Utilizing the film's superior wrapping force and retraction properties, products are tightly and securely bundled into a single unit, transforming scattered small items into a cohesive whole. Even in adverse environments, the products remain intact without any loosening or separation, and there are no sharp edges or adhesive residue to prevent damage. Primary protection: Primary protection provides surface protection for the product, forming a lightweight, protective outer layer around it, thus achieving dustproof, oilproof, moisture-proof, waterproof, and theft-proof purposes.
Most importantly, stretch film packaging ensures even stress distribution on the packaged items, preventing damage caused by uneven stress-something traditional packaging methods (bundling, packing, tape, etc.) cannot achieve. Compression and fixation: The stretch film's retraction force wraps the product, forming a compact, space-saving unit. This tightly wraps pallets together, effectively preventing misalignment and movement during transportation. Adjustable tension allows for tighter wrapping of rigid products and compression of flexible products, providing unique packaging effects, particularly beneficial in the tobacco and textile industries. Cost savings: Using stretch film for product packaging can effectively reduce costs. Stretch film costs only about 15% of traditional box packaging, about 35% of heat shrink film, and about 50% of cardboard box packaging. It also reduces labor intensity for workers, improves packaging efficiency, and enhances the overall packaging quality.
