Abstract: The method for producing a multilayer covering film includes having a pressure sensitive adhesive layer protected by a liner with a system for controlling adhesion. The method includes a step of forming the adhesion-controlling system, which includes an operation for selectively positioning a polymeric, non-adhesive material composition in microcavities provided on one face of the liner. The invention also relates to a multilayer film produced using this production method and a method for applying this multilayer film.

Abstract: The present invention relates to a method for the antimicrobial protection of a plane or non-plane surface of a material object, i.e. other than a human or animal body, characterized in that the face termed the inner face of a self-adhesive plastics film (1) coated on its face termed the inner face with a layer of adhesive (2) is applied against the surface of the object, said film being constituted by plasticized PVC comprising a polymeric plasticizer, said film being flexible and manually stretchable and capable of following the contour of a said surface, having an elongation at break of more than 50% and an ultimate tensile strength of less than 6000 N/m, and said film incorporating in its material or comprising on its surface termed the outer surface an antimicrobial agent rendering the outer surface of said film active against microbes.

Abstract: The invention relates to antimicrobial non-cross-linked polymers which are constituted of an ester and/or amide resin to which quaternary ammonium salts are bound by a covalent bond which is potentially reactive with water, the quaternary ammonium content being at least 1 M/kg, a well as to the use thereof for the preparation of a material having antimicrobial properties and to their methods of preparation.
