TITLE 21--FOOD AND DRUGS
CHAPTER I--FOOD AND DRUG ADMINISTRATION, DEPARTMENT OF HEALTH AND HUMAN
SERVICES (CONTINUED)
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. 177.1610 Polyethylene, chlorinated.
Chlorinated polyethylene identified in this section may be safely
used as articles or components of articles that contact food, except for
articles used for packing or holding food during cooking, subject to the
provisions of this section.
(a) For the purpose of this section, chlorinated polyethylene
consists of basic polymers produced by the direct chlorination of
polyethylene conforming to the density, maximum n-hexane extractable
fraction, and maximum xylene soluble fraction specifications prescribed
under item 2.1 of the table in Sec. 177.1520(c). Such chlorinated
polyethylene contains a maximum of 60 percent by weight of total
chlorine, as determined by ASTM 1method D1303-55 (Reapproved 1979),
``Standard Test Method for Total Chlorine in Vinyl Chloride Polymers and
Copolymers,'' which is incorporated by reference (Copies may be obtained
from the American Society for Testing Materials, 100 Barr Harbor Dr.,
West Conshohocken, Philadelphia, PA 19428-2959, or may be examined at
the National Archives and Records Administration (NARA). For information

regulations/ibr--locations.html.), and has a 7.0 percent maximum
extractable fraction in n-hexane at 50 [deg]C, as determined by the
method described in Sec. 177.1520(d)(3)(ii).
(b) Chlorinated polyethylene may be used in contact with all types
of food, except that when used in contact with fatty food of Types III,
IV-A, V, VII-A, and IX described in table 1 of Sec. 176.170(c) of this
chapter, chlorinated polyethylene is limited to use only as a modifier
admixed at levels not exceeding 15 weight percent in plastic articles
prepared from polyvinyl chloride and/or from vinyl chloride copolymers
complying with Sec. 177.1980.
