Subpart A [Reserved]



    (a) Adhesives may be safely used as components of articles intended 
for use in packaging, transporting, or holding food in accordance with 
the following prescribed conditions:
    (1) The adhesive is prepared from one or more of the optional 
substances named in paragraph (c) of this section, subject to any 
prescribed limitations.
    (2) The adhesive is either separated from the food by a functional 
barrier or used subject to the following additional limitations:
    (i) In dry foods. The quantity of adhesive that contacts packaged 
dry food shall not exceed the limits of good manufacturing practice.
    (ii) In fatty and aqueous foods. (a) The quantity of adhesive that 
contacts packaged fatty and aqueous foods shall not exceed the trace 
amount at seams and at the edge exposure between packaging laminates 
that may occur within the limits of good manufacturing practice.
    (b) Under normal conditions of use the packaging seams or laminates 
will remain firmly bonded without visible separation.
    (b) To assure safe usage of adhesives, the label of the finished 
adhesive container shall bear the statement ``food-packaging adhesive''.
    (c) Subject to any limitation prescribed in this section and in any 
other regulation promulgated under section 409 of the Act which 
prescribes safe conditions of use for substances that may be employed as 
constituents of adhesives, the optional substances used in the 
formulation of adhesives may include the following:
    (1) Substances generally recognized as safe for use in food or food 
packaging.
    (2) Substances permitted for use in adhesives by prior sanction or 
approval and employed under the specific conditions of use prescribed by 
such sanction or approval.
    (3) Flavoring substances permitted for use in food by regulations in 
this

part, provided that such flavoring substances are volatilized from the 
adhesives during the packaging fabrication process.
