Abstract
The purpose of the present invention is to propose a composition of slip additive agents for use in thermoplastic resins, preferably polyolefins, and consequently the presence of this composition on at least one of the layers of mono-extruded or coextruded, laminated or non-laminated films. More particularly, the invention comprehends a composition of additives which comprises at least one primary amide of the generic formula R—CO—NH2 and a secondary amide of the bis amide type of the generic formula R′—CO—NH—CH2—CH2—NH—CO—R″. Films comprising this composition stand out by achieving Coefficient of Friction (CoF) values lower than 0.35 and particularly by their ability to maintain good control over these values for use in the automated packaging industry.
