Compound Development

Compounds are specially formulated liquid plastisols that are applied to the interior of a metal closure to enable sealing onto a container and ensure barrier performance.

Crown's R&D facilities in Wantage, U.K. and outside Chicago, Illinois (U.S.), together with our Center of Excellence in Lancaster, Ohio (U.S), are responsible for the development of new compound technology and the improvement of existing formulations.

All three facilities are staffed by world-class experts in chemistry and microbiology and possess knowledge of global, industry-relevant safety regulations that develop new compound technology and aim to improve existing formulations.
