日前,欧盟食物链和动物健康常务委员会制定了含4-甲基二苯甲酮及二苯甲酮的印刷油墨食品包装的最大迁移限量,规定了食品包装印油墨材料内的4-甲基二苯甲酮及二苯甲酮总的迁移极限值必须低于0.6毫克/公斤。苯类物质一直以来被公认为是致癌物质,但苯类又是树脂材料的良好溶剂,它具有溶解能力强、挥发速度快、价格便宜等优点,因此被广泛用于树脂的溶剂,在包装中主要用于复合包装材料粘合剂和塑料印刷油墨的溶剂。
Recently, the EU Food Chain and Animal Health Standing Committee has developed a maximum migration limit of 4-methylbenzophenone and benzophenone printing ink food packaging, provides food packaging printing ink materials 4-methyldibenzene The total migration limit of ketones and benzophenones must be less than 0.6 mg / kg. Benzene has always been recognized as a carcinogen, but benzene is a good solvent for resin materials. It has the advantages of strong dissolving ability, fast volatilization, low price and so on. It is widely used as a solvent for resins in packaging Mainly used in composite packaging materials, adhesives and plastic printing ink solvent.
