How to check the stickiness of self-adhesive labels | sticky labelNov 05, 2021
When using self-adhesive labels and other labels on the surface of recycled paper, problems often arise. There are many different papers in the recycling process, and some papers will be contaminated by the coating of silicon or wax, so the mixed process will contaminate the final recycled product. When labels are used on the surface of these contaminated recycled paper, the adhesive often loses its effect. Note: The role of the silicone coating in the self-adhesive label is to ensure that the self-adhesive is easily detached from the backing paper.
Too low temperature can also cause problems. The low temperature reduces the speed of bonding, and the label may have peeled off the surface before the adhesive sticks to the surface. If the label is stored improperly-with large environmental temperature differences, large humidity fluctuations, or improperly stacked-the label will soon lose its stickiness after use.
One of the most important factors in the effective use of self-adhesive labels is to properly peel the self-adhesive from the surface of the backing paper.
Many people mistakenly lift off the label from the left or right corner, which will weaken the adhesiveness of the contact part, and will also destroy the "surface fiber" in the material and cause the label to curl.
The correct way to tear the self-adhesive label from the surface of the backing paper is to keep the label as straight as possible. Peel 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.
