NPI is a market leader in pond liners. At our production location in Tzummarum, we process millions of square metres of pond liner annually. The pond liners are supplied as standard rolls, in package form or as customised project-based solutions. Even three-dimensional forms are no problem whatsoever. Our pond liner range includes high-quality films such as 4everflex®, PVC and EPDM.
NPI continuously invests in the latest technology to achieve optimum quality and efficiency. We use high-quality welding equipment, which allows us to use a variety of welding techniques. Automated wrapping machines and palletisers ensure efficient packaging and processing.
Our team represents more than 60 years of experience and craftsmanship in welding and manufacturing various types of film. Our team is diverse and each member has his or her own specialism.
We are also KIWA and ISO 9001 certified, which means we comply with strict international safety and quality standards. Our quality control system, combined with goods entry and exit protocols, constant testing and controls guarantees a high-quality final product.

Tailor made solutions
We can produce tailor made items of up to around 5,000 m² in a single piece in our production hall. Even larger bespoke items are possible. We can weld pieces together on location to create films with unlimited dimensions. Our expert advisers would be happy to discuss the design and implementation with you.
In recent years, NPI has handled various pond liner projects at home and abroad. For example, we have realised unique water features for (leisure) parks, swimming ponds, artificial lakes, basins, ornamental ponds and firefighting ponds.
