Our story

Top of mind.

Our story

It all started in 1936 when Jelte Kornelis first opened the company for the production of Bakelite. We’ve since grown into a leading supplier of caps and closures in the Netherlands and abroad with an exceptionally diverse client base. From major brands that keep our machines running day and night to specialised closures requiring custom solutions.

The right cap for the job.

Standard, sprinkle and fliptop: we produce the perfect caps and closures for every product - because a cap does much more than simply seal a product. A cap also serves as a signboard that your customer recognises your product by.

High quality sealing: temper evidence.

For a growing number of products, a seal is indispensable: temper evidence offers the consumer certainty and reliability. We can supply caps and closures together with a wide range of seal types and sizes. When selecting the seals, we select environmentally conscious materials wherever possible.
