General round bottle automatic labeling machines have requirements for labels: (1) Surface material round bottle automatic labeling machine label stiffness is the key to the label, so it requires a certain strength and hardness of the surface material, and the stiffness of the label depends on the material. The thickness of the label is related to the area of u200bu200bthe label, so when using a soft film material, the thickness should be appropriately increased, generally controlled above 100μm. Thin paper materials, such as 60~70g/m2 labeling paper, are generally not suitable for making large labels, but suitable for processing into small labels, such as price labels used on price guns. Poor stiffness of the label will cause the label not to be issued during labeling, or the label will be rewinded with the backing paper, which will make the automatic labeling of the round bottle automatic labeling machine invalid. (2) Release force, also called peeling force, is the force when the label is separated from the backing paper. The release force is related to the type and thickness of the adhesive and the silicon coating on the surface of the bottom paper, as well as the ambient temperature during labeling. If the release force is too small, the label will easily fall off (leave the bottom paper) during the conveying process; if the release force is too large, it will be difficult for the label to detach from the bottom paper and the label cannot be released. Various technical indicators should be comprehensively controlled to keep the release force within a reasonable range. (3) Bottom paper is also an important index to control the automatic labeling machine for round bottles. It is required that the surface of the bottom paper is coated with silicon uniformly and has the same release force; uniform thickness and good tensile strength to ensure that it does not break when labeling; uniform thickness and good light transmittance to ensure that the sensor correctly recognizes the position of the label. (4) Processing quality. After slitting, both sides of the bottom paper are required to be flat and free of breaks to avoid the bottom paper from breaking when the tension changes. Avoid cutting through the bottom paper or destroying the silicon-coated layer during die-cutting. If the bottom paper and the silicon-coated layer are damaged, the bottom paper may be broken or the adhesive in the label will penetrate into the bottom paper. . In addition, the automatic round bottle labeling machine must eliminate static electricity in the roll paper label before labeling, because static electricity will cause the label not to be displayed or inaccurate when labeling.
