Sec.  175.360  Vinylidene chloride copolymer coatings for nylon film.

    Vinylidene chloride copolymer coatings identified in this section 
and applied on nylon film may be safely used as food-contact surfaces, 
in accordance with the following prescribed conditions:
    (a) The coating is applied as a continuous film over one or both 
sides of a base film produced from nylon resins complying with Sec.  
177.1500 of this chapter.
    (b) The coatings are prepared from vinylidene chloride copolymers 
produced by copolymerizing vinylidene chloride with one or more of the 
monomers acrylic acid, acrylonitrile, ethyl acrylate, methacrylic acid, 
methyl acrylate, methyl methacrylate (CAS Reg. No. 80-62-6; maximum use 
level 6 weight percent) and 2-sulfoethyl methacrylate (CAS Reg. No. 
10595-80-9; maximum use level 1 weight percent). The finished copolymers 
contain at least 50 weight percent of polymer units derived from 
vinylidene chloride. The finished coating produced from vinylidene 
chloride copolymers produced by copolymerizing vinylidene chloride with 
methyl methacrylate and/or 2-sulfoethyl methacrylate, or with methyl 
methacrylate and/or 2-sulfoethyl methacrylate together with one or more 
of the other monomers from this section, is restricted to use at or 
below room temperature.
    (c) Optional adjuvant substances employed in the production of the 
coatings or added thereto to impart desired properties may include 
sodium dodecylbenzenesulfonate.

    (d) The coating in the finished form in which it is to contact food, 
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, shall yield net chloroform-soluble 
extractives not to exceed 0.5 milligram per square inch of coated 
surface when tested by the methods described in Sec.  176.170(d) of this 
chapter.
    (e) Acrylonitrile copolymers identified in this section shall comply 
with the provisions of Sec.  180.22 of this chapter.
