Overview
N.V. Primus Ouwelfabriek, trading as Primus Wafer Paper, is a Dutch manufacturer of edible wafer paper based in Oostzaan, Netherlands. Founded in 1916, the company describes itself as the global market leader in edible paper, a position it has held for over a century. Its core raw material is the potato — Dutch potatoes are the key source for its wafer paper — and the company states that its products are 100% biobased and produced in a circular way. Every year, roughly one million kilograms of wafer paper roll out of its Oostzaan production facility. Primus produces a range of wafer paper formats for industrial and consumer use. Its edible rolls are made using a unique roll-drying technology that yields very thin and flexible wafer paper, supplied on rolls ready for industrial use, with customizable widths from 200 mm to 1200 mm. Edible sheets are aimed at bringing brands to consumers' kitchen tables, while edible labels allow cakes and other foods to be decorated with photos, logos or pictures — a capability the company markets as 'edible branding'. A newer product line, Sweet Candy Paper, is an award-winning edible candy paper that melts on the tongue, is suitable for vegans and halal diets, and is positioned as irresistible and almost magical. The company also promotes wafer paper as a biodegradable packaging solution. Primus exports to more than 40 countries worldwide and operates a factory, laboratories, distribution centre and office in Oostzaan. It employs around 65 people, all based in Oostzaan, with additional warehouses and order-picking in other parts of the Netherlands and a packing partner in Poland. Its manufacturing department runs 24/7, while its processing department runs 16 hours a day, five days a week. The company's philosophy emphasizes entrepreneurship, teamwork, customer focus and resilience, and it sponsors local community activities such as a youth field hockey team. As a private company, Primus is not listed on a stock exchange. Its managing director, Wouter Smits, has publicly discussed the company's evolution into a world leader in edible paper with a bio-based process running around the clock. The company continues to pursue growth through edible branding and biodegradable packaging solutions under its 'Primus goes Prime' vision.
History
N.V. Primus Ouwelfabriek was founded in 1916 in the Netherlands, and has since built a century-long specialization in edible wafer paper. The company's own account states that it has been the global market leader in edible paper since 1916, a claim repeated across its official website. For much of its history it has been based in Oostzaan, where its factory, laboratories, distribution centre and office remain today. The company's core technology is roll-drying, which allows it to produce very thin and flexible wafer paper on rolls suitable for industrial use. This technology underpins its edible rolls product line, with customizable widths from 200 mm to 1200 mm. Over time, Primus expanded its product range from basic wafer paper into applications such as edible sheets, edible labels and, more recently, Sweet Candy Paper — an edible candy paper that melts on the tongue and is suitable for vegan and halal diets. In the last decade, Primus has evolved into a world leader in edible paper, exporting to more than 50 countries according to its managing director Wouter Smits, while its website more conservatively states export to over 40 countries. The company has emphasized a bio-based process that runs 24/7, and describes its production as 100% biobased and circular. Its annual output is approximately one million kilograms of wafer paper from the Oostzaan facility. Primus employs around 65 people, all based in Oostzaan, with additional warehouses and order-picking in other parts of the Netherlands and a packing partner in Poland. Its manufacturing department operates 24/7, while its processing department runs 16 hours a day, five days a week. The company's stated philosophy is that success is built on entrepreneurship and teamwork while being focused, customer driven and resilient. Under its 'Primus goes Prime' vision, it aims to strengthen its leadership through edible branding and biodegradable packaging solutions. The company also engages with its local community, for example by sponsoring a youth field hockey team.
