表面材料Surface material：

标签的坚挺度是出标的关键，因此要求表面材料的一定的强度和硬度，标签的坚挺度又和材料的厚度和标签的面积有关，所以使用柔软的薄膜材料时，要适当增加其厚度，一般控制在100μm以上。薄的纸张类材料，如60~70g/m2的贴标纸，一般不适合做大标签，而适合加工成小标签，如标价枪上使用的价格标签。标签的坚挺度差会导致贴标时不出标，或标签同底纸一同复卷，使自动贴标失效。The strength of the label is the key to marking, so it requires a certain strength and hardness of the surface material. The strength of the label is related to the thickness of the material and the area of the label. Therefore, when using a soft film material, the thickness of the label should be appropriately increased and generally controlled to be over 100 μ m .. Thin paper materials, such as 60 - 70g / m2 labeling paper, are generally not suitable for large labels, but are suitable for processing into small labels, such as price labels used on price guns. The difference in the strength of the label will cause the label not to be labeled, or the label will be rewound together with the base paper, making the automatic label invalid.

离型力Release force

也称剥离力，是标签脱离底纸时的力。离型力与粘合剂的种类、厚度及底纸表面的涂硅情况有关，还和贴标时的环境温度有关。离型力太小，标签在输送过程中容易掉标(脱离底纸);离型力太大，标签脱离底纸困难，无法出标。应综合控制各项技术指标，使离型力在一合理的范围内。Also known as peeling force, it is the force when the label is separated from the base paper. The release force is related to the type and thickness of the adhesive and the silicon coating on the surface of the backing paper, as well as the ambient temperature at the time of labeling. The release force is too small and the label is easy to fall off ( off the base paper ) during the conveying process. The release force is too great to release the label from the base paper. All technical indexes should be comprehensively controlled so that the parting force is within a reasonable range.

标签底纸Label backing

是控制自动贴标的重要指标。要求底纸表面涂硅均匀，离型力一致;厚度均匀，有好的抗拉强度，确保贴标时不断裂;厚度均匀，有好的透光性，确保传感器正确识别标签的位置。It is an important index to control automatic labeling. It is required that the surface of the backing paper be uniformly coated with silicon and the parting force be consistent. Uniform thickness and good tensile strength ensure no breakage during labeling. Uniform thickness and good transparency ensure that the sensor correctly identifies the position of the label.

加工质量Processing quality

分切后底纸两侧平整、无破口，避免张力变化时底纸断裂。模切时要避免切穿底纸或破坏涂硅层，底纸和涂硅层被破坏容易出现底纸拉断或标签内的粘合剂渗入底纸，出现不出标和撕裂底纸现象。此外，在贴标前要消除卷筒纸标签内的静电，因为静电会造成贴标时不出标或出现贴标不准的现象。After slitting, the two sides of the base paper are flat and free of crevasses, so as to prevent the base paper from breaking when the tension changes. During die - cutting, it is necessary to avoid cutting through the base paper or damaging the silicon-coated layer. When the base paper and the silicon-coated layer are damaged, the base paper will be easily broken or the adhesive in the label will penetrate into the base paper, resulting in no label and tearing of the base paper. In addition, the static electricity in the web label should be eliminated before labeling, because static electricity will cause the label not to be labeled or the label not to be labeled correctly.

贴标机翘标现象的解决方法 贴标中要达到完美视觉效果。其中之一就是避免贴标中的翘标现象。在管子未灌装之前贴标，贴好以后再进行灌装封尾，而在封尾过程中的加热对标签的考验尤其严峻，标签距离底端越近，翘标的可能性就越大。The Solution to the Warping Phenomenon of Labeling Machine The perfect visual effect should be achieved in labeling. One of them is to avoid warping in labeling. Labeling before the pipe is not filled, filling and closing the end after it is pasted, and the heating in the closing process is especially severe for the label, and the closer the label is to the bottom, the more likely it is to become warped.
