Check the adhesiveness of the sticker. The correct way to tear the sticker from the surface of the backing paper is to keep the label as straight as possible, and tear it from the center of the top or bottom of the backing paper to ensure that the sticker fits well on the surface of the object.
Some adhesives react chemically with certain substances. For example, under certain conditions, a self-adhesive label used as an identification can contaminate certain fabrics when printed. Some labels require short-term tack, which will produce long-lasting tack under exposure conditions. However, those labels that require long-lasting adhesiveness lose their adhesiveness on some surfaces.
The printing of self-adhesive labels and other labels often have problems when used on the surface of recycled paper. There are many different papers in the recycling process, some of which will be contaminated by the coating of silicon or wax, so the mixed treatment will contaminate the final recycled product. When labels are used to mark the surface of these contaminated recycled paper, the adhesive is prone to failure. Note: The function of the silicone coating on the self-adhesive label is to ensure that the self-adhesive is easily separated from the backing paper.
Too low temperature can also cause problems. Low temperature will slow down the bonding speed, and the
paper sticker will fall off the surface before the adhesive sticks to the surface. If the
paper sticker is stored improperly, that is, the environmental temperature difference is large, the humidity fluctuates greatly, or the stack is improperly, the label will lose its stickiness soon after use.
