Cling adhesion of stretch wrap films, agricultural stretch films, catering films, cling films and other cling films

Surface adhesion describes the adhesion of two layers of film and is especially important in stretch wrapping, where several layers are placed on top of each other. In accordance with ASTM D 5458, the force required to separate two layers of film from each other is determined under reproducible conditions using standardised test equipment

In short — AI-generated

This test measures the cling adhesion of stretch wrap films by determining the force required to separate two layers of film from each other under reproducible conditions. The test is performed using standardized test equipment in accordance with ASTM D 5458. The goal is to evaluate the surface adhesion of the film, which is crucial in stretch wrapping where multiple layers are stacked on top of each other.

The resulting value indicates the strength of the cling adhesion, which is essential for ensuring that the film remains in place during transportation or storage. A higher value means stronger adhesion, while a lower value indicates weaker adhesion. This information is used by packaging developers and buyers to select the appropriate film for their specific needs and to ensure safe and secure packaging.
