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 渭 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.

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.

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.

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.

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.
