Evonik unveils heat-sealing binder Degalan for packaging

The requirements placed on packaging coatings are high because packaging substrates can vary widely. Yogurt lids, for example, consist of aluminium or plastic; these in turn must be sealed to a variety of container materials such as polypropylene (PP), polystyrene (PS) and polyethylene terephthalate (PET).

The new product, Degalan VP P 34, reduces the complexity of coating formulation enormously because only a single binder is used and only one solvent is therefore necessary. The reason is that DEGALAN VP P 34 is a bead polymer that is easily soluble in ethyl acetate, a commonly used, highly volatile solvent for heat-sealing lacquer formulations, Evonik said in a statement.

Degalan VP P 34 based formulations can be applied directly on the aluminium foil so that primers or formulations with a PVC-based adhesion promoter, which are still necessary today, can be dispensed with.

Evonik is active in over 100 countries around the world. In fiscal 2013 more than 33,500 employees generated sales of around €12.7 billion and an operating profit of about €2.0 billion. (GK)
