Grosfillex is a family owned group of international standing. It has been located in Oyonnax, in France, at the heart of the Haut-Bugey region for 90 years.
The group developed its expertise in woodworking for 27 years before becoming the synthetic resin pioneer that it is today. Between the two World Wars the company was famous for its clothes pegs, egg cups, and tool handles. Grosfillex has kept its demanding approach to quality from this period, and its passion for working with materials to make consumers’ everyday lives easier.
The company is the flagship and emblematic pioneer of the Oyonnax Plastic Valley. Since 1954, when Raymond Grosfillex decided to invest in this new material to revolutionize the everyday lives of French consumers, it has pursued its pioneering spirit, developing many innovative products using synthetic resin.
