Type of adhesive label printing at the time of use, test type of adhesive is very critical and important, must see this kind of adhesive is not suitable for stickers, so with all of you to see the following.
Some adhesives react with certain substances. For example, a sticker used as a label can contaminate certain fabrics under certain conditions. Some labels that require a brief period of stickiness produce a lasting stickiness under exposure conditions. On the other hand, some labels that need to be permanently sticky lose their stickiness on some surfaces.
Problems often arise when the surface of recycled paper is printed with adhesive labels and other labels. In the process of recycling there are many different kinds of paper, some of which can be contaminated with a coating of silicon or wax, so that the mixing process pollutes the final recycled product. When the label is used on the surface of the contaminated recycled paper, the adhesive often loses its function. Note: the role of the silicone coating in the sticker is to ensure that the sticker is easily removed from the backing paper.


Too low temperatures can also cause problems. The low temperature reduces the rate of bonding, and the label may have peeled off the surface before the adhesive has cemented the surface. If the label is improperly stored -- the temperature difference is high, humidity fluctuates, or stacked incorrectly -- the label will quickly lose its stickiness after use.
One of the most important factors in the effective use of sticker printing is to properly peel the sticker off the surface of the backing paper.
Many people make the mistake of opening and pulling the label from the left or right corner of the label, which will weaken the stickiness of the contact part of the adhesive, and will also destroy the "surface fiber" in the material, causing the label to curl.
The correct way to remove the sticker from the backing paper surface is to keep the label as straight as possible, and to remove the liner from the top or bottom center to ensure that the label adheres well to the surface of the object.
Therefore, it is very important to check whether the stickiness of adhesive label printing is correct. I hope the above content can be helpful to you.
