How to judge the quality of self-adhesive labels? 【Adhesive stickers】

Before choosing a self-adhesive label, it is important to test the type of self-adhesive to distinguish whether the adhesive belongs to ordinary self-adhesive, heat-sealing adhesive or adhesive tape .

After determining the type of label glue, you can choose the corresponding label according to your own situation. Because some adhesives react chemically with certain substances. For example, self-adhesive labels used as signage can stain certain special fabrics under certain conditions. Some labels that require a short tack will develop a persistent tack under exposure conditions. On the other hand, some labels that require long-lasting tack will lose tack on certain surfaces.

A problem often arises when using labels such as self-adhesive labels on recycled paper surfaces. There are many different papers in the recycling process, and some papers can be contaminated with silicon or wax coatings, so mixed processing will contaminate the product after recycling. Adhesives tend to lose their effectiveness when labels are applied to these contaminated recycled paper surfaces. NOTE: The purpose of the silicone coating in the sticker is to ensure that the sticker comes off easily from the liner. Too low a temperature can also cause problems. Low temperatures will slow down the bonding speed and the label may peel off the surface before the adhesive sticks to the surface. If stored in damp conditions, or improperly stacked - labels will lose their tack quickly after use.

One of the most important factors in the correct use of self-adhesive labels is to correctly peel the self-adhesive from the surface of the backing paper and use the method of tearing off the middle. It breaks the stickiness of the sticker and also breaks the "surface fibers" in the material, causing the label to curl. Before removing the label, try to keep the label as straight as possible. Peel the backing paper from the center of the top or bottom end to ensure that the label sticks well to the surface of the object.
