products in various industries, and is widely used in packaging series of chemical products, electronic product boxes, ceramic products, electromechanical equipment and various foreign trade export products. Stretch films generally include hand stretch film, Machine Stretch Film (added with metallocene), and pre-stretched stretch film. The stretch film produced by Dongfang Sun has good viscosity, strong stretching force and supports customization. The manual stretching film is mainly packaged by hand. The stretching film is generally 500 mm wide and weighs 4 to 5 kg per roll to facilitate the operation. Machine Stretch Film adopts the mechanical packaging method, which mainly relies on the movement of the goods to drive the film rolls for packaging. The requirements for the tensile strength of the film are relatively high, and there are also certain requirements for the stretch rate of the film. The general stretching requirement is 300 %, the roll weight of the product is 15kg.
Pre-stretched stretch film is mainly used in mechanical packaging. When packing, the packaging machine first stretches the stretch film to a certain ratio and then wraps the stretch film on the goods to be packaged. Depending on the resilience of the film, the goods are compressed and packaged. High quality requirements, high tensile strength, elongation and puncture resistance. In addition to transparent or milky white, Stretch Film has a variety of colors, including blue, yellow, red, black, pink, and green. They are used to package goods to distinguish products, so as to better identify goods classification.
