Abstract

The present invention is a container for storing fine particles such as bakery flour in a sealed packaging, wherein air in the container such as entrapped during filling can be expelled through compression without loss of the fine particles. The container comprises a main body forming a pouch, terminating in a principal opening, fabricated from an imperforate flexible material such as clear plastic film, a sealing mechanism attached to the pouch for sealing the pouch, and a multiplicity of microscopic pores extending through the flexible material having a dimension ranging from 10 to 150 .mu.m) sufficient to permit air to exit through the exit port, but to prevent the fine particles from escaping through the pores.
