Abrasion test of printings acc. Dr. Ruf method

Determination of abrasion resistance of printings, laqcuers etc. The test can be performed dry (as received), wet (after immersion in water) or after storage in liquid media/filling goods respectively after other pretreatments (sterilization, UV irradiation).

In short — AI-generated

The Dr. Ruf method tests the abrasion resistance of printings and lacquers on flexible packaging by rubbing a standardized friction element over the surface under defined pressure. The test can be performed on dry samples, samples wetted with water, or samples previously exposed to specific filling goods, sterilization, or UV radiation.

The result indicates how well the print adheres to the substrate and resists mechanical wear during transport and handling. This value helps packaging developers ensure that the print quality remains intact throughout the product's shelf life and under specific environmental conditions.
