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. 177.1600 Polyethylene resins, carboxyl modified.
Carboxyl-modified polyethylene resins may be safely used as the
food-contact surface of articles intended for use in contact with food
in accordance with the following prescribed conditions:
(a) For the purpose of this section, carboxyl-modified polyethylene
resins consist of basic polymers produced when ethylene-methyl acrylate
basic copolymers, containing no more than 25 weight percent of polymer
units derived from methyl acrylate, are made
[[Page 306]]
to react in an aqueous medium with one or more of the following
substances:
Ammonium hydroxide.
Calcium carbonate.
Potassium hydroxide.
Sodium hydroxide.
(b) The finished food-contact article, when extracted with the
solvent or solvents characterizing the type of food and under the
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 total extractives in each extracting solvent not to
exceed 0.5 milligram per square inch of food-contact surface as
determined by the methods described in Sec. 176.170(d) of this chapter;
and if the finished food-contact article is itself the subject of a
regulation in parts 174, 175, 176, 177, 178, and Sec. 179.45 of this
chapter, it shall also comply with any specifications and limitations
prescribed for it by that regulation. In testing the finished food-
contact articles, a separate test sample is to be used for each required
extracting solvent.
(c) The provisions of paragraph (b) of this section are not
applicable to carboxyl-modified polyethylene resins used in food-
packaging adhesives complying with Sec. 175.105 of this chapter.
