Adhesive sheeted roll

Abstract

There is herein described an improved adhesive sheeted roll. More particularly, there is described an improved adhesive sheeted roll and individual sheets making up the sheeted roll which contain no silicones.

1 . A sheeted roll for use in contact cleaning comprising:
 a roll core;   at least one sheet of adhesive material removably attached thereon;   wherein the adhesive sheet has two sides, a first side comprising adhesive and a second side comprising an embossed surface with the proviso that the adhesive sheet contains no silicones.   
     
     
         2 . A sheeted roll according to  claim 1 , wherein the sheeted roll comprises at least two or more or a plurality of sheets of adhesive material wound around each other and the roll core. 
     
     
         3 . A sheeted roll according to  claim 1 , wherein the sheets of adhesive material comprise an embossed surface facing inwardly on the individual adhesive sheets wherein the embossed surface contains no silicones. 
     
     
         4 . A sheeted roll according to  claim 1 , wherein the sheets of adhesive material are removably attached around the roll core. 
     
     
         5 . A sheeted roll according to  claim 1 , wherein the sheets of adhesive material are formed from a thermoplastic polymer in the form of a flexible film. 
     
     
         6 . A sheeted roll according to  claim 5 , wherein the thermoplastic polymer is a polypropylene with a molecular weight of about 150-270 kg mol −1 . 
     
     
         7 . A sheeted roll according to  claim 1 , wherein at least one or all of the sheets of adhesive material comprise an embossed surface to minimize the contact area of the adhesive on the sheets. 
     
     
         8 . A sheeted roll according to  claim 7 , wherein the embossing is in the form of a 3-dimensional regular or irregular pattern formed in the adhesive sheets. 
     
     
         9 . A sheeted roll according to  claim 7 , wherein the embossing reduces the contact area of the adhesive on the film by about less than 50%, 60%, 70%, 80% or 90%. 
     
     
         10 . A sheeted roll according to  claim 1 , wherein the adhesive sheets are biodegradable and recyclable and so the complete adhesive roll is environmentally friendly. 
     
     
         11 . A sheeted roll according to  claim 1 , wherein the sheets of adhesive material and/or adhesive and/or release coating comprise anti-static additives. 
     
     
         12 . A sheeted roll according to  claim 11 , wherein the anti-static additives are ionic salts used in a concentration of about 0.1-0.5 wt. %. 
     
     
         13 . A sheeted roll according to  claim 1 , wherein the sheets of adhesive material and/or adhesive and/or release coating comprise bacteriocides. 
     
     
         14 . A sheeted roll according to  claim 13 , wherein the bacteriocides are present in a concentration of about 0.1-0.5 wt. %. 
     
     
         15 . A method of removing debris and/or contaminants from a contaminated surface using a sheeted roll, said method comprising:
 providing a roll core;   providing at least one sheet of adhesive material removably attached to the core;   wherein the adhesive sheet has two sides, a first side comprising adhesive and a second side comprising an embossed surface with the proviso that the adhesive sheet contains no silicones.   
     
     
         16 . Apparatus for cleaning a workpiece, said apparatus comprising:
 at least one cleaning roll having a cleaning surface;   the cleaning roll being rotatably mountable adjacent to a workpiece;   the sheeted roll comprising at least one sheet of adhesive material removably attached thereon and being rotatably mounted adjacent the cleaning roll relative to the workpiece; and   wherein the at least one adhesive sheet has two sides, a first side comprising adhesive and a second side comprising an embossed surface with the proviso that the adhesive sheet contains no silicones.   
     
     
         17 . Apparatus according to  claim 16 , wherein the workpiece is used to form electronic components including that of plastic electronics, photovoltaics and flat panel displays.
