Indian retail packs are 200 g or 400 g in thin polythene under 100 gauge, with holes giving about 5 percent vent area, according to DMR. Humidity inside the pack of 87 to 90 percent gives the best colour. Unpacked paddy straw loses 40 to 50 percent of its weight in four days; packed, about 10 percent.
