不干胶标签材料知识概述!

来源:http://www.jindingyinshua.com   日期:2019-03-20

不干胶标签是目前应用普遍的标签,但它的构造并不简单。典型的不干胶标签由五层组成,包括:

  Self-adhesive label is the most widely used label at present, but its structure is not simple. Typical adhesive labels consist of five layers, including:
  一层——外表资料,或称原料,用于记载或印刷图文信息。
  The first layer, appearance data, or raw materials, is used to record or print graphic information.
  第二层——底漆,或称增粘涂层,能够使粘合剂和外表资料更严密地分离。底漆同时也有避免化学试剂浸透的作用,否则化学试剂可能会从底下的三层浸透过来,弄脏标签外表。另外,彩色底漆也可用作透明外表资料的背景。
  The second layer, primer, or tackifier coating, enables a closer separation of adhesives and appearance data. Primer also has the effect of avoiding chemical reagent immersion, otherwise the chemical reagent may be immersed from the bottom three layers to dirty the label appearance. In addition, color primers can also be used as backgrounds for transparent appearance data.
  第三层——标签的胶粘剂。在撕去标签外表衬纸、将标签贴到某物体外表之前,胶粘剂将外表资料与涂有硅树脂的衬纸别离开。
  Layer 3 - Adhesive for labels. Before tearing off the outer lining of the label and pasting the label on the surface of an object, the adhesive keeps the appearance information away from the silicone-coated lining.
  第四层——硅树脂涂层,用于确保标签与衬纸容易分开。
  The fourth layer, silicone coating, is used to ensure that labels and linings are easily separated.
  第五层——衬纸,维护标签在运用前不被粘污,通常由漂白或原色的Kraft纸(偶然也会用洁净的聚酯资料)加工而成。衬纸还有支撑的作用,保证在处置标签的过程中,标签不会弯曲或卷曲。
  Layer 5 - Paper lining, which maintains that the label is not dirty before use, is usually made of bleached or pristine Kraft paper (occasionally clean polyester material). Paper lining also serves as a support to ensure that the label does not bend or curl in the process of handling the label.
  固然不干胶标签用处普遍,深受大家欢送,但它不是在任何环境下都能适用。例如,在冷冻食品包装和其他高速操作时,采用热封标签更为、经济。
  Although the non-sticker label is widely used and welcomed by everyone, it can not be applied in any environment. For example, in frozen food packaging and other high-speed operations, the use of heat-sealed labels is more efficient and economical.
  粘性测试的重要性
  Importance of Viscosity Testing
  不同类型的不干胶标签在运用之前,测试胶粘剂的类型是很重要的,看看这种胶粘剂是属于不干胶,热封胶还是涂胶水纸。有些胶粘剂会与特定物质发作化学反响。例如,用作标牌的不干胶标签在特定条件下会污染某些特殊的织物。有些需求短暂粘性的标签在曝光条件下会产生耐久的粘性。而另一方面,某些需求有耐久粘性的标签在某些外表却会失去粘性。
  It is important to test the type of adhesives for different types of non-drying labels before they are used. See if the adhesives belong to non-drying adhesives, heat sealants or glued paper. Some adhesives react chemically with specific substances. For example, non-drying glue labels used as labels can contaminate certain special fabrics under certain conditions. Some labels that require temporary stickiness produce durable stickiness under exposure conditions. On the other hand, some labels with durable stickiness will lose stickiness in some appearances.

  在再生纸的外表运用不干胶标签和其他标签时,经常会呈现问题。在停止循环加工的过程中有多种不同纸张,有些纸张会被硅或蜡的涂层污染,这样混合加工就污染了终的再消费品。在这些被污染的再生纸外表运用标签时,胶粘剂常常会失去作用。留意:不干胶标签中硅树脂涂层的作用是确保不干胶容易地脱离衬纸。
  Problems often arise when self-adhesive labels and other labels are used on the surface of recycled paper. There are many different kinds of paper in the process of stopping recycling. Some paper will be contaminated by the coating of silicon or wax, so the mixed processing will contaminate the final consumer goods. Adhesives are often ineffective when labeling the appearance of contaminated recycled paper. Note: The role of silicone coatings in sticker labels is to ensure that the sticker is easily detached from the lining.
  温渡过低也会招致问题发作。低温降低了粘结的速度,在胶粘剂粘牢外表之前,标签可能曾经从外表剥落下来了。假如标签贮存不当——环境温差大,湿度动摇大,或者堆放不当——标签运用之后很快会失去粘性。
  Low temperatures can also cause problems. Low temperatures reduce the speed of bonding, and the label may have peeled off the surface before the adhesive adheres to the surface. If the label is stored improperly --- the ambient temperature difference is large, the humidity is shaken, or the stacking is improper --- the label will lose its stickiness soon after it is used.
  有效运用不干胶标签的主要要素之一是正确地将不干胶从衬纸外表剥开。
  One of the most important factors in the effective use of sticker labels is to peel the sticker from the outside of the lining paper correctly.
  很多人都错误的从标签左角或右角揭开拉下,这样会削弱接触局部不干胶的粘性,而且还会毁坏资料中的“外表纤维”,使标签卷曲。
  Many people mistakenly pull the label from the left or right corner, which will weaken the stickiness of contact with local adhesive, but also destroy the "external fibers" in the data, making the label curl.
  从衬纸外表扯开不干胶标签的正确办法是:尽量坚持标签的平直,从顶端或底端的中心剥开衬纸,能够保证标签很好地粘结到物体外表。
  The correct way to tear off the sticker label from the outside of the liner is to stick to the straightness of the label as far as possible and peel the liner from the center of the top or bottom to ensure that the label sticks well to the outside of the object.
