Pressure-sensitive adhesive label for hard disk drive

Abstract

A pressure-sensitive adhesive label has a base having an information indication portion on its one surface thereof, and a pressure-sensitive adhesive layer formed on another surface of the base. After peeling a release liner, the label is stuck on an outer surface of a housing of the hard disk drive to reduce noise generated when the hard disk drive is driven. The release liner for coating the pressure-sensitive adhesive layer has an antistatic function and a cut line. The adhesive force of the adhesive layer is reduced by heating. The label has a surface density of not lower than 0.18 (kg/m 2 )

1 . A pressure-sensitive adhesive label for a hard disk drive, to be adapted for being stuck on an outer surface of a housing of said hard disk drive so as to reduce noise generated when said hard disk drive is driven, said label comprising: 
 a base having an information indication portion on a first surface thereof;    a pressure-sensitive adhesive layer formed on a second surface of said base; and    a release liner for coating said pressure-sensitive adhesive layer and having an antistatic function.    
   
   
       2 . A pressure-sensitive adhesive label for a hard disk drive according to  claim 1 , wherein said release liner comprises a liner base and an antistatic-treated layer formed on said liner base.  
   
   
       3 . A pressure-sensitive adhesive label for a hard disk drive according to  claim 2 , wherein said release liner has one selected from a laminate structure of a laminate of said antistatic-treated layer and said liner base, and a laminate of said base, said antistatic-treated layer and said liner base.  
   
   
       4 . A pressure-sensitive adhesive label for a hard disk drive according to  claim 2 , wherein said antistatic-treated layer comprises one of a metal foil and a metal-vapor-deposited film.  
   
   
       5 . A pressure-sensitive adhesive label for a hard disk drive according to  claim 2 , wherein said release liner comprises a liner base and an antistatic agent dispersed in said liner base.  
   
   
       6 . A pressure-sensitive adhesive label for a hard disk drive according to  claim 1 , wherein said release liner partially comprises a polyolefin-based film.  
   
   
       7 . A pressure-sensitive adhesive label for a hard disk drive according to  claim 1 , wherein said release liner further comprises a release-treated layer.  
   
   
       8 . A pressure-sensitive adhesive label for a hard disk drive according to  claim 1 , wherein said release liner contains a silicone-free release agent as a release agent.  
   
   
       9 . A pressure-sensitive adhesive label for a hard disk drive according to  claim 1 , wherein said base comprises a metal foil and resin film layers laminated on opposite sides of said metal foil.  
   
   
       10 . A pressure-sensitive adhesive label for a hard disk drive according to  claim 9 , wherein said metal foil is not thinner than 5 μm.  
   
   
       11 . A pressure-sensitive adhesive label for a hard disk drive according to  claim 9 , wherein each of said resin film layers comprises a polyethylene terephthalate film.
