In 1957, the parents of the current owners, Walter and André de Winter, started the company in Wetteren, specialized in  cleaning and selecting  of hog casings.
Quality, service, flexibility and professionalism were, and still are, the keystones for the development and success of the company. In 1986, Walter and André took over the company. They modernized the production and the product range was extended with sheep and beef casings. Since 1992, the company grew significantly. A new plant was built in Lokeren, complying with the highest environmental and hygienic regulations. Currently, De Winter Natuurdarmen employs 150 staff, both in Belgium and abroad.
With an annual throughput  of five million pork intestines, De Winter processes more than half of all pork casings coming from Belgian slaughterhouses. Including the sheep and beef casings,  the company supplies more than one hundred million meters of natural casings per year to the sausage industry in Europe. Any company involved in the production of sausages in natural casings is a potential customer of De Winter Natuurdarmen. A major part of our business is with the Belgium sausage industry,  but we also have a firm customer base in countries like The Netherlands, Germany, France, Italy and Greece.
