Cooling roller helps packaging materials maintain their mechanical properties and appearance characteristics by rapid and uniform cooling. For example, plastic film can avoid warping or shrinkage caused by thermal stress under the action of cooling roller, thereby ensuring the thickness uniformity and flatness of the film.

Compared with traditional rollers, the surface flatness and finish of mirror rollers have been greatly improved. This smooth surface not only reduces the friction coefficient, but also greatly reduces the occurrence of surface damage during operation.

Stainless steel itself has higher tensile strength and toughness, but compared with chrome plated roller, the hardness of stainless steel roller may be slightly inferior. Therefore, stainless steel rollers may suffer certain wear and tear when operating for a long time or facing high-intensity pressure.
