The Laboratory for Testing of Materials and Unit Packaging conducts comprehensive testing of unit packaging and packaging materials made of plastics, paper, cardboard and other materials. The Laboratory carries out research activities related to innovative packaging materials, product–packaging interactions, effectiveness of product protection, and development of new packaging materials and packaging solutions.

The laboratory participates in international and national projects as well as contracts concluded with enterprises.
The laboratory operates in the field of adapting testing methods and evaluating packaging materials intended for contact with food in accordance with EU requirements. It supports the implementation of new packaging materials, packaging and packaging systems into production, and also conducts training courses, seminars and conferences related to packaging materials, packaging and packaging technologies.

The laboratory is accredited by the Polish Centre for Accreditation in accordance with PN-EN ISO/IEC 17025:2018-02 for chemical and mechanical testing of plastic products and packaging materials, physical property testing of paper, cardboard, plastics and packaging materials, and sensory testing of paper, cardboard, plastics and packaging materials.
