Evonik Launches DEGALAN VP P 34, a New Heat-Sealing Binder

摘要

Methacrylate binders from Evonik, marketed as DEGALAN, are designed to offer multiple possibilities for the formulation of heat-sealing lacquers. They are used in the sealing of yogurt containers and pharmaceutical blister packaging. The requirements placed on packaging coatings are high because packaging substrates can vary widely, the company said. Yogurt lids, for example, consist of aluminum or plastic; these in turn must be sealed to a variety of container materials such as polypropylene (PP), polystyrene (PS) and polyethylene terephthalate (PET).
