How to test the adhesive label stickiness

Before using different types of adhesive labels, it is very important to test the type of adhesive. Look at this kind of adhesive is a self-adhesive, heat-sealing adhesive or glued paper. Some adhesives react chemically with certain substances. For example, stickers used as labels can contaminate certain special fabrics under certain conditions. Some labels that require short-lasting tack will produce long-lasting tack under exposure conditions. On the other hand, some labels that require long-lasting tack will lose their stickiness on some surfaces.

Problems often occur when using adhesive labels and other labels on the surface of recycled paper. In the process of recycling, there are many different kinds of paper, some of which are contaminated with a coating of silicon or wax, so that the mixing process contaminates the final recycled product. When using labels on the surfaces of these contaminated recycled papers, the adhesive tends to lose its effect. Note: The role of the silicone coating in the sticker is to ensure that the sticker is easily removed from the liner.

Low temperatures can also cause problems. The low temperature reduces the speed of the bond and the label may have peeled off the surface before the adhesive sticks to the surface. If the label is stored improperly - large temperature differences in the environment, humidity fluctuations, or improper stacking - the label will lose its viscosity soon after use.

One of the most important factors for the effective use of adhesive labels is the correct peeling of the sticker from the surface of the liner.

Many people mistakenly uncover and pull down from the left or right corner of the label. This weakens the tackiness of the adhesive on the contact area, and it also destroys the “surface fibers” in the material, causing the label to curl.

The correct way to peel off the sticker from the surface of the liner is to keep the label straight 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.
