降低卷烟包装材料中甲醛含量的方法

Method of Decreasing the Content of Formaldehyde in Cigarette Packaging Materials

为了使卷烟包装材料中的甲醛含量能符合烟草行业要求,以高效液相色谱法作为检测手段,测试了卷烟包装材料印刷成品及其所使用的印刷用原纸和油墨等原辅材料中的甲醛含量变化情况,实验结果显示,通过对印刷用原辅材料进行质量控制,特别是更换甲醛含量高的原纸材料,可有效降低卷烟包装材料印刷成品中的甲醛残留量。

In order to make the content of formaldehyde in cigarette packaging materials meet the requirements of tobacco industry,used high performance liquid chromatography（HPLC） as a means of detection,the printing products of cigarette packaging materials were determined,including the printing paper,ink and other raw materials.The experimental results showed that the quality control of raw materials,especially the replacement of the printing paper which had high content of formaldehyde,was an effective way of decreasing the formaldehyde residues in cigarette packaging materials.
