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.  
 
MG or Machine Glazed  is an uncoated paper with shiny appearance on one side and a 
rough surface on the other side. It combines high tensile strength properties of Kraft paper 
together with smoothness and shine for excellent printability. MG is an ideal base paper for 
a vast range of packaging solutions and is also safe for direct food contact. MG paper 
shows low grammage variation across the profile of the paper and hence exhibits very 
good machinability.  
 
In the manufacturing sector , machine glazed Kraft paper is used for packa ging of dry food 
such as flour,  Sugar , cereals  etc. 
 
This standard shall be useful to manufacturers  of dry foods, converters,  importers , exporters, 
standards enforcement agencies and other stakeholders . 
 
Parameters covered in the standard include tensile strength,  tear strength,  burst index,  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:
