不干胶粘性不牢固的原因,你了解吗?

来源:http://www.shengfengyinshua.com/ 日期:2018-09-11 发布人:admin 经常有客户咨询说不干胶标签粘性不牢固,这原因是复杂的,有些不明就里的客户,还说是我们的材料有质量问题,事实上是:我们所采用的材料均是来自知名厂商的材料,不存在质量问题,但有可能客户没有讲清粘性要求,或没有在大批量贴前,做试贴实验,有可能导致粘性没有达到理想要求,现结合多年经验整理汇集如下问题症结所在,以供参考:
Often the customer consults that the stickiness of adhesive labels is not strong, this is because of the complexity, some unknown customers, but also said that our materials have quality problems, in fact, we are using materials from well-known manufacturers, there is no quality problem, but it is possible that customers did not specify the stickiness requirements. Or not in a large number of paste before the test, may lead to viscosity does not meet the desired requirements, is now combined with years of experience to collate the following problems for reference:
一、标签边缘起翘、标签起泡、褶皱的原因分析与对策
First, the causes of the edge of the label is raised, the blister and wrinkle are analyzed and the countermeasures are put forward.
1、贴标压力过小或接触不良,检查手工贴标过程或自动贴标工艺确保贴实
1, labeling pressure is too small or contact is not good, check manual labeling process or automatic labeling process to ensure that it is appropriate.
2、面材选择不当,换用薄型或软质面材
2, improper selection of surface material, replace thin or soft surface.
3、基材表面残留化学品或潮湿,注意包装材料贴标前清洁工艺及干燥
3. Residual chemicals or moisture on the surface of the substrate. Attention should be paid to the cleanliness and drying of the packaging materials before labeling.
4、贴标温度或温度不适宜,注意所选择粘胶剂特性,避免低温下操作
4, labeling temperature or temperature is not suitable, pay attention to the characteristics of the selected adhesive, avoid low temperature operation.
5、粘胶剂选择不当, 注意供应商产品选择推荐及用途
5, improper selection of adhesive, pay attention to supplier selection, recommendation and use.
二、小口径标签起翘或90°直角起拱的原因分析与对策
Two, small caliber label or 90 degree right angle arching reason analysis and Countermeasures
1、面材选择不当,换用薄型或软质面材
1, improper selection of surface material, replace thin or soft surface.
2、粘胶剂选择不当
2. Improper selection of adhesive.
3、公分直径以下小口径标签和小型包装及90直角设计的标签建议咨询且先做实验
透明不干胶标签印刷厂家
3. Consult and do the experiment first for small caliber label and small package and 90 right angle design label
三、标签脱落、不粘的原因分析与对策
Three, cause analysis and Countermeasures of label falling off and non sticking
1、标签在使用前储存条件不当导致失效,注意供应商产品储存及保质期说明
1. Labels fail to be stored properly before use. Attention should be paid to the storage and shelf life of the suppliers.
2、基材表面潮湿、粗糙或残留化学品, 注意包装材料贴标前清洁工艺及干燥
2. Wet, rough or residual chemicals on the surface of the substrate. Pay attention to the cleaning process and drying of the packaging materials before labeling.
3、胶粘剂选择不当, 注意供应商产品选择推荐及用途
3, improper selection of adhesive, pay attention to supplier selection, recommendation and use.
四、自动贴标时出现飞标或不出标的原因分析与对策
Four, analysis and Countermeasure of flying mark or no mark when automatic labeling.
剥离力太低或太高,根据自动贴标速度并选用合格的配套材料。另外,不干胶标签因材料品质、印制工艺不同而影响使用效果,尽量选用高品质标签。
The stripping force is too low or too high, according to the speed of automatic labeling and the selection of qualified supporting materials. In addition, because of the different material quality and printing process, the use of non-sticker labels will be affected, and high-quality labels will be selected as far as possible.
为求稳妥,我们真诚建议各位朋友在定制标签前,请先行实验测试不干胶样纸。以确保产品的完美性。不干胶耐低温和高温的使用标准及存放期限的标准应用:
In order to be safe, we sincerely recommend that friends in customizing the label, please first test the adhesive sample paper. To ensure the perfection of products. Application standards and storage time limits for low temperature and high temperature applications of stickers:
印刷及加工: 适合用于凸版、胶印、柔性版、丝网及烫金等多种印刷工艺进行单色及彩色印刷。适合卷筒到单张及单张印刷。在进行油墨干燥时,印刷工位的温度可达到80°C,但在到达排废工位时,温度需保持在50°C以下。
Printing and processing: suitable for relief, offset, flexible plate, screen and bronzing and other printing processes for monochrome and color printing. Suitable for reel to sheet and sheet printing. During ink drying, the temperature of the printing station can reach 80 C, but it should be kept below 50 C when it reaches the waste discharge station.
储存期: 在温度23°C、相对湿度50%的情况下,可储存三年。
Storage period: at 23 degrees C and relative humidity 50%, it can be stored for three years.
此产品需在用户的使用环境中测试,才能判定其是否满足特殊的贴标需求。技术数据及建议基于实验结果,不视作担保或保证 影响不干胶粘性的因素有许多种,如:使用环境和贴标方式,是否需要耐高温或者耐低温,所应用的环境是否极端恶劣等等,上述因素必须要了解,如果不清楚往往你的不干胶材质是较好的,也会造成客户说材质不好,所以经常有些客户在咨询时说他们现在所用的不干胶标签粘性不牢固,粘性远远达不到他们的要求,其实可能是客户没有讲清粘性要求,或者所售人员没有问清楚而造成的,或者说客户没有在大批量贴前,做试贴实验,有可能导致粘性没有达到理想要求等等。
The product needs to be tested in the user's environment to determine whether it meets the special labeling requirements. Technical data and recommendations are based on experimental results and are not considered guaranteed or guaranteed to affect the stickiness of non-drying adhesives. There are many factors, such as: the use of the environment and labeling methods, whether high or low temperature resistance is required, whether the applied environment is extremely bad, and so on. Material is the best, it will also cause customers to say that the material is not good, so often some customers in the consultation that they are using sticky adhesive labels are not strong, sticky far below their requirements, in fact, may be the customer did not clarify the sticky requirements, or the sales staff did not ask clearly and caused, or lobbyist Users do not paste a large number of experiments, may lead to stickiness does not meet the desired requirements and so on.
不同类型的不干胶标签在使用之前,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溶胶还是涂胶水纸。有些胶粘剂会与特定物质发生化学反应。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。有些需要短暂粘性的标签在曝光条件下会产生持久的粘性。而另一方面,某些需要有持久粘性的标签在某些表面却会失去粘性。
It is important to test the type of adhesive before using different types of adhesive labels to see whether the adhesive is a non-drying thermosol or a coated paper. Some adhesives react with specific substances. For example, the adhesive labels used as signs will contaminate certain special fabrics under certain conditions. Some labels requiring short stickiness will produce persistent viscosity under exposure conditions. On the other hand, some labels with persistent viscosity will lose stickiness on some surfaces.
在再生纸的表面使用不干胶标签和其他标签时,经常会出现问题。在进行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较终的再生产品。在这些被污染的再生纸表面使用标签时,胶粘剂往往会失去作用。注意: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 using stickers and other labels on the surface of recycled paper. There are many different types of paper in the recycling process, some of which are contaminated by silicon or wax coatings, so that the final recycled product is contaminated by the blending process. When using labels on the surface of the contaminated recycled paper, the adhesive often loses its function. Note: the role of silicone resin coating in self-adhesive labels is to ensure that the adhesive is easily separated from the lining paper.
温度过低也会导致问题发生。低温降低了粘结的速度,在胶粘剂粘牢表面之前,标签可能已经从表面剥落下来了。如果标签储存不当——环境温差大,湿度波动大,或者堆放不当——标签使用之后很快会失去粘性。
Too low temperatures can also cause problems. Low temperatures reduce the bonding rate, and the label may have peeled off the surface before the adhesive binds to it. If the labels are not stored properly - ambient temperature variations, humidity fluctuations, or improper stacking - the labels quickly lose their stickiness after use.
有效使用不干胶标签的较主要因素之一是正确地将不干胶从衬纸表面剥开。很多人都错误的从标签左角或右角揭开拉下,这样会减弱接触部分不干胶的粘性,而且还会破坏材料中的“表面纤维”,使标签卷曲。
One of the most important factors in the effective use of self-adhesive labels is to correctly remove the adhesive from the lining paper surface. Many people mistakenly pull the label from the left or right corner, which will weaken the stickiness of the contact part of the adhesive, but also destroy the "surface fiber" in the material, making the label curl.
从衬纸表面撕开不干胶标签的正确方法是尽量保持标签的平直,从顶端或底端的中心剥开衬纸,可以保证标签很好地粘结到物体表面。
The correct way to tear the non-adhesive label from the lining surface is to keep the label as straight as possible. Peeling the lining from the center of the top or bottom can ensure that the label is well bonded to the surface of the object.
