protaral® – Research & Development

During recent years the Research & Development Office of Weilburger Group has created innovative solutions adopted world-wide.
protaral® is a continuously developing product: tests and research are carried out every day on new applications which allow the Group to honour their mission, namely: to offer safe, reliable and innovative solutions with full respect for the environment and people.

protaral® Hydro, a water-based interior coating, was developed in keeping with the Group’s mission to offer safe, reliable and innovative solutions whilst respecting fully the environment and people.

Thanks to ongoing research on product improvement, emissions of volatile organic compounds from protaral® coatings are well below the allowable limits laid down by European directives, thus further proving the company’s commitment to the environment and people.

The aim of an ever growing number of companies is to reduce the environmental impact of its products. Aluminium is a 100% recyclable material. To choose aluminium packaging is to make a choice that favours the environment.

Heat sealing laquers for internal protection for lids

Continuous investment in research and development has recently allowed Weilburger to develop a line of water-based interior coatings for aluminium packaging, namely protaral® Hydro, which from its initial applications has passed the various resistance, flexibility and durability tests with outstanding results.
Currently our research staff are working on a new product totally free of bisphenol with promising results.
