Adhensive of Adhensive Labels Roll

Surface material of adhesive labels roll is the substrate, every surface has its own physical and chemical characteristics, for different terminal products, it is not complicated, to choose suitable surface paper, but the choice of adhesive is not as easy as the choice of surface material.

Different adhesives are suitable for different adhesives and labeling requirements. For example, the glassware requires the label to be torn off within a certain period of time after affixing, the adhesive itself will not cause damage to the glassware itself and there are adhesive residues. The same is true for stationery products and furniture products, as well as for efficiency labels on air conditioners and refrigerators, which are used at homes. However, most of them do not need to be torn off after posting and they are permanently posted on the  objects.

There are several main factors to consider when choosing adhesives

1. The materials of the posted objects: paper, plastic, metal, glass, china and so on.( different surface tension).

2. The shapes of the pasted objects: plane, hook face, arc sizes of hook face, caliber sizes of bottles and so on.

3.  The surface condition of the pasted objects: flatness, precision, roughness, cleanliness and  humidity.

4. Labeling ways: manual,  self-labeling, labeling speed and labeling pressure.

5. Labeling environment: temperature and humidity during labeling,  the cleanliness of the labeling site and whether there is dust in the space.

6. Storage environment: the storage humidity and ultraviolet light of adhesive labels roll material after labeling and before labeling.

In the labeling process, it is easy for labeling personnel to ignore the chemical viscosity of adhesive labels roll material and despise the mechanical viscosity. In fact, the use of suitable adhesives can make labeling safer under certain pressure. The special case is that the adhesive of hot melt adhesive series is not suitable for pasting on PVC material, because the chemical composition of the adhesive itself and the plasticizer composition of PVC itself have chemical reaction and produce the phenomenon of glue penetration and then it damage the pasted surface.
