Dutch quality

Your reliable partner in packaging, filling service and assembling

Thanks to a very experienced team, specialist equipment, and strict procedures, we always deliver an end product that meets the highest quality requirements.

Each step in the production process is well checked and documented. In addition, we take at least six samples from each series for quality control purposes. These are retained for three years.

Consistency in high quality does not only characterise the end products. We also set the bar high when it comes to production and dealing with people and the environment.

Wherever possible we use sustainable, biodegradable materials. We endeavour to minimise energy consumption and waste flows. And we offer our team a pleasant and safe environment in which they can enjoy their work!

Our team

Filling Service

Our filling department has a wide range of high-quality, multifunctional automatic and semiautomatic filling lines that are capable of processing small and large orders with variations in filling quantities, packaging and labelling. This allows us to fill a wide variety of cosmetic, medical, and dental products on a daily basis.


We offer high-quality, in-stock packaging options with durable, functional materials like PP, HDPE, glass, amber, and aluminium containers in varying sizes. Our packaging includes additional features such as pumps, droppers, and spray nozzles, giving brands the flexibility to create an appealing and cohesive product while meeting practical needs.

One of our extended services is assembling. In combination with packaging and filling or separately, we can offer you the service to pack your products in your desired package and take care of logistics.
