ISBM Acetaldehyde Management:
\nKorean PET Bottle Guide<\/h1>\n

Acetaldehyde (AA) is the invisible quality failure in Korean PET water and beverage ISBM \u2014 a colourless aldehyde that migrates from PET resin into the product and produces a chemical off-taste that Korean water consumers detect at concentrations as low as 20 ppb. AA generation is a thermal degradation reaction that occurs in the injection barrel, and every Korean ISBM production decision from resin drying to barrel temperature to residence time directly determines whether the finished bottle delivers the flavour neutrality that Korean premium water and KFDA pharmaceutical standards require.<\/p>\n
