Sec.  175.365  Vinylidene chloride copolymer coatings for polycarbonate 
film.

    Vinylidene chloride copolymer coatings identified in this section 
and applied on polycarbonate 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 polycarbonate resins complying with 
Sec.  177.1580 of this chapter.
    (b) The coatings are prepared from vinylidene chloride copolymers 
produced by copolymerizing vinylidene chloride with acrylonitrile, 
methyl acrylate, and acrylic acid. The finished copolymers contain at 
least 50 weight-percent of polymer units derived from vinyldene 
chloride.
    (c) Optional adjuvant substances employed in the production of the 
coatings or added thereto to impart desired properties may include 
sodium dodecylbenzenesulfonate in addition to substances described in 
Sec.  174.5(d) of this chapter.
    (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 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, shall yield net chloroform-soluble 
extractives in each extracting solvent not to exceed 0.5 milligram per 
square inch of coated surface as determined by the methods described in 
Sec.  176.170(d) of this chapter. In testing the finished food-contact 
articles, a separate test sample is to be used for each required 
extracting solvent.
    (e) Acrylonitrile copolymers identified in this section shall comply 
with the provisons of Sec.  180.22 of this chapter.
