Foreword  
 
This Kenya Standard was prepared by the  Technical Committee on Packaging  (053)  under 
the guidance of the Standards Project s Committee, and it is in accordance with the 
procedures of the Kenya Bureau of Standards.  
 
Machine glazed  Kraft paper or board is one which has had one side made smooth and 
glossy by drying in contact with heated, polished  metal cylinder which  forms part of the 
drying section of the machine .  
 
 
In the manufacturing sector , machine glazed  Kraft paper is used for packaging of bread,  
grocery, cereals, confectionery , among others  
 
This standard shall be useful manufacturers  of dry foods, converters  importers , exporters, 
standards enforcement agencies and other stakeholders . 
 
Parameters covered in the standard include tensile, strength, moisture , pH, cobb, dimension  
Limits of heavy metals and organic contaminants , Microbiological  requirements among 
others . 
 
During the preparation of this standard, reference was made to the following document:
