Testing labs in Leiden

AD Procerta™ is an accredited label testing and qualification laboratory operated by Avery Dennison Materials Europe BV, located at the Leiden Bio Science Park in Oegstgeest, Netherlands (Willem Einthovenstraat 11, 2342 BH). Launched in 2022, the laboratory was established to address a critical gap in the label supply chain: the need for rigorous, application-specific testing that goes beyond generic industry standards. Backed by over 80 years of Avery Dennison expertise in pressure-sensitive materials, AD Procerta offers brands, converters, and formulators a highly streamlined path to label qualification, helping them reduce risk, accelerate time-to-market, and ensure their labeling materials will perform reliably in demanding real-world environments. The laboratory's testing scope encompasses the full performance envelope of pressure-sensitive label materials and constructions. Core service areas include adhesion performance evaluation (peel adhesion at various angles and temperatures, loop tack testing for immediate adhesive contact), high-speed dispensing simulation to verify label integrity on automated filling and labeling lines, print durability assessment covering resistance to abrasion and smearing, and chemical resistance testing to confirm label survival when exposed to solvents, cleaning agents, lubricants, or pharmaceutical excipients. Environmental exposure and weathering simulation is a particular specialty, with capabilities to subject labels to humidity cycling, UV radiation, immersion, and extreme temperature ranges down to −80 °C to replicate the harshest storage, sterilization, or outdoor conditions. AD Procerta serves clients across the pharmaceutical, medical device, automotive, electronics, and premium food and beverage industries. In pharmaceuticals, the lab validates labels for prefilled syringes, vials, ampoules, and clinical trial packaging, where label failure can have direct patient-safety implications. For the automotive sector, testing protocols simulate under-hood exposure to oils, fuels, and wide thermal cycling on engine components and wiring harnesses. Premium drinks brands—including champagne and wine producers—rely on AD Procerta to verify that label adhesion, print quality, and moisture resistance hold up through chilling, condensation, and extended shelf storage. Chemical drum manufacturers and industrial packaging users also leverage the lab to confirm label legibility and adhesion through regulatory-mandated transport and storage scenarios. The facility employs over 100 instruments to simulate real-world application conditions. Testing platforms include universal testing machines for mechanical adhesion and peel measurements, environmental chambers with programmable temperature and humidity profiles, xenon arc and UV weathering chambers, high-speed label application rigs, analytical instruments for print and coating evaluation, and purpose-built chemical immersion rigs. Crucially, AD Procerta develops proprietary protocols tailored to clients' unique substrates and application conditions, supplementing existing FINAT standard tests (the European federation for self-adhesive label manufacturers) wherever those standards alone do not capture the specific demands of a given application. This customized methodology is a core differentiator: the laboratory does not simply run off-the-shelf tests but designs test suites in direct collaboration with clients to replicate their actual production, storage, and end-use environments. AD Procerta's accreditation to ISO/IEC 17025 (registration number L702, granted by the RvA — the Dutch Accreditation Council, Raad voor Accreditatie) provides internationally recognized assurance of the laboratory's technical competence and the validity of its test results. ISO/IEC 17025 is the globally accepted benchmark for testing and calibration laboratories, covering requirements for management systems, measurement traceability, uncertainty of measurement, method validation, and personnel competence. The RvA accreditation means that AD Procerta's test data carries cross-border recognition under ILAC (International Laboratory Accreditation Cooperation) mutual recognition arrangements, making results usable to support regulatory submissions, supplier qualification audits, and product launch dossiers across the EU and in many international markets. The laboratory's geographic positioning within Avery Dennison's European manufacturing and R&D campus in the Netherlands enables short lead times that independent third-party labs often cannot match, while also providing seamless access to the broader Avery Dennison group's materials science expertise and product development capabilities. When testing identifies a label performance shortfall, the AD Procerta team can draw on Avery Dennison's material formulation and converter network to propose and rapidly iterate on improved solutions—compressing the qualification cycle that would otherwise require multiple rounds of re-sourcing and re-testing across separate suppliers and labs. For brands and manufacturers navigating complex labeling compliance requirements—whether driven by European medicines regulations, automotive OEM specifications, UN transport regulations for dangerous goods, or premium-brand quality standards—AD Procerta offers a rigorous, credible, and efficient partner. The combination of accredited testing infrastructure, deep application knowledge in pressure-sensitive materials science, and collaborative engagement model makes AD Procerta a trusted resource for qualification projects that require more than commodity test results. Clients receive not only reliable data but also expert interpretation, helping procurement and quality teams make informed material-selection decisions with confidence.
