Abstract

A tipping wrapper for aerosol generating articles has a base layer with a porosity of less than 1.5 C.U., wherein the base layer contains at least one filler material, the tipping wrapper further including a surface which is pigmented with a pigment component which contains CaCO3 and at least a second component serving as a non-combustible filler, the pigment component having a grammage of at least 2.0 gsm, wherein the pigmented surface has a surface smoothness of at least 400 sec. A method for producing a tipping wrapper for cigarettes includes providing a base layer of the tipping wrapper, and coating the base layer with a solution containing a filler component, wherein the coated base layer is pressed and heated at a predefined temperature which is greater than 100° C.

Claims

exact text as granted — not AI-modified
1 . A tipping wrapper for aerosol generating articles having a base layer with a porosity of less than 1.5 C.U., wherein the base layer contains at least one filler material, the tipping wrapper further comprising a surface which is pigmented with a pigment component which contains CaCO 3  and at least a second component serving as a non-combustible filler, the pigment component having a grammage of at least 2.0 gsm, wherein the pigmented surface has a surface smoothness of at least 400 sec. 
     
     
         2 . The tipping wrapper according to  claim 1 , wherein:
 the base layer and the pigmented surface form a double layer structure.   
     
     
         3 . The tipping wrapper according to  claim 1 , wherein:
 the at least one filler material of the base layer is at least one of Kaolin, CaCO 3 , talc or Al(OH) 3 .   
     
     
         4 . The tipping wrapper according to  claim 1 , wherein:
 a basis weight of the tipping wrapper is greater than 40 gsm and smaller than 60 gsm.   
     
     
         5 . The tipping wrapper according to  claim 1 , wherein:
 a thickness of the tipping wrapper is greater than 30 microns and smaller than 55 microns.   
     
     
         6 . The tipping wrapper according to  claim 1 , wherein:
 a paper density of the tipping wrapper is greater than 1.1 g/cm 3  and smaller than 1.3 g/cm 3 .   
     
     
         7 . The tipping wrapper according to  claim 1 , wherein:
 a smoothness of the tipping wrapper is greater than 500 sec.   
     
     
         8 . The tipping wrapper according to  claim 1 , wherein:
 a smoothness of the tipping wrapper is smaller than 2500 sec.   
     
     
         9 . The tipping wrapper according to  claim 1 , wherein:
 a glossiness of the tipping wrapper is greater than 10%.   
     
     
         10 . The tipping wrapper according to  claim 9 , wherein:
 the glossiness of the tipping wrapper is smaller than 35%.   
     
     
         11 . The tipping wrapper according to  claim 1 , wherein:
 the pigment component contains CaCO 3  and Kaolin in a ratio which is between 3:7 and 7:3.   
     
     
         12 . The tipping wrapper according to  claim 1 , wherein:
 an amount of the pigment component is higher than 5 gsm.   
     
     
         13 . The tipping wrapper according to  claim 1 , wherein:
 the tipping wrapper is free of titanium dioxide (TiO 2 ).   
     
     
         14 . The tipping wrapper according to  claim 1 , wherein:
 the pigmented surface is based on a coating solution which comprises water, a binder component and the pigmentation component.   
     
     
         15 . A cigarette comprising the tipping wrapper according to  claim 1 . 
     
     
         16 . A method for producing a tipping wrapper for cigarettes comprising the steps:
 providing a base layer of the tipping wrapper,   coating the base layer with a solution containing a pigment component which contains CaCO 3  and at least a second component serving as a non-combustible filler, and   pressing and heating the coated base layer to form a pigmented surface having a surface smoothness of at least 400 sec.   
     
     
         17 . The method according to  claim 16 , wherein:
 the coated base layer is pressed and heated at a predefined temperature which is greater than 100° C. and below 300° C.
