CHAPTER I--FOOD AND DRUG ADMINISTRATION, DEPARTMENT OF HEALTH AND HUMAN
PART 177_INDIRECT FOOD ADDITIVES: POLYMERS--Table of Contents
Subpart B_Substances for Use as Basic Components of Single and Repeated
Use Food Contact Surfaces
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
(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.
