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., Philadelphia, PA 19103, or may be examined at 
the Office of the Federal Register, 800 North Capitol Street, NW., suite 
700, Washington, DC 20408), 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.
