FACTORS INFLUENCING METHANOL RELEASE DURING WHITE CARDBOARD TESTING
Because of most of volatile organic compounds(VOCs)are toxic,their content in the products,especially for the human contact materials,have been regulated in many countries.As a member of VOCs,methanol in white cardboard has been strictly restricted(< 3 mg·m-2)by the tobacco industry in China.This study provided an understanding of the factors on methanol release behaviors during the pulp or white cardboard testing by headspace gas chromatographic(HS-GC)technique.The results showed that the types of pulp(lignin content),water content and oxygen involved in the test have a significant effect on the methanol release from samples during the testing.The larger volume of glycerol triacetate can reduce the detection sensitivity for the VOCs analysis in the current HS-GC method.Therefore,it is important to address these points in order to have a unified standard procedure on the methanol testing of white cardboard papers.
