Description
技术领域
本发明涉及热敏材料技术领域,具体涉及一种耐热水BOPP热敏膜及其制造方法。
背景技术
随着热敏材料在生活中各个领域的广泛使用,热敏膜的用途也在不断的拓展。
目前市场上有些熟食加工过程,有需要用高温热水进行消毒,使用的产品标签无法使用热敏纸类,一般使用BOPP基膜的热敏标签。有的餐厅则将饮品连杯子一起在热水中加热。高温水消毒或者加热过程对于BOPP膜热敏标签而言,要求在高温水中涂层牢固,并且热敏涂层不能明显变色影响条码和文字的识别。
由于热敏打印后无色染料和显色剂生成的显色物质在一定条件下会向逆反应转移,在热水条件下,几乎所有的直热式热敏打印图案都会不同程度产生逆反应,BOPP热敏膜产品也不例外。根据其涂层工艺的差异,在热水中产生的逆反应即所谓的褪色程度不同,并且在不同温度下的热水中涂层牢固程度以及条码文字消褪程度都不同。
目前市场上的BOPP热敏膜产品在耐热水方面的性能参之不齐,有的产品在高温热水中涂层严重掉层,有的条码文字严重褪色,有的随着水温的增加底色严重变灰变黑,无法正常使用。仅有少数国外产品做到涂层牢固和底色保持较好,但还是免不了会有褪色现象。
