配制混合标准溶液,利用顶空-气相色谱/质谱技术对食品纸包装材料中的8种有机溶剂进行残留量分析。结果表明:印刷油墨和润版液中含有较多有机溶剂;随着印刷墨量和印刷面积的增加,印品的溶剂残留量和苯类溶剂残留量都有所增加;印刷速度较快不利于印品的干燥;烘干温度对纸包装材料中的溶剂残留量也有一定的影响。 The mixed standard solutions were prepared and the residues of eight organic solvents in food paper packaging materials were analyzed by headspace-gas chromatography / mass spectrometry. The results show that: the printing ink and fountain solution contains more organic solvents; with the increase of printing ink and printing area, the residual solvent of printing ink and benzene residues have increased; the printing speed is not conducive to Printed products drying; drying temperature on the paper packaging materials in the solvent residues also have a certain impact.
