Lubricant

Additive that improves the sliding behaviour of thermo plastics, mostly films. Additives are: oleic acid amide = short-time effect, erucis acid amide = long-term effect. Function: basically, lubricants are incompatible with the polymer used and therefore migrate to the surface of the film where they form a glide able layer. An overdosis can be detrimental to the characteristics both in printing and welding the film.
