Self-Adhesive Material

The use of labels in the various technical industries places extremely high demands on their stability and durability. They are becoming more and more of a functional element in the production sequence and therefore an important component with high quality requirements. Due to its versatility, the film label is becoming increasingly established in these areas and can have considerable advantages over paper because of its specific properties. Film has a higher-quality appearance, does not wear as quickly as paper, and provides significantly more stability and resistance to the effects of the environment. It is also recyclable and can be used for transparent labels to achieve a "no label look". Whereas controversial PVC was the preferred packaging and labeling material in the 1980™s, modern industry now relies on ecologically safer materials such as polyolefin film (PE/PP) and polyester film (PET), which are the choice for a wide variety of applications. The differences between the different film types vary depending on the chemical composition.


In order to reach the required level of adhesive on the substrate, selecting the right adhesive is of pivotal importance. Listed here are some significant determining factors:

Rough Surfaces

Special adhesives that bond to the surface. For very rough surfaces, adhesives with increased application weight are required. Due to the increased amount of glue, the adhesive is able to flow into the recesses of the surface, resulting in greater adhesion. We offer special solutions that cannot be reached with any standard adhesive material.

Curved surfaces

Despite high stiffness of the film material, bonding of the label is made possible. Initially, this will be reached by adhesives with high initial adhesion, however, the final adhesion must also be achieved. Another alternative is the use of overlapping labels.

Low Energy Surfaces

Some plastic surfaces have low surface tension or contain a layer of release agents. As a result, they virtually reject many types of adhesives. Special adhesives with modified resins offer numerous advantages and adhere to the surface to achieve a increased bond strength.


Temperature Effects

We distinguish between:
a) high temperatures: special adhesives do not show any visual changes at high temperatures, for instance in the production of printed circuit boards.


b) low temperatures: for deep-freeze application, there are selected adhesives showing good adhesive forces even under cold conditions.



Lightly Soiled Surface

In general, any surface should be free of dirt and moisture before applying - selected adhesives can absorb certain amounts of dirt/moisture without losing adhesive strength.
