Adhesive tape

Abstract

The invention relates to an adhesive tape with a carrier composed of a film, there being applied on one side of the carrier an adhesive based on natural rubber or synthetic rubber, where the film is a biaxially oriented film made of polypropylene, polyethylene or polyester such as PET, and on the side of the carrier not coated with adhesive there is a release layer, based in particular on carbamate.

1 . Adhesive tape with a carrier composed of a film, there being applied on one side of the carrier an adhesive based on natural rubber or synthetic rubber, where
 the film is a biaxially oriented film made of polypropylene, polyethylene or polyester, and on the side of the carrier not coated with adhesive there is a release layer, based on carbamate.   
     
     
         2 . Adhesive tape according to  claim 1 ,
 wherein   the draw ratio on drawing of the film in longitudinal direction is 1:5 to 1:9, and/or   the draw ratio on drawing of the film in transverse direction is 1:5 to 1:10.   
     
     
         3 . Adhesive tape according to  claim 1 ,
 wherein   the draw ratio on drawing of the film in longitudinal direction (machine direction) is 1:3.5 to 1:6, and/or   the draw ratio on drawing of the film in the transverse direction is 3.5 to 1:6, and/or   the draw ratio on drawing of the film is the same in longitudinal and transverse directions.   
     
     
         4 . Adhesive tape according to  claim 1 ,
 wherein   the adhesive tape has fibre-like reinforcing materials, which are mounted directly on the film, incorporated into the film or incorporated into the adhesive.   
     
     
         5 . Adhesive tape according to  claim 1 ,
 wherein   the adhesive tape has a film carrier having a thickness of between 30 and 55 μm.   
     
     
         6 . Adhesive tape according to  claim 1 ,
 wherein   an adhesion promoter is applied between carrier and layer of adhesive.   
     
     
         7 . Adhesive tape according to  claim 1 ,
 wherein   the adhesive is selected from the group consisting of the natural rubbers or of the blends of natural rubbers and synthetic rubbers.   
     
     
         8 . Adhesive tape according to  claim 1 ,
 wherein   the adhesive comprises tackifier resins.   
     
     
         9 . Adhesive tape according to  claim 1 ,
 wherein   the adhesive comprises at least one UV protectant and/or other blending components.   
     
     
         10 . Method of using the adhesive tape according to  claim 1  for joining two webs (splicing). 
     
     
         11 . Method of using the adhesive tape according to  claim 1  as roll closure tape.
