PART 177_INDIRECT FOOD ADDITIVES: POLYMERS--Table of Contents

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, 1916 Race St.,

Records Administration (NARA). For information on the availability of

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.
