The invention discloses an anti-counterfeiting process of an aluminized film printed open-and-close drawing line, which comprises the following steps: first, two-sided corona treatment is carried out on the base film layer, and then one side of the base film layer is aluminized; second, the printing toner is added into the PET varnish and mixed evenly to obtain the first product, and the first product is adopted. Print the aluminized surface to get the printing layer; Step 3, wash the printing layer with aluminium washer, then coat the non-aluminized surface of the base film with anti-sticky liquid and print, coat the aluminized surface with non-adhesive, and then roll up, aging treatment and cutting. When the outer package is opened, two different patterns are shown inside and outside the opening and closing cable, thus achieving the effect of anti-counterfeiting; the two-dimensional code or symbol with anti-counterfeiting information on the package can be protected by using the shading property of the aluminized film, and the two-dimensional code information or symbol can be seen after the opening, and the anti-counterfeiting label can be pulled without adding other anti-counterfeiting labels. Line anti-counterfeiting design and combination anti-counterfeiting design.
【技术实现步骤摘要】
一种镀铝膜印刷型拆封拉线的防伪工艺
本专利技术涉及镀铝膜印刷型拆封拉线领域,具体是一种镀铝膜印刷型拆封拉线的防伪工艺。
技术介绍
镀铝膜是通过真空镀铝工艺将高纯度的铝丝在高温(1100-1200摄氏度)下蒸发成气态,之后塑料薄膜经过真空蒸发室时,气态的铝分子沉淀到塑料薄膜表面而形成的光亮金属色彩的薄膜。由于它既具有塑料薄膜的特性,又具有金属的特性,是一种廉价美观、性能优良、实用性强的包装材料。目前应用最多的镀铝薄膜主要有聚酯镀铝膜(VMPET)和CPP镀铝膜(VMCPP)。薄膜表面镀铝的作用是遮光、防紫外线照射,既延长了内容物的保质期,又提高了薄膜的亮度,从一定程度上代替了铝箔,也具有价廉、美观及较好的阻隔性能,因此,镀铝膜在复合包装中的应用十分广泛,目前主要应用于饼干等干燥、膨化食品包装以及一些医药、化妆品的外包装上。镀铝膜作为基膜进行印刷分切加工时需要采用拆封拉线,现有的拆封拉线从内往外依次包括不干胶层、印刷层、基膜层、镀铝层、印刷层、文字层和防粘层,这种结构的拆封拉线的防伪效果不好,这就为生产者带来了困扰。
