Characteristics, development and use of stretch film

Currently, PE stretch film is widely used in the sales and transportation of various products, primarily to stabilize, cover, and protect them. PE stretch film must possess high puncture resistance, good shrinkage, and a certain degree of shrinkage stress. Furthermore, the film must be free of holes during the shrinkage process. Since shrink film is often used outdoors, it requires the addition of a UV stabilizer.

During the production process, PE stretch film is made by adding a certain amount of additives to a base material. It is currently widely used in product packaging. Stretch film is primarily made of plastic, and to meet current environmental standards, its use is constantly evolving. Currently, materials have expanded to primarily LLDPE, including C4, C6, C8, and metallocene PE. From single-layer to two- and three-layer, it is more durable. Depending on the application requirements, it can be packaged in both automatic and manual packaging.

First, let's take a look at the key features of PE stretch film:

1. It offers excellent flexibility, is not easily breakable, and offers strong resistance to blasting, impact, and tearing, as well as high tensile strength, making it a viable alternative to box packaging.

2. This product shrinks significantly, allowing it to tightly wrap items. If made into a PE straight-through bag (open at both ends), after heat shrinking, the open ends can be used to lift items, capable of supporting up to 15 kg, making it easy to carry.

3. Its excellent transparency, with a light transmittance of up to 80%, allows for product display and intangible promotion, while also reducing delivery errors during logistics and improving work efficiency.

4. This product is also moisture-proof, waterproof, and dust-proof, ensuring both packaging effectiveness and aesthetics and protection.

5. This product is safe and environmentally friendly, being non-toxic, odorless, and pollution-free, making it an environmentally friendly packaging material.

The application range of PE stretch film products is continuously expanding. Commonly used industries include pharmaceuticals, beverages, mineral water, beer, laminate flooring, palletizing, building materials, metal products, dairy products, glass bottles, industrial paper, and other large equipment and items requiring packaging.

In fact, PE stretch film products can not only be used to protect these products, but also meet the functions of moisture and dustproof, anti-tampering, transparent display, etc., which can increase the product's appearance and appeal. It can also be used to replace various paper boxes, not only saving packaging costs but also conforming to packaging trends. In addition, PE stretch film can be processed into various shaped bags according to different usage requirements: flat bags, arc bags, trapezoidal bags, three-dimensional bags, etc.
