Description

超精细图案炫彩防水包装技术
技术领域
本发明涉及一种超精细印刷能变换7彩光泽的复合包装技术，特别是食品袋、面膜袋等多层复合袋子及防水胶盒
背景技术
1.现有的复合袋全部由2层或以上的薄膜复合而成，单层薄膜厚度一般在 0.02-0.06mm，世界上所有薄膜印刷全部采用凹印机或柔版印刷机印刷，凹印机和柔板印刷机都需要刻版，一般刻制铜板或树脂版，通过机械雕刻或者激光雕刻制版，无论何种方式制版，上述印刷机都无法印出字符高度低于0.3mm 的小字体和宽度小于0.05mm的线条，特别是图案复杂，套色数多的情况下，现有印刷技术套位不准，印刷质量很差，无法再现精细图文作品，更无法得到炫彩的印刷包装要求，市面上未出现任何一家能强烈反射七彩光泽的超精细(字体高度低于0.3mm)印刷的复合袋
2.现有的包装盒一般分为纸盒、纸塑盒、胶盒(PET盒\PP盒\PVC盒统称为胶盒)，能防水的盒子只有胶盒，截止到目前为止，市面上未出现任何一家整个包装盒版面反射七彩光泽且印刷精美的防水胶盒
发明内容
为了得到超精细炫彩(能反射七彩光泽)包装的效果，提高商品档次，本发明通过材料筛选、革新的复合工艺，创新的复合胶水，利用更先进的uv印刷机印刷，实现超精细、炫彩的防水包装效果。
技术方案：
选用纯铝箔遮光材料、素面镭射材料和薄膜进行多层复合，在素面镭射材料上涂布一层uv吸附涂层使得uv油墨能牢固的吸附在镭射层表面，利用创新的复合胶水与其他材料进行复合。复合完材料直接上uv印刷机印刷，实现牢固、超精细、炫彩的印刷效果
具体实施方法：
1.材料筛选：本发明的说明书附图中的图1，其中①+⑥+⑦为镭射膜，②为纯铝箔用于遮光，③为内膜，④为吸附油墨的涂层，⑤为印刷后的油墨层a. 镭射膜的选择：选用弹力系数小的PET⑥做镭射基材，在透明PET膜⑥上涂布镭射压纹层①，通过镭射模压机压制得到精细纹路的镭射，然后在压好的镭射基膜上镀铝得到镭射镀铝层⑦，使得镭射反射出耀眼的七彩光泽，如果不镀铝则整个镭射膜是透明状态，反光效果不好；镭射膜镀完铝后，上面再涂布一层能吸附uv油墨的涂层④镭射膜就大功告成了；b.遮光材料选择：对于需要避光保存的产品，选用纯铝箔膜②，不需要避光保存的产品此材料可省去；c.内膜的选择：如果要做面膜袋或者食品袋，则内膜③(直接接触产品的膜)用pe膜或pp膜；如果要做硬质塑胶盒子则选择厚度为0.35mm 或以上的PET/PVC/PP等材质作为内膜③；无论是制作袋子还是制作盒子，本发明只用到2-3层材料复合。
2.复合工艺：以上制作好的材料，经过电晕处理，再通过全新环保的聚氨脂胶水进行复合，晾干，等待印刷，注：如果复合前没有电晕或者电晕值错误，则复合容易产生气泡导致复合不均匀
3.印刷机的选择：印刷袋子卷材用ps版的uv转轮印刷机，制作包装盒用片材也使用PS版的uv印刷机。
4.电脑图文设计：将设计好的图文排版发给印刷机出版印刷，AI文件应该包括各种色彩信息、油墨数值信息，如果有专色还需要有专色信息、白油墨信息，图文设计中还含有超精细的防伪印刷信息，通过专业的图案图层设计达到美妙的七彩炫光的图文输出效果。
5.印刷制版：将设计好的图文转换成印刷机制版的文件，不需要经过菲林、晒版等工序，直接输出CTP版，从而得到超高精度的CTP版，CTP版为数字输出版，几乎无机械损失的再现，达到刻录光盘的刻录精度，能印刷出极为细小的文字，肉眼看不见的文字也可以印刷。
6.制袋或制盒。将印刷好的材料(卷材)用于切袋、制袋，或将印刷好的材料 (片材)用于制作胶盒
有益效果：
本发明采用优选的材料、先进的涂层技术、优选的复合工艺、革新的UV印刷机结合，得到超高精度的炫彩防水包装，用放大镜才能看出内部的神奇，产品呈现超高精度、炫彩的效果，包装直接上了一个新台阶，对于品牌商、包装厂尤为有利，肉眼看不见的极为细小的信息还可起到防伪作用，结合隐形油墨等其他防伪技术能得到令人难以置信的防伪效果；同时该发明只采用2-3层复合结构，比传统的制袋工艺简化很多，节省了雕刻铜版或柔版时间，也节约了制版费用，对于复杂精细的图案本发明极为有利。
附图说明
在本发明的说明书附图中，图1为本发明的复合材料结构示意图，其中①+⑥+⑦为镭射膜结构，⑥为镭射基材，①为镭射压纹层，⑦为镭射镀铝层，②纯铝箔，③为内膜，④为UV涂层，⑤为印刷后的油墨。
