Industrial applications: Using Plasmatreat’s Openair® plasma treatment to create optimum conditions for adhesive bonding in the packaging industry

High production rates require stable processes

Regardless of whether the objective is to label a jam jar, to print on a glass bottle or to seal milk or juice packs a key factor in the packaging industry is the ability to process the various materials reliably and at low cost.

Pretreatment for gluing safety labels
Openair® plasma pretreatment allows the use of universal adhesives

Pretreatment with Plasmatreat’s Openair® plasma makes it possible to process different materials and coatings, even those that are very thin, as is the case, for example, in the production of composite packaging units. Cardboard packaging units are processed at very high speed. If in doing so an adhesive bond is needed, recesses in the area of the bonding surfaces have to be carefully taken into account, especially in the case of high-gloss surfaces coated with plastic. Otherwise the plastics employed will not adhere. By using Plasmatreat’s Openair® plasma technology this problem is eliminated. High-gloss gluing points can be directly and selectively pre-treated in-line so that reliable bonding is ensured.

Plasmatreat’s plasma pre-treatment technology allows for simple processes

In the labeling of glass bottles Plasmatreat’s Openair® plasma is employed for pre-treating the glass. This allows the use of a universal and above all low-cost water-based labeling adhesive.

Metal lids on jam jars are molded into shape using a lubricant. Some of this lubricant remains adhering to the painted metal surface. In order to avoid using an additional adhesive and to allow use of a universal adhesive for all products Plasmatreat’s Openair® plasma is employed to pre-treat the metal surface.
