        abstract = {This technical report provides a comprehensive analysis of adhesive systems and hardener applications in lamination processes, focusing on their chemistry, performance, and sustainability implications. It examines major adhesive families—water-based, solvent-based, solventless polyurethane (PU), hot-melt, UV/EB-curable, pressure-sensitive, and epoxy—highlighting their curing mechanisms, ingredient composition, and industrial applications. Special emphasis is placed on pot life management, a critical parameter in two-component systems that influences process stability and bond integrity. The report compares solvent-based and solventless technologies in terms of environmental impact, operational efficiency, and compliance with food-contact regulations (e.g., 21 CFR standards). Chemical reaction pathways for PU and epoxy adhesives are detailed to explain property development and performance under thermal and mechanical stress. Additionally, the report addresses ESG compliance strategies, including VOC reduction, adoption of bio-based raw materials, and recyclable mono-material laminates, aligning with global sustainability frameworks such as ISO 14001 and the EU Green Deal. Visual aids—including diagrams, charts, and an infographic—summarize adhesive types, pot life behaviour, performance attributes, and application sectors. A troubleshooting guide and root cause vs. solution chart are provided to assist converters in resolving common lamination defects. This integrated approach equips stakeholders with actionable insights for optimizing adhesive selection, improving process reliability, and advancing sustainability in flexible packaging and technical laminates.},
