Method for the manufacture of a smart label inlet web, and a smart label inlet web

Abstract

The invention relates to a method for the manufacture of a smart label inlet web, in which method a smart label is protected from external effects by means of a surface film coated with an adhesive, the adhesive being in contact with the smart label. The adhesive is cured by radiation. The invention also relates to a smart label inlet web comprising a surface film, a smart label and a back web attached to each other. The surface film is attached to the smart label with an adhesive cured by radiation.

1 . A method for the manufacture of a smart label inlet web, the method comprising protecting a smart label from external effects by means of a surface film coated with an adhesive, the adhesive being in contact with the smart label, wherein adhesive is cured by radiation.  
     
     
         2 . The method according to  claim 1 , wherein the adhesive is cured by means of ultraviolet (UV) radiation or electron beam (EB) curing.  
     
     
         3 . The method according to  claim 1  or  2 , wherein the adhesive is applied onto a surface web by transfer lamination.  
     
     
         4 . The method according to  claim 3 , wherein the surface web is a polyolefin film.  
     
     
         5 . The method according to  claim 4 , wherein the surface web is a polyolefin film.  
     
     
         6 . The method according to  claim 5 , wherein at least one of two contact surfaces forming the nip has a resilient surface.  
     
     
         7 . The method according to  claim 6 , wherein before attachment of the surface web, smart label web, and back web, release webs are released from a reverse side of the surface web and from a reverse side of the back web.  
     
     
         8 . The method according to  claim 5 , wherein after radiation of the adhesive, the smart label and the surface film on a surface of the back web are punched off the attached surface web and the smart label web, and excess material is removed.  
     
     
         9 . The method according to  claim 8 , wherein the ready smart label inlet web is reeled up on a roll.  
     
     
         10 . The method according to  claim 5 , wherein after radiation of the adhesive, the smart label, the surface film and the back film are punched off the attached surface web, smart label web and back web.  
     
     
         11 . A smart label inlet web comprising a surface film, a smart label and a back web attached to each other, wherein the surface film is attached to the smart label by an adhesive which is radiation curable.  
     
     
         12 . The smart label inlet web according to  claim 11 , wherein the surface film is attached to the smart label by means of an adhesive effective for being crosslinked by ultraviolet radiation or electron beam curing.  
     
     
         13 . A smart label card comprising a surface film, a smart label and a back film made of a back web, attached to each other, wherein the surface film is attached to the smart label by an adhesive which is radiation curable.  
     
     
         14 . The smart label card according to  claim 13 , wherein the surface film is attached to the smart label by means of an adhesive effective for being crosslinked by ultraviolet irradiation or electron beam curing.
