Quality Standards
For us, quality is not just about the product itself, but the entire experience the client gains from working with us. That’s why we support our clients and offer expert consulting on every matter, ensuring both visual appeal and practical usability of the packaging.
We employ creative engineers whose skills, knowledge, and experience are reflected in every project. Modern technological solutions form the foundation of our original designs, setting new market standards in the packaging production industry.
At Prost-Key, quality is a priority from the selection of trusted raw materials to the production of the final product. We ensure quality by conducting tests at every stage of the production process. In our laboratory, we examine paper, cardboard, and the finished product.

Our efforts have been recognized with the Quality Management System Certificate PN-EN ISO 9001:2015-10. We also meet the requirements of standard PN-EN ISO 22000:2018-08. In our daily operations, we emphasize environmentally friendly solutions and eco-conscious practices: we produce packaging using materials with FSC® Certification, ensuring that the raw materials come from FSC®-certified forests, meaning they are sourced within the framework of responsible forest management. We follow the standards of the Forest Stewardship Council® not only during material procurement, but throughout the entire production process and supply chain.
