In recent years, the demand for various self-adhesive label printing products in the domestic printing market has continued to increase, especially in some commercial circulation fields for self-adhesive label printing products. Adhesive label printing products have a very significant feature, that is, fine graphics and rich layers, film labels are mostly roll-to-roll printing, which requires volatile drying ink. Offset printing can print thicker plastic materials and is suitable for high-volume printing. So what are the temperature requirements for self-adhesive labels?

1. What effect does temperature have on self-adhesive labels:

1. The storage environment temperature of the label should not be too low. Self-adhesive sticker materials placed outdoors or in cold environments are very likely to cause frostbite, especially in the glue area. Without proper recovery, the stickiness and production processability of self-adhesive labels can be lost or lost as a result.

2. Label preset processing This is very important in cold places. If the ambient temperature of the label itself fails to meet the requirements considering the logistics, transportation and storage conditions, resulting in a low ambient temperature of the label itself, or even frostbite, although the ambient temperature of the label meets the requirements, the label status cannot be restored in a timely manner. The stickiness of the self-adhesive label will be affected as well as the production and processing performance. Therefore, under the above-mentioned circumstances, the label manufacturer should preset the label material in the label environment for 24 hours before the actual production, processing or labeling operation, so that the ambient temperature of the label material itself will rise to a certain extent. In turn, viscosity and production processability can be restored.

2. Types of self-adhesive labels:

1. BOPP labels are widely used in transparent daily chemical products, and the appearance is transparent film

2. PET and PVC labels PET is a polymer polymerized by free radical polymerization under the action of light and heat. PET has high heat resistance and is not recyclable, while PVC has poor heat resistance and is recyclable.

3. Water-soluble paper label glue and facial paper are extracted from starch and quickly dissolve in water. It is a high-end environmental protection label

4. The removable label is a label with removable glue. 5. The sub-silver label surface paper is sub-silver material, and the glue includes oil glue and water glue.

3. Why do self-adhesive labels occupy an important position in the printing industry:

1. As an important part of the packaging and printing industry, the self-adhesive sticker label is very popular among users because of its convenient use and various forms. With the continuous improvement of the living standard of self-adhesive printing and the increasingly fierce competition in the market.

2. In addition to high-quality features, self-adhesive sticker label products must also have high-quality and inexpensive appearance packaging. The publicity of many domestic imported TV, magazines, Internet and other media has made people pursue the appearance of self-adhesive sticker labels. It is getting higher and higher, so self-adhesive label manufacturers have become an indispensable and important part in the packaging industry.

3. In addition, the demand and quality requirements of self-adhesive labels have regional characteristics, and the production requirements of different local consumption levels of self-adhesive label manufacturers are also different. Self-adhesive printing, self-adhesive printing is economical The higher the level, the higher the demand and quality requirements for self-adhesive labels. Relatively speaking, this kind of self-adhesive printing production method occupies a major position in the domestic self-adhesive label printing production. It uses letterpress printing for self-adhesive labels, the printing plate is photosensitive resin letterpress, and uses water-based suitable for flexographic printing. Ink or uv ink, change the properties of the ink to adapt to the change of the substrate.
