    The chromium (Cr III) complex of N-ethyl - N -heptadecylfluoro-
octane sulfonyl glycine containing up to 20 percent by weight of the 
chromium (Cr III) complex of heptadecylfluoro-octane sulfonic acid may 
be safely used as a component of paper for packaging dry food when used 
in accordance with the following prescribed conditions.
    (a) The food additive is used as a component of paper in an amount 
not to exceed 0.5 percent by weight of the paper.

    (2) The treated paper forms one or more plies of a paper in a 
multiwall bag and is separated from the food by at least one ply of

barrier between the food additive and the food. Such packaging films or 
grease-resistant papers conform with appropriate food additive 
regulations.

directions for its use to insure compliance with the requirements of
