中文摘要:
      目的 研究UV油墨光引发剂在食品包装材料中的残留行为。方法 以2种常用的UV油墨光引发剂EDB和907为研究对象,分别以PET薄膜和铜版纸为承印材料,通过IGT印刷适性仪控制印刷膜层厚度,IGT UV干燥器控制紫外光固化时间,研究光照能量、墨层厚度和油墨浓度对光引发剂在食品包装材料中残留的影响。结果 光引发剂残留量会随着光照能量的增加而减少,随着墨层厚度增加而增加。对于PET薄膜,油墨含量高时光引发剂的残留量比油墨含量低时大,而铜版纸结果相反,油墨含量高时光引发剂的残留量较小。结论 在实际UV油墨印刷中,应提高光照能量,对于不同的承印材料应采用含量不同的油墨,以减少光引发剂的残留,降低其迁移风险,增加食品包装的安全性。
英文摘要:
      It aims to study the residual behavior of UV ink photoinitiators in food packaging materials. With the two commonly used photoinitiators EDB and 907 as objects of study and PET film and art paper as substrates, thickness of printing film was controlled by IGT printability tester and polymerization time of ultraviolet light was controlled by IGT UV dryer. The effect of light energy, ink thickness and ink density on residual photoinitiators in food packaging materials was investigated. The results showed that the amount of residual photoinitiators decreased as light energy increased but grew as ink thickness became bigger. For PET film, residues in high-density ink were higher than those in low-density ink. Conversely, for art paper, residues were less in high-density ink. In conclusion, light energy should be increased in practical UV ink printing. Inks of different densities should be applied to different substrates so as to reduce residual photoinitiators, lower the risk of transition, and improve the safety of food packaging.
