3. Definitions  
3.1 Reusable bags: bags made of plastic and have reusable properties that are 
different from single use or biodegradable bags.  
 
3.2 Bag length :  The vertical dimension between the open top and bottom of the bag, 
including any bottom gusset (a fold at the bottom intende d to increase the bag 
capacity).  
 
3.3 Bag width :  The lateral dimension between the two sides of the bag, including 
any side gussets (folds at the sides intended to increase the bag capacity).  
 
3.4 Bag thickness :  The thickness of a single layer polyethylene film used in making 
the bag.  
 
3.5 Blocking :  The adhesion between the touching sides of the bag.  
 
 
4.Requirments  
Reusable polyethylene plastic bags shall meet the following requirements:  
 
4.1 The material s used in manufacture of the bag shall be free from toxic materials or 
those expected to cause health hazards to users or those generally unsuitable for 
human use . They shall not be included as prohibited hazardous materials in the 
ministerial decree No. 25 /2009 for Regulation of Organization of Handling and Using 
of Chemicals issued by ministry of environment and climate affairs.  
 
4.2 The reusable plastic bags shall be complied with GSO standard mentioned in item 
(2.2).  
4.3 The reusable plastic bags shall be able to be used at least 125 times. They may be 
able to be recycled at the end of their using.  
  Omani Standard                                                                                                           ----/-----   OS   
 
 5 4.4 As for foodstuffs, the reusable plastic bag s shall not be used for packaging of 
fresh food . They shall not come into dir ect contact with the foodstuff, but rather 
prepacked foodstuffs or previously packaged with food grade materials . 
 
4.5 The thickness  of the reusable plastic bag shall not be less than 50 µm. 
 
4.6 Reusable plastic bag  should not be painted, tagged, packed , or otherwise 
treated to prevent recycling after consumption.  
 
4.7 The reusable plastic bag shall  be designed in a way that ensures ease of use in 
terms of bag handles, size and shape.  The base and handle of the bag can be made of 
non-plastic materials such as cardboard or other materials that are not harmful to the 
environment.  
 
4.8 If a mixture of p lastic waste is used to manufacture the reusable  bag, all products 
made from it that come into direct contact with soil and water s hall not have any 
negative impact on the environment.   
 
4.9 The reusable plastic bag shall be free from foreign materials and  from any bad 
manufacturing defects such as tears, pin holes, un -melted or carbonized gels or 
undesirable surface finish such as dye lines or other defects.  
 
4.10 The seal at the sides of the  reusable  plastic  bag shall be suitable, clean and free 
from any obvious defects.  The seal strength of the bag shall be not less than 75% of 
the ultimate strength of polyethylene film from which the bag is made, in two 
principal directions (vertical and horizontal).  
 
4.11 The reusable plastic bag seal shall be resistan t to leakage when tested with water.  
The mass of the test water used shall be equivalent to that of the shopping item 
intended to be placed in the bag, or when tested using compressed air.  
 
4.12 The reusable  plastic  bag shall open easily without any obvious blocking upon 
placing an object weighing 5 kg over them for 12 hours and under a temperature of 60  
ºC. 
 
4.13 The reusable  plastic  bag shall not be subjected to tear when packed with 
materials normally used for their p ackaging , according to the weight specified on the 
bag’s label,  and made to fall from a height of 1.2 m on a solid level surface.  
 
4.14 In case of any environment claims on reusable plastic bag, it shall be complied 
with item (2.1).  
 
4.15 The minimum tensile strength and elongation at break for heavy, medium and 
light duty reusable plastic bag materials, depending on their thickness shall be in 
accordance with table ( 1):
