Before using different types of self-adhesive labels, it is important to test the type of adhesive. It is important to see if this adhesive is a self-adhesive, heat-sealing adhesive, or glued paper. Some adhesives react chemically with certain substances. For example, self-adhesive labels used as signage can contaminate certain special fabrics under certain conditions. Some labels that require short-term stickiness will produce long-lasting stickiness under exposure conditions. On the other hand, some labels that require long-lasting adhesion will lose adhesion on some surfaces. When using self-adhesive labels and other labels on the surface of recycled paper, problems often occur. There are many different papers in the process of recycling, and some papers will be contaminated with silicon or wax coatings, so that the mixed processing will pollute the final recycled products. When using labels on the surface of these contaminated recycled paper, the adhesive tends to be useless. Note: The role of the silicone coating in the sticker is to ensure that the sticker can be easily removed from the liner. Low temperatures can also cause problems. Low temperature reduces the speed of bonding. Before the adhesive sticks to the surface, the label may have peeled off the surface. If the label is stored improperly-large environmental temperature difference, large fluctuations in humidity, or improper stacking-the label will lose its stickiness soon after use. One of the most important factors for the effective use of stickers is to properly peel off the stickers from the surface of the backing paper. Many people mistakenly pull and pull from the left or right corner of the label, which will weaken the adhesiveness of the adhesive part of the contact, and will also destroy the "surface fibers" in the material, causing the label to curl. The correct method for tearing the self-adhesive label from the surface of the liner is to keep the label as straight as possible, and peel the liner from the center of the top or bottom to ensure that the label adheres well to the surface of the object.
