transparent when filled and coated on one face with the adhesive the resulting films are translucent so the user can see what lies below the applied tape not possible with present tapes moreover such transluscency eliminates gloss and also permits easy writing and printing on the tape whereas when one adds a filler to a film former the object is usually to minimize strength loss of the resulting film in the present invention the filler intentionally must substantially reduce the film strength since it usually will not be capable of transverse tearing by hand the precise amount of filler needed for this purpose will therefore depend upon the composition of the film its thickness other materials present such as plasticizer and the like for polyethylene films of about 0 05 to 0 15 mm in thickness about 25 to 60 and preferably about 40 to 50 by weight of filler based on polyethylene has proven adequate suitable fillers comprise inorganics such as calcium carbonate calcium sulphate magnesium salts kaolin sand and the like but organics such as sawdust starch cornmeal ground plastic waste and the like can also be used its particle size can vary widely about 0 5 to 10 and particularly about 1 to 4.
