Unitization
This is one of the most significant features of shrink film packaging. Leveraging the film's exceptional wrapping and retractability, products are tightly and securely bundled into a single unit, keeping small, scattered items together. Even in adverse environments, the product remains intact and free of sharp edges and stickiness to prevent damage.
Primary Protection
Primary protection provides surface protection for the product, creating a lightweight, protective coating around the product to protect against dust, oil, moisture, water, and theft. Crucially, 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.
Compression Fixation
The stretch film's retractive force allows products to be wrapped around the packaging, creating a compact, space-saving unit. This tightly wraps the products on each pallet, effectively preventing displacement and movement during transport. The adjustable stretching force allows rigid products to fit snugly and soft products to shrink, creating a unique packaging effect particularly effective in the tobacco and textile industries.
Cost Savings
Using stretch film for product packaging can significantly reduce operating costs. The cost of using stretch film is approximately 15% of that of conventional box packaging, 35% of heat shrink film, and 50% of cardboard packaging. It also reduces labor intensity, improves packaging efficiency, and enhances the quality of the packaging.
