Sec.  177.1615  Polyethylene, fluorinated.

    Fluorinated polyethylene, identified in paragraph (a) of this 
section, may be safely used as food-contact articles in accordance with 
the following prescribed conditions:
    (a) Fluorinated polyethylene food-contact articles are produced by 
modifying the surface of polyethylene articles through action of 
fluorine gas in combination with gaseous nitrogen as an inert diluent. 
Such modification affects only the surface of the polymer, leaving the 
interior unchanged. Fluorinated polyethylene articles are manufactured 
from basic resins containing not less than 85 weight-percent of polymer 
units derived from ethylene and identified in Sec.  177.1520 (a)(2) and 
(3)(i).
    (b) Fluorinated polyethylene articles conform to the specifications 
and use limitations of Sec.  177.1520(c), items 2.1 and 3.1.
    (c) The finished food-contact article, when extracted with the 
solvent or solvents characterizing the type of food

and under conditions of time and temperature characterizing the 
conditions of its intended use as determined from tables 1 and 2 of 
Sec.  176.170(c) of this chapter, yields fluoride ion not to exceed 5 
parts per million calculated on the basis of the volume of food held by 
the food-contact article.
