In 1892, more than 100 years ago, William Painter developed the crown cap. To begin with cork was used as seals and later replaced with PVC-compounds. Given the increasing environmental awareness in the 1980`s PVC-free compounds were developed and are nowadays used almost exclusively for crown caps.
Crown caps offer many functional advantages such as easy handling, high put on speed as well as sealing ability and quality assurance. They are a well recognised marketing tool to enhance the distinctiveness of a particular trade mark.
Set up in 1947 by Bartholomäus Rauh as a one-man business RRauh is today a medium-sized concern selling it`s quality closures for bottles worldwide – and seals them.
