jute yarns that are used to manufacture jute bags/sacks
are mainly processed in two different methods. One is
Normal Grade jute yarn processed with Mineral Oils
and the other one is Food Grade jute yarn processed with
Vegetable Oils (Hydrocarbon Free).
Grade jute bags are fit for packaging most of the agricultural
commodities like paddy, nuts, shelled lentils, soybeans, potatoes,
onions etc. and Food Grade jute bags are fit for packaging
rice, wheat, flour, coffee, cocoa beans etc. Since Food Grade
jute bags are manufactured from the yarn processed with Vegetable
Oils, these are also called VOT (Vegetable Oil Treated)
Hydrocarbon Free, VOT Jute Bags are now becoming most popular
for carrying food grains. Many countries are now using VOT
Jute Bags for packing coffee and cocoa beans exclusively to
maintain international standard of their products.
to IJO Standard 98/01, food grade jute bags should not contain
unsaponifiable matters exceeding 1250 mg/Kg. This could be
determined by methods described at 2.401 by International
Union of Pure and Applied Chemistry (IUPAC). This could be
also followed by British Standard BS 3845:1990 or European
Standard EN 766. New CAOBISCO method is also initialized recently.
duty jute sacks and light
weight hessian/burlap bags are made as Food Grade with
