Abstract
A process of packaging a solid gas evolving product by filling a plurality of pouches with the product, partially sealing each pouch mouth by a heat seal to leave a relatively small tortuous passage for the escape of gas from the product, transferring the pouches to a storage chamber containing oxygen at atmospheric conditions of temperature and pressure, storing the filled pouches in the chamber until substantially all of the gas capable of evolving from the product has evacuated the pouches, removing the pouches from the storage chamber and thereafter hermetically sealing the pouches against oxygen containing atmosphere by completely sealing each tortuous passage.
