收缩标签印刷油墨的特性与应用

文章出处: 人气:发表时间:2018-05-19 11:34

目前,广州印刷厂(miacarmina.com)在印刷生产中暂时认为可以用作热收缩材料印刷的油墨有4种:阳离子UV油墨、自由基UV油墨、溶剂型油墨及水性油墨。

  1.阳离子UV油墨

  即使在收缩率达到70%的条件下,这些新技术的自由基聚合型柔性版印刷油墨也能够体现出良好的耐摩擦性能,无须底涂和光油的配合使用。这类产品拥有高色强、固化速度快、优异的印刷适性及印品性能等优点。它可实现表印和里印两种工艺,同时其优异的固化性能和低黏度是产能的有效保证。

  由于水性凹版油墨还不能够全面替代甲苯类油墨,所以油墨行业一直在努力开发可以被环境接受的醇溶性油墨。醇溶性油墨能够有效解决甲苯类油墨对健康所产生的伤害和溶剂残留影响包装食品质量等问题。在欧洲和美国,这种发展已成为一种趋势。在亚洲,如新加坡、韩国等国家,甲苯类油墨正在被淘汰,将被醇溶凹版油墨所代替。醇溶性油墨现已在国内凹印行业得到了广泛应用,可以预见不久的将来,醇溶性油墨将占据中国收缩标签油墨市场的一定份额。

  4.水性油墨

  水性油墨一般使用在柔性版印刷中。水性油墨与溶剂型油墨的根本区别在与水性油墨使用的溶剂是水而不是有机溶剂,明显减少VOC排放量,能防止大气污染,不影响人体健康,不易燃烧,墨性稳定,色彩鲜艳,不腐蚀版材,操作简单,价格便宜,印后附着力好,抗水性强,干燥迅速,故特别适用与食品、饮料、药品等包装印刷品,是世界公认的环保型印刷材料,也是目前所有印刷油墨中唯一经美国食品药品协会认可的油墨。目前美国收缩薄膜产品印刷中有40%采用水性油墨,其他经济发达国家(如日本、德国、法国等)在薄膜印刷中使用水性油墨的用量也越来越多。据有关资料报道,在美国,符合VOC排放规定的水性墨必须达到使用状态的油墨组成中,挥发成分比例在25%以下,水分在75%以上;水分少的油墨在使用状态下,不挥发的成分在60%以上这两个标准。

  目前凹印中水性油墨也有了长足的进展。北京英科凡化工产品有限公司出产的WE型塑料薄膜凹版水性油墨以水为主要溶剂,以多种高分子聚合物为成膜物质,并配以高级有机颜料、无机颜料和多种助剂,符合环保要求,在表面张力达到(3.6~4.2)×10-2N/m的BOPP、PE、PET等塑料薄膜上有良好印刷性能和附着牢度。经彩印包装厂在BOPP膜上以70米/分钟的速度实际印刷后表明,其印刷效果和性能可以达到以芳香烃为主要溶剂的同类产品水平。
