Testing labs in Grenoble Cedex 09

Centre Technique du Papier (CTP) is a French pulp and paper research and technical center located in Grenoble, serving the European paper, cardboard, printing and packaging industries. Founded as a public utility establishment with approximately 120 technical and scientific staff, CTP provides independent laboratory testing, consultancy, training and collaborative research services to pulp, paper, board, and packaging manufacturers. The organization operates headquarters in Grenoble (341 rue de la Papeterie, 38610 Gières) and a secondary location in Douai (59 rue Jean Perrin, ZI de Dorignies, 59500 Douai), with a delivery hub in Saint Martin d'Hères. CTP's microbiological analysis laboratory is COFRAC-accredited (scope 1-0552) under ISO 17025 and performs food contact and hygiene testing in compliance with AFNOR, ISO, and CEN standards. The laboratory detects and counts indicator microorganisms, food-borne pathogens (such as Listeria, Salmonella, E. coli), and spoilage organisms including yeasts and moulds in paper and board raw materials, finished products, and food contact packaging. Testing includes assessment of antimicrobial constituent transfer, fungal resistance, residual biological contamination, and microbiological quality assurance. The facility includes Class 2 safety cabinets, autoclaves, incubators, microscopes and maintained bacterial and fungal culture collections. CTP offers comprehensive laboratory testing across multiple analytical disciplines. Physical and mechanical testing evaluates barrier performance, recyclability, moisture resistance, and processing characteristics of paper and board products used in food and beverage packaging. Chemical analysis includes composition determination, contaminant detection, and compliance assessment against food contact regulations. Fiber characterization and pulp analysis determine fiber morphology, length distribution, fibrillation, and mechanical properties. Material performance testing assesses laminates, coatings, adhesion, water resistance and other end-use properties of paper-based materials. The center serves the paper and board packaging industry with specialized expertise in food contact compliance, where regulatory adherence is critical. CTP provides consultancy on regulatory requirements including EU Regulation 1935/2004 (food contact materials), French DGCCRF regulations, and BfR recommendations. The organization maintains an active research portfolio in sustainable packaging innovation, including development of bio-based materials, decarbonation initiatives, recyclability optimization, and water management in manufacturing processes. Food contact applications are a major focus, with training programs (such as QHS-01 Food Contact Regulation) and proficiency testing for packaged food safety. CTP maintains COFRAC accreditation through ISO 17025 for its analysis and testing laboratory services, ensuring technical competence and independent operation. The center is affiliated with Grenoble INP-Pagora (a leading pulp and paper engineering school) and participates in collaborative research through multi-year partnerships, such as the Citeo partnership (2022–2028) focused on paper-carton innovation and industrial scaling. Access to testing services is available via customer extranet portal, allowing clients to request quotes and track testing progress. Industry positioning centers on pulp, paper and board manufacturers seeking independent testing to meet regulatory requirements, optimize material performance, or validate process improvements. The organization's dual role as both testing laboratory and research center provides clients with access to cutting-edge methods, expert interpretation of results, and collaborative problem-solving for complex material challenges in food packaging, barrier systems, sustainability and industrial processing.
