Explanation of tensile film properties

Tensile film is also called stretch film and heat shrink film. It was originally produced with PVC as the base material and DOA as the plasticizer to play a self-adhesive role. Due to environmental protection issues, high cost (relatively large proportion of PE, less unit packaging area), poor stretchability and other reasons, when China began to produce PE stretch film in 1994-1995, it was gradually eliminated. PE stretch film first uses EVA as the self-adhesive material, but its cost is high, and it has a taste, and then develops to use PIB, VLDPE as the self-adhesive material, and the base material is mainly LLDPE, including C4, C6, C8 and metallocene PE ( MPE).

Stretch film series: manual stretch film, machine stretch film. Product introduction: Stretch film is also called elastic film, self-adhesive film, packaging stretch film, boxing film, and packing film. When in use, the film itself can be stretched and wrapped with self-viscous elasticity, and the product can only be wrapped by the viscoelasticity of the film surface and the stretching tension during use to achieve the purpose of protecting the product.

It adopts imported linear polyethylene LLDPE resin and special tackifier proportion formula for production, can produce hand-use, profit-seeking machine use, pre-stretching machine stretch film, anti-ultraviolet, Kangjining store and anti-rust and other multi-functions Stretch film. Has the following advantages:

1. Using double-layer co-extrusion equipment, the compressed stretch film can maximize the characteristics of each polymer, its transparency, tensile strength, anti-perforation strength, and the optimal state when it reaches the melting point.

2. It has the characteristics of good stretching performance, good transparency and uniform thickness.

3. It has the advantages of longitudinal extensibility, good resilience, good transverse tear resistance, and self-adhesive lap performance.

4. It is an environmentally friendly recyclable material, non-toxic and tasteless, and can directly package food. It is a food-grade packaging material.

5. It can manufacture single-sided viscous products, reduce the noise generated during winding and stretching, and reduce dust and gravel during transportation and storage.

Stretch film has the characteristics of high tensile strength, high elongation, strong flexibility, high transparency, etc., which can be widely used in centralized packaging of various goods. The stretch film is sticky on one side and can be stretched and wrapped tightly. Packing items so that they are not scattered, damaged, or polluted during storage and transportation. At the same time, due to high transparency, they can be easily identified and reduce mis-distribution. And it is also convenient for container storage and transportation, especially suitable for pallet packaging. It can realize mechanized loading and unloading operations, greatly improving the packaging and transportation speed. This product is mainly suitable for cargo pallet packaging, such as electronics, building materials, chemicals, metal products, and automobiles. Bundling and packaging of accessories, wires and cables, daily necessities, food and other industries.
