What are the characteristics of the stickiness test method for self-adhesive labels?

Self-adhesive stickers are also called self-adhesive stickers, instant stickers, instant stickers, pressure-sensitive paper, etc., which are made of paper, film or special materials, with adhesive on the back, and silicon-coated backing paper as a protective paper. A composite material, and after printing, die-cutting and other processing, it becomes a finished label.
1. Before using different types of self-adhesive labels, it is very important to test the type of adhesive to see whether the adhesive belongs to self-adhesive Yijiaqi glue, heat-sealing glue or glue-coated water paper. Some adhesives will interact with specific substances A chemical reaction occurred.
1. The self-adhesive labels used as signs will contaminate some special fabrics under certain conditions, and some labels that require short-term stickiness will produce long-lasting stickiness under exposure conditions, while on the other hand, some need to have long-lasting stickiness. Adhesive labels lose their stickiness on certain surfaces.
2. Too low temperature of self-adhesive will also cause problems. Low temperature reduces the speed of bonding. Before the adhesive sticks to the surface, the label may have peeled off from the surface. If the label is not stored properly - the ambient temperature difference is large and the humidity fluctuates Large, or improperly stacked—labels lose their stickiness quickly after use.
Second, one of the most important factors for the effective use of self-adhesive labels is to correctly peel off the self-adhesive from the surface of the backing paper.
Many people mistakenly print the label and pull it off from the left or right corner of the label. This will weaken the adhesiveness of the contact part of the self-adhesive, and it will also damage the "surface fiber" in the material, causing the label to curl.
The correct way to tear off the self-adhesive sticker from the surface of the backing paper is: try to keep the label as straight as possible, and peel off the backing paper from the center of the top or bottom to ensure that the label is well bonded to the surface of the object.
Compared with traditional labels, self-adhesive labels have the advantages of self-adhesive labels without glue, paste, water, no pollution, and saving labeling time. They have a wide range of applications, are convenient and fast, and self-adhesive is a kind of material. Also known as self-adhesive label material, it is a composite material with paper, film or other special materials as the fabric, adhesive on the back, and silicon-coated protective paper as the backing paper. It becomes a finished label after printing, die-cutting and other processing.
