"Packed without oxygen (as in our Super Pails (SP) which have the foods packed in thick Mylar Bags, 4mil thick, with oxygen absorbers added. The lined, absorbed foods are placed in a food grade plastic, FDA approved 6 gallon bucket with a Gasket Lid, hammered in place forming a secondary airtight seal). All Buckets RB and SP have a handle for lifting the buckets. Regular Buckets (RB) are foods packed in a food grade 6 gallon bucket with oxygen absorbers added and a gasket lid forming an airtight seal is hammered into place, #10 cans, #2.5 cans, Mylar Bags, with an airtight seal, Cooler 70 degrees F. or , dry and dark – out of direct sunlight. (
RB is not recommended for long-term storage, because of possible loss of bucket integrity due to pliability of buckets, denting and cracking; thus exposing the foods to oxygen prematurely. If the bucket integrity holds, then the foods would be preserved for a longer period of time.) We recommend RB storage, if you are looking for a 3-5 year shelf life, but do not guarantee the integrity of the buckets longer than a few years....." -
