The stretched film refers to a polymer composite material as a main raw material, and is uniformly mixed with other auxiliary materials in a certain ratio, and then formed into a stretched film having a certain thickness (thickness of 0.01 to 0.25 mm), width and infinite length.
Stretched film can be seen everywhere in life, used as cover layer, canopy film and packaging of various agricultural products in agricultural production; packaging for various industrial products (mechanical parts, instruments, household appliances, etc.) in industrial production; Packing clothing and food in daily life, as well as rainproof equipment, toys and decorations.
Stretch film product characteristics:
Primary protection: The stretch film provides surface protection of the product, forming a light, protective appearance around the product to achieve dust, oil, moisture, water and security. It is especially important that the wrapping film package makes the packaged articles evenly stressed, and avoids damage caused by uneven force. This is the traditional packaging method (bundling, packing, tape, etc.).
Compression fixation: The product is wrapped and wrapped by the retractive force of the stretched film to form a compact, space-saving unit, so that the trays of the product are tightly wrapped together, which can effectively prevent the products during transportation. The mutual misalignment and movement, while the adjustable tensile force can make the hard product close to each other, making the soft product tight, especially in the tobacco industry and the textile industry.
Cost-saving: The product packaging can be effectively reduced by using the wrapping film. The winding film is only about 15% of the original box packaging, about 35% of the heat shrinkable film, and about 50% of the carton packaging. At the same time, it can reduce the labor intensity of workers, improve packaging efficiency and packaging grade.
