Sec.  175.210  Acrylate ester copolymer coating.


    Acrylate ester copolymer coating may safely be used as a food-
contact surface of articles intended for packaging and holding food, 
including heating of prepared food, subject to the provisions of this 
section:
    (a) The acrylate ester copolymer is a fully polymerized copolymer of 
ethyl acrylate, methyl methacrylate, and methacrylic acid applied in 
emulsion form to molded virgin fiber and heat-cured to an insoluble 
resin.
    (b) Optional substances used in the preparation of the polymer and 
in the preparation and application of the emulsion may include 
substances named in this paragraph, in an amount not to exceed that 
required to accomplish the desired technical effect and subject to any 
limitation prescribed: Provided, however, That any substance named in 
this paragraph and covered by a specific regulation in subchapter B of 
this chapter must meet any specifications in such regulation.
