ABSTRACT:
A bag fabricated of plastic film and particularly suited for holding pulverulent or granular food products, such as rice, is provided with a check valve which is also fabricated of plastic film. The check valve includes a filter surface located in the fluid flow path of the check valve. The check valve allows egress of air or other fluid from the bag and prevents ingress of air into the bag, while the filter serves to retain the bag contents within the bag.
