Sometime a specific pre-treatment is required for some plastics such as polyolefins and certain technopolymers in order to make them printed, painted or glued.

The measurement of the surface tension takes place by measuring the contact angle of a fluid on the surface of the product, or, more quickly and easily, with the use of wetting measurement inks.
