Description

一种可用于RFID智能卡的激光全息印刷膜及其制造方法
【交叉引用】
本申请要求申请号为CN201620289819.9、申请日为2016年04月11日、实用新型名称为“一种可用于RFID智能卡的激光全息印刷膜”的中国专利申请的优先权，该申请的全部内容通过引用结合在本申请中。
【技术领域】
本申请实施例涉及智能卡制造领域，尤其涉及一种可用于RFID智能卡的激光全息印刷膜及其制造方法。
【背景技术】
目前制卡行业中使用比较广泛的激光全息印刷膜，通常都是镀铝层辅助达到全息彩虹和金属镜面效果。常用的激光全息印刷膜的纵向剖面结构分解示意图如图1所示，基膜PET膜14的上层为模压生成的全息层13，经过真空镀铝得到金属镜面铝层12，其上可以印刷图文信息，生成印刷层11。
在IC卡或智能卡制造领域，对接触式智能卡而言，使用镀铝的激光全息印刷膜是没有问题的，但是，对非接触式智能卡，例如RFID、NFC智能卡而言，由于铝层对射频电磁场的干扰和阻隔的作用，使得其射频频率及其他通讯指标都受到一定程度的干扰与衰减。据实验证实，在相同芯片及天线产品中，使用镀铝激光全息印刷膜的智能卡，其天线射频频率下降2MHz左右或更多，其相应通讯与支付的性能也会随之衰减，降低了功能，使得相应的射频无线功能不能正常工作，从而使得智能卡的读写功能无法正常进行，影响了智能卡的使用功能。
【发明内容】
本申请要解决的问题是：提供一种既具有金属镜面效果和全息彩虹效果的 印刷膜，又不会因金属镀层对智能卡的射频电磁场产生干扰和阻隔作用。常用的镀铝激光全息膜干扰和阻隔射频电磁场是因为镀铝层是金属导电层，如果此金属层电阻很大，不导电，则就不会产生对射频电磁场的干扰和阻隔作用，减少金属电镀层的厚度，其电阻会增大，当镀铝层的厚度等于0.9纳米时，镀铝层就变成不导电，但此时的镀铝层已变成透明层，不能产生金属镜面效果和全息彩虹效果。本申请解决了这一矛盾，经过反复实验找到了一种替代铝的金属铟和铟锡合金，当其电镀层的厚度在20-40纳米的范围内，其电阻很大而不导电，并且金属镜面效果和全息彩虹效果依然存在，可以作为RFID智能卡的激光全息印刷膜使用。
一方面，本申请所提出的一种可用于RFID智能卡的激光全息印刷膜，所述可用于RFID智能卡的激光全息印刷膜的基膜是PET材料层，其上模压全息图文信息层，并真空电镀金属铟层或铟锡合金层，其上可印刷图文信息。
如上所述的可用于RFID智能卡的激光全息印刷膜，其中，所述基膜是PET材料层的上表面是模压全息图文信息层。

如上所述的可用于RFID智能卡的激光全息印刷膜，其中，所述真空电镀金属铟层或铟锡合金层的上表面可印刷图文信息层。
另一方面，本申请所提出的一种可用于RFID智能卡的激光全息印刷膜的制造方法包括：
选择30μm厚度的PET塑料薄膜，并进行电晕工艺处理；
在模压机上进行模压激光全息图文信息；

如上所述的可用于RFID智能卡的激光全息印刷膜的制造方法，在通过真空电镀工艺，电镀金属铟锡合金的步骤中，电镀层的厚度为20-40纳米之间。
本申请的可用于RFID智能卡的激光全息印刷膜可以使具有RFID、NFC功能的智能卡产品在不做任何天线及芯片调整的情况下，用作此类卡体的印刷芯层，以达到设计所需的金属外观效果，并且对射频无线电磁场的干扰和影响比较低，不影响RFID智能卡的正常功能应用。
