The resistance observed by the movement between two surfaces is termed as Friction. The Friction between polymer and polymer (i.e. between same molecules or different molecules ), this friction is called internal friction.
Friction between the polymer and the barrel wall: friction between the polymer and extruder screw surface, the forming die surface. These type of frictions are called external friction.
The function of the lubricant is to reduce the internal and external friction, to reduce the friction for ease the machine or material functioning.
Large friction means more energy loss, this increased processing cost
Uncontrolled energy usage, causing surface damage that creates quality control issues.
High friction makes damage to the polymer chains that, reduce the properties of the plastic

Working principle of slip additives

The low molecular material easily migrates to the outer surface of the product immediately after machining and form a favourable gliding layer on the surface, but high concentration may affect the printing on the product. The product uses slip additive that makes surface slides smoothly at time of contact. For the packaging industry, often uses waxes, such as ecuramide, ethylene Bis(streamside), Silicones in Polyethylene and Polypropylene resin.
