General performance and main advantages of PE stretch film

Unitization is one of the most prominent features of PE stretch film when used for packaging. Leveraging the film's exceptional wrapping strength and retractability, it tightly and securely bundles products into a single unit, keeping small, scattered items together. Even in adverse environments, the products remain intact and free of sharp edges and stickiness that could damage them.

Secondly, PE stretch film can provide primary protection for the packaged product. This primary protection provides surface protection for the product, creating a lightweight, protective coating to protect against dust, oil, moisture, water, and theft. More importantly, stretch film packaging evenly distributes stress on the packaged item, preventing damage from uneven distribution. This is something traditional packaging methods (such as strapping, packing, and tape) cannot achieve.

Third, it offers compression and fixation properties. PE stretch film has excellent tensile properties, and the resulting retraction force after stretching wraps the product, forming a compact, space-saving unit. This tightly wraps the products on each pallet, effectively preventing product displacement and movement during transport. Furthermore, the adjustable stretching force allows rigid products to adhere tightly and soft products to shrink, creating a unique packaging effect particularly effective in the tobacco and textile industries.

Fourth, using PE stretch film for product packaging can save costs. Under comparable conditions, using this type of stretch film for product packaging can significantly reduce costs: approximately 15% of conventional box packaging, 35% of heat shrink film, and approximately 50% of cardboard packaging. This also reduces labor intensity, improves packaging efficiency, and enhances packaging quality.

Compared to conventional protective film products, PE stretch film has a certain degree of self-adhesiveness. It can be considered a single-sided (cast) or double-sided (blown) plastic film that is stretchable and tightly wrapped around the item being wrapped. The self-adhesive adhesive does not adhere to the surface of the wrapped item, existing only on the film itself. Heat shrinkage is not required during the packaging process, saving energy, reducing packaging costs, facilitating containerized transportation, and improving logistics efficiency. The "full loading and unloading" method of combining pallets and forklifts reduces transportation costs, while its high transparency facilitates identification of packaged items and reduces delivery errors.

Based on the above analysis, PE stretch film is highly effective and practical, providing convenient packaging. It is not only non-toxic, environmentally friendly, moisture-proof, waterproof, dustproof, corrosion-resistant, puncture-resistant, and tear-resistant, but also boasts a long-lasting shrink memory, stable and reliable self-adhesive properties, and high transparency.
