Description

一种防伪膜、防伪膜的制作工艺及覆膜工艺 技术领域
本发明涉及印铁包装领域，特别是涉及一种防伪膜、防伪膜的制作工艺及覆膜工艺。
背景技术
在目前的包装领域，通常会采用到防伪膜，如在罐体或桶体的铁料表面贴附一张防伪膜。防伪膜为单层膜，在膜的表面进行单色或彩色防伪图案的印刷，然后在膜的背面涂胶后贴附在铁料的表面。虽然单层膜的印刷及贴附工艺均十分简单，但是防伪图案色彩变化单一，很难起到防伪的效果；并且胶水作为粘合材料，低温贴合在铁料表面，附着力并不是很好，容易脱落，达不到防伪的目的。
发明内容
本发明的一个目的是提供一种防伪膜。
为达到上述目的，本发明采用的技术方案是：
一种防伪膜，该防伪膜被贴附在罐体或桶体上，包括基层膜、位于所述的基层膜上具有防伪图案的印刷层、位于所述的基层膜上和/或所述的印刷层上具有镭射效果图案的镭射层以及镀铝层，所述的镀铝层位于所述的镭射层上。
优选地，所述的镀铝层还位于部分或全部所述的印刷层上。
优选地，所述的镭射层为镭射印压层或者为转移膜层。
本发明的另一个目的是提供一种防伪膜的制作工艺。
为达到上述目的，本发明采用的技术方案是：
一种防伪膜的制作工艺，包括：选择基层膜；在所述的基层膜上印刷防伪图案并形成印刷层；在所述的基层膜或印刷层上镭射压印或转移具有镭射效果的图案并形成镭射层；
在所述的印刷层和镭射层上选择需要呈现金属光泽的区域，在其余区域涂覆水洗油墨形成水洗油墨层；在需要呈现金属光泽的区域和所述的水洗油墨层上进行镀铝，形成镀铝层；对所述的水洗油墨层进行水洗，洗除所述的水洗油墨层以及镀在所述的水洗油墨层上的镀铝层，直接镀在需要呈现金属光泽的区域的镀铝层留在所述的印刷层和镭射层上。
优选地，所述的镭射层为需要呈现金属光泽的区域。
优选地，所述的基层膜选择PET膜或PP膜或OPP膜或PE膜。
本发明的另一个目的是提供一种覆膜工艺。
为达到上述目的，本发明采用的技术方案是：
一种覆膜工艺，包括制作所述的防伪膜；在所述的防伪膜的基层膜背面涂覆胶体，并将其贴附在铁料表面，使所述的防伪膜贴牢在所述的铁料上。
优选地，将所需覆膜的铁料加热至50~100度之间与所述的防伪膜进行贴合，贴合后在放入50-100度之间的烘房进行72小时的熟化，使所述的防伪膜贴牢在所述的铁料上。
优选地，将所需覆膜的铁料加热至200~350度立即与所述的防伪膜进行贴合，贴合后立即通过常温水辊进行冷却固化。
由于上述技术方案运用，本发明与现有技术相比具有下列优点和效果：
本发明在基层膜上印制好团花效果，然后再将镭射效果定位融入，形成多层共体膜，再通过贴合工艺与铁皮复合形成最终的防伪覆膜铁，防伪种类多样化，图案生动、色彩炫动，具有较强的防伪效果。
附图说明
附图1本发明中防伪膜的剖视示意图。
其中：1、基层膜；2、印刷层；3、镭射层；4、镀铝层。
具体实施方式
下面结合附图及实施案例对本发明作进一步描述：
如图1所示的一种防伪膜，其包括基层膜1、位于基层膜1上具有防伪图案的印刷层2、具有镭射效果图案的镭射层3以及镀铝层4。镭射层3为通过镭射压印防伪图案的镭射印压层或者为通过转移膜贴附防伪图案的转移膜层。镭射层3可以设定位于在基层膜1或印刷层2上的特定区域实现特定的镭射展现力，加大防伪效果；镀铝层4主要位于镭射层3上，印刷层2上也可以设置镀铝层4呈现光泽效果或者透明可视的特殊效果。
以下具体阐述下本实施例中防伪膜的制作工艺：
具体包括：选择基层膜，基层膜可以选择PET膜或PP膜或OPP膜或PE膜等；在基层膜上印刷防伪图案并形成印刷层，印刷的方式采用传统的柔性印刷，印刷的图案可以是防伪团花、潜影或者微缩文字等；在基层膜或者印刷层上设定区域的位置进行具有镭射效果的图案印刷形成一个镭射层，印刷的方式可以选择以下两种：一种为镭射压印；另一种为转移膜的转移，从而形成色彩炫动的幻彩效果，当镭射层设置在基层膜上时，印刷层和镭射层的印刷顺序不分先后，当镭射层设置在印刷层上时，先印刷印刷层，再制作镭射层，如果镭射层是彩色的，印刷层为彩色印刷；
在印刷层和镭射层上选择需要呈现金属光泽的区域，在其余区域涂覆水洗油墨形成水洗油墨层；在需要呈现金属光泽的区域和水洗油墨层上进行镀铝，形成镀铝层；对水洗油墨层进行水洗，洗除水洗油墨层以及镀在水洗油墨层上的镀铝层，直接镀在需要呈现金属光泽的区域的镀铝层留在印刷层和镭射层上，这样覆盖有镀铝层位置的防伪图案则呈现光泽效果或者透明可视的特殊效果。镭射层上一般镀设镀铝层，而印刷层上需要的区域也可镀设镀铝层。完成水洗后，对需要增加对比度的区域涂白。
通过上述工艺制作的防伪膜集合镭射效果和团花效果，成形多层的共体膜，实现高难度防伪。
上述防伪膜应用于印铁制罐，以下具体阐述下本实施例防伪膜的覆膜工艺：
在上述工艺制作而成的防伪膜的基层膜背面涂覆胶体，将所需覆膜的铁料加热至50~100度之间与防伪膜进行贴合，贴合后在放入50-100度之间的烘房进行72小时的熟化，使防伪膜贴牢在铁料上；
将所需覆膜的铁料加热至200~350度立即与防伪膜进行贴合，贴合后立即通过常温水辊进行冷却固化，使防伪膜贴牢在铁料上，使铁料成为覆膜的覆膜铁。该工艺覆膜的覆膜铁防伪膜贴附牢固，不容易起皱脱落。
将上述覆膜铁进行制罐、制桶，使桶罐身的色彩丰富，有较强的防伪效果，可以增加产品的市场竞争力。
上述实施例只为说明本发明的技术构思及特点，其目的在于让熟悉此项技术的人士能够了解本发明的内容并据以实施，并不能以此限制本发明的保护范围。凡根据本发明精神实质所作的等效变化或修饰，都应涵盖在本发明的保护范围之内。
