Today main packing used in Ocean transportation export activity are 50 Kg /25 Kg poly-propylene woven bag.
Some of them are translucid in order to see the colour of the contained rice
Printing facilities and low tare of this Poly-propylene woven bag makes it the preferred rice packing system.
Paddy rice at the main South East Asia origin like India is still packed and transported in JUTE BAGS
(Jute was and is always the best packing for Paddy, Brown and also Milled Rice and can be re-used). High cost of a reusable packing like jute limits the jute bags use in export operations.
Most of Basmati Paddy is still packed and stored at the origin in Jute bags
The moisture inside the bags will not increase but the warehouse moisture must be under control and air must be without other smelling products to avoid the Rice in Jute bags to change their original taste and smell.
Basmati paddy is stored 1 year in jute bags in special warehouses where moisture and temperature are under control. Hermetic storage with reduction of oxygen level to a maximum 3 % in the sealed storage volume is used to eliminate the risk of mould generation in Paddy and Brown rice.
Mould generates mixotoxine and their fungus will produce Toxine very dangerous for human and animal consumption, forbidden in food chains.
