PE stretch film (also known as wrap film) has high tensile strength, tear strength, and good self-adhesiveness, so that the object can be wrapped into a whole to prevent it from collapsing and falling during transportation. The film has excellent transparency, the packaged object is beautiful and generous, and can be waterproof, dustproof and damageproof.
1. Unitization: This is one of the biggest characteristics of wrapping film packaging. With the superior winding force and retracting property of the film, the product is compactly and fixedly bundled into one unit, so that the scattered small pieces become a whole, and the product does not loose or separate under the unfavorable environment, and there is no sharpness. Edge and stickiness to avoid damage.
2, primary protection: primary protection provides surface protection of the product, forming a very light, protective appearance around the product, thus achieving the purpose of dust, oil, moisture, waterproof, anti-theft. It is especially important that the wrapping film package makes the packaged articles evenly stressed, and avoids damage caused by uneven force. This is not the case with traditional packaging methods (bundling, packaging, tape, etc.).
3. Compression and fixation: The product is wrapped and wrapped by the retractive force of the stretched film
to form a compact unit that does not occupy space, so that the trays of the product are tightly wrapped together, which can effectively prevent the transportation process. The misalignment and movement of the products in the middle, while the adjustable tensile force can make the hard products close to each other, making the soft products tight, especially in the tobacco industry and the textile industry.
4. 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.
Stretch film (also known as wrap film) is mainly used in conjunction with pallets to complete the packaging of loose goods instead of small containers. Because it can reduce the cost of bulk cargo transportation and packaging by more than 30%, it is widely used in the complete packaging of various products in electronics, building materials, chemicals, metal products, auto parts, wire and cable, daily necessities, food, paper and other industries. In the field of warehouse storage, more and more stretch-wrapped film tray packaging is used for three-dimensional storage and transportation to save space and land occupation.
