山东透明不干胶标签印刷模切溢出如何解决

来源:http://www.njhxsfs.com/ 日期:2019-08-12 发布人:admin   模切溢流是指标签模切后,标签边缘出现溢胶现象,是胶粘剂产品常见的一种缺陷。溢出会导致标签外观缺陷、印刷污染、剥落等问题。
  Die-cutting overflow refers to the phenomenon of glue overflow at the edge of the label after die-cutting, which is a common defect of adhesive products. Overflow will lead to label appearance defects, printing pollution, peeling and other issues.
  不干胶标签材料是一种夹芯结构的粘胶制品,标签模切用背纸,切断表面材料和粘胶,并将标签材料和粘胶的形状从纸的底部切下。
  Self-adhesive label material is a kind of viscose product with sandwich structure. Back paper is used for label die cutting. Surface material and viscose are cut off, and the shape of label material and viscose is cut off from the bottom of the paper.
  不干胶标签的包装分为卷筒包装和平面包装,除轮胎标签等特殊标签外,卷筒标签的成品中大多出现数字模切溢出。轧制和平板标签的加工和包装方法不同,导致轧制标签容易受到较多的摩擦和挤压张力。
  The packaging of adhesive labels is divided into drum packaging and flat bread packaging. Except for the special labels such as tire labels, most of the products of drum labels have digital die cutting overflow. The different processing and packaging methods of rolling and plate label make the rolling label vulnerable to more friction and extrusion tension.

  不干胶标签材料分为丙烯酸树脂基材和橡胶基材两大类,都是压敏粘胶,粘胶必须具有一定的厚度和弹性,在高温、高湿和压力条件下必然会变形。因此,有必要从标签的加工和储存环境,如温度、湿度、压力等方面分析胶溢出的原因。
  Self-adhesive label materials are divided into two categories: acrylic resin and rubber. They are pressure-sensitive adhesives. The adhesives must have certain thickness and elasticity, and will inevitably deform under high temperature, high humidity and pressure. Therefore, it is necessary to analyze the causes of glue spillover from the aspects of label processing and storage environment, such as temperature, humidity and pressure.
  根据生产工艺,正确选择和使用胶粘剂材料
  Correct selection and use of adhesives according to production process
  选择胶粘剂前需咨询供应商明确胶粘剂类型、胶粘剂加工性能。胶粘剂的流动性越大,越容易产生溢流。温度越高,胶粘剂的流动越好,初始粘度越大。但高温、高湿的环境会使胶粘剂的流量大大增加,所以夏季、雨季是溢胶季的问题。溢胶问题的出现与涂层的粘结也有着密切的关系。例如,轮胎标签的胶粘剂涂布量比较大,所以也容易溢出(虽然在胶粘剂中已经添加了阻流剂)。冬季和夏季胶粘剂涂布量应有所不同,这是对漆膜表面材料较为敏感的一种。由于冬季和夏季胶粘剂的配方是不同的,所以不应该用在错误的季节里,和不应该长期积累的粘合剂材料和标签,应尽量减少库存,根据“先进先出”的原则使用粘合材料。
  Before choosing adhesives, consult suppliers to clarify the type of adhesives and the processing properties of adhesives. The greater the fluidity of adhesives, the easier the overflow will occur. The higher the temperature, the better the flow of the adhesives and the higher the initial viscosity. However, the high temperature and humidity environment will greatly increase the flow of adhesives, so summer and rainy season are the problem of overflow season. The occurrence of glue overflow is also closely related to the bonding of coatings. For example, the amount of adhesives coated on tire labels is relatively large, so it is easy to spill over (although flow blockers have been added to the adhesives). The amount of adhesives applied in winter and summer should be different, which is one of the sensitive materials to the surface of paint film. Because the formulation of adhesives is different in winter and summer, they should not be used in the wrong season, and should not accumulate adhesives materials and labels for a long time. They should minimize inventory and use adhesives according to the principle of "first in first out".
  标签处理和存储环境
  Label Processing and Storage Environment
  温度过高容易造成不干胶标签溢出,因此,在夏季生产不干胶标签时,保持车间内适当的温度尤为重要。标签加工和贮存环境温度应控制在23℃- 3℃,相对湿度应控制在55% - 5%,过高的温度或湿度会改善胶粘剂的流动。
  Excessive temperature can easily cause sticker label overflow, so it is particularly important to maintain the appropriate temperature in the workshop during the production of sticker labels in summer. The temperature of label processing and storage environment should be controlled at 23 - 3 C, and the relative humidity should be controlled at 55% - 5%. Excessive temperature or humidity will improve the flow of adhesives.

  不干胶标签模切质量控制
  Quality Control of Die Cutting of Non-adhesive Label
  必须用锋利的工具进行模切,钝边会造成标签胶黏剂过度拥挤,导致模切标签过程中边缘溢出。模切压力过大也会对标签胶造成过大的压力,而模切压力过小可能会导致模切过程中胶粘剂拉丝,使标签在边缘或表面溢出。
  It is necessary to use sharp tools for die cutting. Blunt edges will cause excessive crowding of label adhesives and lead to edge overflow in the process of die cutting label. Excessive die-cutting pressure can also cause excessive pressure on the label glue, and too low die-cutting pressure may lead to adhesive wire drawing during die-cutting process, which causes the label to overflow on the edge or surface.

  不干胶标签加工技术控制
  Technology Control of Non-adhesive Label Processing
  应该避免的存在滑动摩擦标签贴纸处理的过程中,因为有滑动摩擦标签胶的部分容易积累,从而形成一个污染贴纸边缘,在这种情况下,标签上溢出位置将显示一个明显的规则和方向。
  The existence of sliding friction label stickers should be avoided, because the sliding friction label stickers are easy to accumulate, thus forming a contaminated sticker edge. In this case, the spillover position on the label will show a clear rule and direction.

  不干胶标签收卷张力控制
  Tension control of unwinding of adhesive label
  收卷张力过大会导致标签胶过度挤出,甚至会导致标签在纸的底部打滑,导致胶水溢出。非方标签由于收卷张力在轴向不一致,容易造成局部张力过大,形成不干胶标签局部溢出。小方标签,由于承受的压力相同,承受的压力较大,也容易出现标签溢胶的现象。
  Too much winding tension will result in excessive extrusion of label glue, which may even cause the label to slip at the bottom of the paper, leading to glue overflow. Non-square labels tend to cause local tension to be too large due to the inconsistent winding tension in the axial direction, resulting in local overflow of non-adhesive labels. Small square labels, because of the same pressure, bear greater pressure, but also prone to label overflow phenomenon.
  除上述原因外,正确选择合适的胶粘剂材料也非常重要。贴纸材料选择、终端应用、供应商选择分析,以使您获得最具性价比的产品。
  In addition to the above reasons, it is also very important to select the right adhesive materials. Sticker material selection, terminal application, supplier selection analysis, so that you can get the most cost-effective products.
  标签材料供应商选择
  Selection of Label Material Suppliers
  竞争是质量、服务、品牌的全方位竞争,但归根结底是实力的竞争。供应商的选择主要从供货能力、产品质量和批次稳定性、价格、服务和研发能力、潜在的市场开拓能力和洞察力、改进速度等方面进行评价。一家稳定而致力于长期发展的供应商正致力于印刷企业的发展,最终用户,始终完善自己,为客户增加附加值而不断努力。为印刷企业提供合适的产品应用、相关技术支持、生产过程控制建议和改进方案。
  Competition is the all-round competition of quality, service and brand, but in the final analysis, it is the competition of strength. The selection of suppliers is mainly evaluated in terms of supply capability, product quality and batch stability, price, service and R&D capability, potential market development capability and insight, and improvement speed. A stable and long-term development supplier is committed to the development of printing enterprises, end users, always improve themselves, add value to customers and constantly strive. Provide suitable product application, related technical support, production process control suggestions and improvement programs for printing enterprises.
  选择性价比最好的产品不仅关乎产品本身,还关乎由最好的供应商提供的最好的产品。例如,有了较好的印刷设备,不干胶印刷企业,如果选择便宜但不稳定的产品,就不能发挥其印刷设备的特点;同样,质量低劣或不合适的产品应用于一台好的印刷机,并不比一块新布应用于一件旧衣服更有效。
  Selective products with the best price ratio are not only about the product itself, but also about the best products provided by the best suppliers. For example, with better printing equipment, non-adhesive printing enterprises can not give full play to the characteristics of their printing equipment if they choose cheap but unstable products; similarly, the application of inferior or inappropriate products to a good printing press is no more effective than that of a new cloth to an old clothing.
  因为不干胶标签材料的产品有一定的磁滞回线,从贴好标准的货架上或消费者手中总是有一段时间,安全是很难坚持,但是整体实力和质量控制能力不是完整的供应商所提供的产品将使应用程序变得不可靠,有风险。
  Because the products of non-sticky label materials have certain hysteresis loops, it is always a period of time from the shelves or consumers with standard stickers. Safety is very difficult to adhere to, but the overall strength and quality control capability of products provided by incomplete suppliers will make the application unreliable and risky.
