不干胶标签印刷粘度的检测方法?

现在好多产品上为了让用户更好的了解产品的用途及名称,不干胶标签就发挥出了其正常的作用,模内不干胶标签先要具备良好的印刷适性,保证油墨牢固地附于表面,在后加工过程要保证具备良好的加工适性,例如模切和冷烫金加工适性。接下来我们就来简单的了解下不干胶标签的滑动性。
Now many products in order to let users better understand the use and name of the product, the self-adhesive label has played its normal role. The in mold self-adhesive label should have good printability, ensure that the ink is firmly attached to the surface, and ensure good processing suitability in the post-processing process, such as die cutting and cold stamping. Next, let's have a simple understanding of the sliding of the label.
模内不干胶标签材料分为纸张和塑料薄膜两大类。前者遇水或受潮会变形,就会在一定程度上影响其正常的使用,但它的好处就是没有静电的干扰,可以减少吹瓶时吸取标签的损耗,另外它与塑料瓶子不是同质材料,不便于回收再利用。
In mold label materials are divided into paper and plastic film. The former will deform in case of water or damp, which will affect its normal use to a certain extent, but its advantage is that there is no interference of static electricity, which can reduce the loss of suction label when blowing bottles. In addition, it is not the same material as plastic bottles, which is not easy to recycle.
材料结构由印刷面、中间层和胶黏层组成,印刷面的作用是接受油墨,形成彩色图文;中间层支撑印刷面,给予材料足够的挺度和透明度,在印刷机上和高温作用下不变形保证套印准确。
The material structure is composed of printing surface, intermediate layer and adhesive layer. The function of printing surface is to receive ink and form color graphics; the intermediate layer supports the printing surface to give the material enough stiffness and transparency, which will not deform on the printing press and under the action of high temperature to ensure the accuracy of overprint.

不干胶标签的胶黏层表面主要有两种结构:平面无网纹结构和网纹结构。前者在使用时直接与毛坯接触,自然排气比较适合小面积的标签。后者在表面上压印了网纹结构,使用时气体通过网纹的排气通道排气,避免了气泡的生产。
There are two main structures on the surface of adhesive layer of self-adhesive label: plane non reticulated structure and reticulated structure. The former is in direct contact with the blank when using, and natural exhaust is more suitable for small area labels. The latter is embossed with reticulated structure on the surface, and the gas is vented through the reticulated exhaust channel to avoid the production of bubbles.
测试不干胶标签的印刷粘度并从衬纸表面撕下不干胶标签的正确方法是通过:保持标签尽可能直,并从顶端或底端的剥离衬纸,这可以确保标签很好地粘合到物体表面。
The correct way to test the printing viscosity of the self-adhesive label and tear off the self-adhesive label from the surface of the backing paper is to keep the label as straight as possible and peel off the backing paper from the center of the top or bottom end, which can ensure that the label adheres well to the surface of the object.
有些粘合剂会与特定物质发生化学反应。比如印刷不干胶标签作为标签,在一定条件下会污染一些特殊面料。一些需要短期粘性的标签在曝光条件下会产生长期粘性。另一方面,一些需要有附着力的标签会在一些表面失去附着力。
Some adhesives react with certain substances. For example, printing self-adhesive labels as labels will pollute some special fabrics under certain conditions. Some labels that need short-term stickiness will produce long-term stickiness under exposure conditions. On the other hand, some labels that need adhesion will lose adhesion on some surfaces.
使用不干胶标签在再生纸表面打印标签和其他标签时,经常会出现问题。纸张在循环加工过程中有许多不同的种类,其中一些会被硅或蜡涂层污染,因此混合加工会污染的回收产品。当标签用在这些被污染的再生纸表面时,胶粘剂往往会失去作用效应,注意:不干胶标签中硅胶涂层的作用效应,确保不干胶能很容易地从底纸上分离。
When using self-adhesive label to print labels and other labels on the surface of recycled paper, problems often occur. There are many different kinds of paper in the recycling process, some of which will be polluted by silicon or wax coating, so mixed processing will pollute the recycled products. When the label is used on the surface of these polluted recycled paper, the adhesive will often lose its effect. Note: the effect of silicone coating in the self-adhesive label ensures that the self-adhesive can be easily separated from the backing paper.
