Innovative coloring of WS NPKs

We developed an innovative coloring concept. The result is an intense and consistent coloring of the products as well as the solutions. You can choose from a wide range of colors which allows you to stand out in the market. Our approach: Pick your own color!

Packaging available at TTD

We can pack an extended range of different types of bags, from 1 up to 25 kg. Our facility can keep up with a capacity of 1200 bags per hour. Special attention is paid to the strength of the bag and the seal for which our quality controller has implemented a bag drop test.

To enable you to add your identity and product specific information on the Van Iperen bags, we implemented a dedicated printing technology without using labels. Tracking and tracing is guaranteed by a  barcode printed on the bag. The printing is done while packing the product, which increases the flexibility.

Each bag is weighted and cleaned after packing before palletization and shipment.
