Hand stretch film is usually expected to be "thick and durable," but the new generation of ultra-thin products takes the opposite approach — at just 8 microns thick, roughly one-tenth the diameter of a human hair. How can a film this thin "punch above its weight"?

In automated warehouses, pallet stretch wrappers perform hundreds of wrapping cycles per shift. While the operation seems simple — just wrapping around a pallet — one roll of high-elongation stretch film can cover several times the area of conventional film. Behind this lies a frequently overlooked technical parameter: elongation rate.

Two rolls of clear stretch film may look identical, yet one can only handle simple bundling while the other secures an entire pallet load with confidence. The difference often lies not in thickness, but in structure.
