RIWISA AG

Company profile - History

RIWISA AG was founded on 11th March 1946 by Martin Richner, Adolf Wirth and Joseph Sax as one of the first plastics’ processing firms in Switzerland. Initially the firm made a name for itself in the processing of buttons and toilet seats made from duroplastics and later in the manufacture of thermoplastics. From 1955 RIWISA AG produced polyaethylene, polyamide and multi-layer films as well as disposable packaging from 1957. In 1998 the production of medicinal items started under clean-room conditions.

The pioneer spirit has been a feature of the family firm from the beginning. Since then RIWISA AG has continuously invested into the latest technologies and infrastructure. Inseparably linked with the firm’s philosophy is the ambition also to succeed in international competition.

Today, with more than 300 employees, RIWISA AG is numbered among the leading European manufacturers in the plastics’ processing field. Today the second-generation brothers, Gerold and Peter Richner, are responsible for managing the firm. The departments are divided into the three main areas.
