Sticker printing, are the stickers self-adhesive? 【Self-adhesive stickers】

Sticker printing is also self-adhesive printing.

Adhesive printing is one of the common labels, and there are many kinds of labels made with self-adhesive.

Self-adhesive labels are usually used to identify goods, such as barcode labels, laser anti-counterfeiting labels, color labels, etc. Self-adhesive labels are categorized by user. Common ones are supermarket labels (shopping mall labels), logistics labels (barcode labels on product boxes), food labels, and drug labels.

Compared with traditional labels, self-adhesive stickers have the advantages of no need for gluing, no paste, no need to dip, zero pollution, and greatly saves labeling time. , the use of a wider range, more convenient and quick. All kinds of self-adhesive stickers can be used in materials that ordinary paper labels cannot use. Self-adhesive stickers are usually printed and processed on a label linkage machine, and multiple processes are realized at one time, such as graphic printing, die-cutting, waste discharge, slitting and rewinding.

1. The self-adhesive stickers should be flat, and the winding tension should be uniform.

The self-adhesive label should be uniform, and the winding tension should be uniform. The flatness is good, and it can be transferred, moved, registered and rolled normally during the printing process. The film tension during winding must be uniform and appropriate. If the tension is too low, the film material will sag, and the vertical and horizontal printing will be inaccurate; if the tension is too high, the media will shrink horizontally, the printing will be unstable, and normal printing will not be possible. 2. No 2. The thickness of the dry glue sticker should be consistent, and the strength index should meet the standard.

The thickness of the sticker must be the same, and the strength index must meet the standard. The printing pressure generated during the printing process is closely related to the thickness of the label. If the thickness is not uniform, the printing pressure will also be uneven, resulting in darker or lighter writing or light ink on the label. If the film strength is low, the tension of the film during printing cannot be controlled, which can greatly affect die cutting and waste disposal.

3. Consider the environment and user's requirements comprehensively

It depends on the type of self-adhesive label object, grade, product quality, characteristics of the self-adhesive surface layer, application environment and user requirements. If the transparent PP self-adhesive is attached to the transparent bottle, it can create a sense of fashion without labels, improve the quality of the product, and stimulate consumers' desire to buy.
