Label Is the most widely used label, but its structure is not simple. A typical sticker from the five, comprising:
First level?? Surface material, or material, used for recording or printing graphic information.
Second?? Primer, or by adhesive coating, adhesive and surface material can be more closely integrated. Primer also have the role to prevent the infiltration of chemical reagents, or chemical reagents may come from the bottom three infiltration, dirty surface of the label. In addition, color paint can be used as the background transparent surface material.
Third tier?? Label adhesive. Tear off the label on the surface mount, the label affixed to the surface of an object before the adhesive to the surface materials and coated with silicon resin separated from the mount.
The fourth floor?? Silicone resin coating, used to ensure easy separation of labels and mount.
Fifth floor?? Mount to protect the label before use is not dirt, usually bleached, or primary color of Kraft paper (occasionally with a clean polyester materials) processed. Mount also support the role of ensuring the process of dealing with tags, labels will not bend or crimp. Label
Although widely used, is highly welcome, but it is not able to apply in any environment. For example, in frozen food packaging and other high-speed operation, more efficient use of heat seal labels, the economy.
The importance of viscous test Different types of tags in use prior to testing the type of adhesive is very important to see such adhesives are adhesive, heat sealing plastic or painted Glue Paper. Some adhesive material with a specific chemical reaction. For example, as a sign of self-adhesive labels will pollute under certain conditions some special fabrics. Some need a short sticky label under the conditions in the exposure will produce long-lasting adhesive. On the other hand, some need to have a lasting sticky surface of the label but will lose some stickiness. Viscous effects
the only way to ensure that select a particular surface to determine viscosity. Number of label material and adhesive manufacturers have testing capabilities. The surface in the use of recycled paper
stickers and other labels, there are always problems. Cycle during the course of processing a variety of different paper; some may be silicon or wax paper coating contamination, so the final mixing process to the regeneration of contaminated products. In these surfaces contaminated recycled paper label, adhesive tends to lose effect. Note: Self-adhesive labels in the silicone coating is to ensure the adhesive easily from the mount.
Temperature extremes can cause problems. Low temperature reduces the rate of bond, before the adhesive cement surface, the label may have been peeled off from the surface down. If the label stored properly?? Environment temperature difference and humidity fluctuation, or improper stacking?? Tag will soon lose their stickiness after use.
Effective use of stickers is one of the most important factor in correctly sticker peeled from the mount surface.
Many people are wrong, or right corner kick from the left corner to pull down tab, it reduced the access to some of the sticky adhesive, but also undermine the material in the "surface fiber," the label curl.
Ripped sticker from the surface mount is the proper way: Try to keep the label straight from the top or bottom of the center peel mount, you can ensure a good bond to the label surface.
