Stretch film, also known as wrapping film, elastic film, or wrapping film, is a self-adhesive plastic film that can be stretched and tightly wrapped on one side (cast film) or both sides (blown film). The adhesive does not adhere to the wrapped item, remaining only on the film itself. It eliminates the need for heat shrinking during the packaging process, saving energy, reducing packaging costs, facilitating containerized transportation, and improving logistics efficiency. The "full loading and unloading" method of pallets and forklifts reduces transportation costs, while its high transparency facilitates identification of packaged items and reduces delivery errors.
Product Advantages:
1. Excellent stretchability and high elongation
2. Strong puncture and tear resistance;
3. Long-lasting shrinkage memory;
4. Stable and reliable self-adhesion;
5. High transparency;
6. Non-toxic, environmentally friendly, moisture-proof, waterproof, dust-proof, and corrosion-resistant.
Stretch Film Characteristics:
1. Primary Protection: Primary protection provides surface protection for products, creating a lightweight, protective coating around them to protect against dust, oil, moisture, water, and theft. Crucially, stretch film packaging evenly distributes stress on the packaged items, preventing damage caused by uneven distribution. This is unattainable with traditional packaging methods (such as strapping, packing, and tape).
2. Compression and Fixation: Stretch film utilizes the retractive force of the film after stretching to wrap the product, forming a compact, space-saving unit. This tightly wraps the products on each pallet, effectively preventing displacement and movement during transportation. The adjustable stretching force allows rigid products to adhere tightly and flexible products to shrink, creating a unique packaging effect particularly useful in the tobacco and textile industries.
3. Cost Savings: Using stretch film for product packaging can significantly reduce operating costs, with the cost of using stretch film being approximately 15% of that of conventional box packaging, 35% of that of heat shrink film, and 50% of that of cardboard packaging. At the same time, it can reduce the labor intensity of workers and improve packaging efficiency and packaging grade.
