Sec.  175.125  Pressure-sensitive adhesives.

    Pressure-sensitive adhesives may be safely used as the food-contact 
surface of labels and/or tapes applied to food, in accordance with the 
following prescribed conditions:
    (a) Pressure-sensitive adhesives prepared from one or a mixture of 
two or more of the substances listed in this paragraph may be used as 
the food-contact surface of labels and/or tapes applied to poultry, dry 
food, and processed, frozen, dried, or partially dehydrated fruits or 
vegetables.
    (1) Substances generally recognized as safe in food.
    (2) Substances used in accordance with a prior sanction or approval.
    (3) Color additives listed for use in or on food in parts 73 and 74 
of this chapter.
    (4) Substances identified in Sec.  172.615 of this chapter other 
than substances used in accordance with paragraph (a)(2) of this 
section.
    (5) Polyethylene, oxidized; complying with the identity prescribed 
in Sec.  177.1620(a) of this chapter.
    (6) 4-[[4, 6-Bis(octylthio)-s-triazin-2-yl]amino]-2,6-di-tert-
butylphenol (CAS Reg. No. 991-84-4) as an antioxidant/stabilizer at a 
level not to exceed 1.5 percent by weight of the finished pressure-
sensitive adhesive.
    (7) 2,2'-(2,5-Thiophenediyl)-bis(5-tert-butylbenzoxazole) (CAS Reg. 
No. 7128-64-5) as an optical brightener at a level not to exceed 0.05 
percent by weight of the finished pressure-sensitive adhesive.
    (8) 2-Hydroxy-1-[4-(2-hydroxyethoxy) phenyl]-2-methyl-1-propanone 
(CAS Reg. No. 106797-53-9) as a photoinitiator at a level not to exceed 
5 percent by weight of the pressure-sensitive adhesive.
    (9) Butanedioic acid, sulfo-1,4-di-(C9-C11 
alkyl) ester, ammonium salt (also known as butanedioic acid sulfo-1, 4-
diisodecyl ester, ammonium salt [CAS Reg. No. 144093-88-9]) as a surface 
active agent at a level not to exceed 3.0 percent by weight of the 
finished pressure-sensitive adhesive.
    (b) Pressure-sensitive adhesives prepared from one or a mixture of 
two or more of the substances listed in this

paragraph may be used as the food-contact surface of labels and/or tapes 
applied to raw fruit and raw vegetables.
    (1) Substances listed in paragraphs (a)(1), (a)(2), (a)(3), (a)(5), 
(a)(6), (a)(7), (a)(8), and (a)(9) of this section, and those substances
