What are the requirements of the labeling machine for labels?

Shanghai Shenggang automatic self-adhesive labeling machine is mainly used for labeling the self-adhesive surface of various round bottles.
It adopts servo motor for labeling, imported optical fiber detection, stable labeling and high precision, and a thermal coding machine is installed.
Print the production date, batch number and shelf life, etc.
The automatic self-adhesive labeling machine has protection functions such as automatic alarm function for lack of labels, and is manufactured in full accordance with GMP standards
.

Widely used in pharmaceutical, food and chemical industries
.

 The automatic labeling machine should have the following points for the label: (1) The backing paper is also an important indicator to control the automatic labeling
.

It is required that the surface of the backing paper is uniformly coated with silicon, and the release force is consistent; the thickness is uniform, and it has good tensile strength to ensure that the label does not break; the thickness is uniform, and it has good light transmittance to ensure that the sensor can correctly identify the position of the label
.

(2) Processing quality It is required that both sides of the backing paper are flat and free of cracks after slitting, so as to avoid the backing paper from breaking when the tension changes
.

When die-cutting, it is necessary to avoid cutting through the backing paper or destroying the silicon-coated layer.
If the backing paper and the silicon-coated layer are damaged, the backing paper is easily broken or the adhesive in the label penetrates into the backing paper, causing no labeling and tearing of the backing paper.

.

In addition, the static electricity in the roll paper label should be eliminated before labeling, because static electricity will cause the label to not be labeled or the label to be inaccurate
.

 　　(3) Release force, also known as peel force, is the force when the label is released 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 backing paper, as well as the ambient temperature during labeling
.

If the release force is too small, the label is easy to fall off during the conveying process (detached from the liner); if the release force is too large, it is difficult for the label to detach from the liner, and the label cannot be issued
.

Various technical indicators should be comprehensively controlled to keep the release force within a reasonable range
.

 　　(4) The firmness of the surface material label is the key to the labeling, so a certain strength and hardness of the surface material are required, and the firmness of the label is related to the thickness of the material and the area of ​​the label, so when using a soft film material, appropriate Increase its thickness, generally controlled above 100μm
.

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 tag guns
.

The poor firmness of the label will cause the label to not be labeled during labeling, or the label will be rewound with the backing paper, making the automatic labeling invalid
.
