摘要

PURPOSE: Provided is a barrier coating composition used to prepare a packing material for packing a common solid product (Kimbab, frozen lobster, potato chips, Sushi) without a PE film coating process. CONSTITUTION: The barrier coating composition comprises 39.9-45 % of a styrene-acrylate copolymer emulsion prepared by polymerizing 40-45 % of butyl acrylate, 40-45 % of styrene, 4-7 % of acrylonitrile, 4-7 % of methacrylic acid, 1-3 % of sodium dodecylbenzenesulfonate, 0.1-1 % of ammonium persulfonate and 0.9-2 % of ammonia water; 0.1-5 % of ammonia water; and 50-60 % of water.
