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.
