GrainPro SuperGrainbags™
The ultimate solution for quality preservation of agricultural commodities in bags

GrainPro has developed unique solutions for storage of agricultural commodities in airtight bags. Most agricultural commodities stored in these bags will develop a "modified atmosphere" of low oxygen and high carbon dioxide content. This "hermetic storage" is created by respiration of living organisms in the commodity such as insects and fungi.

Commodities can be stored for prolonged periods without the use of chemicals and refrigeration and without the risk of moisture ingress. The result is that aroma, color, freshness and germination are preserved, rancidity is prevented and insect infestation and fungi are controlled.
