Description

Flexible packaging performance depends heavily on the behavior of laminating adhesives under real processing and end-use conditions. This training focuses on formulation and process strategies for polyurethane laminating adhesives used in solvent-based and solvent-free systems, with emphasis on achieving reliable bond strength, cure stability, and resistance to demanding environments such as retort, hot-fill, and aggressive product contents. Rather than reviewing basic adhesive chemistry, the session examines how isocyanate index, polyol selection, residual monomer levels, and moisture exposure influence cure kinetics, CO₂ generation, and long-term laminate integrity. Participants will learn how formulation and mixing decisions affect pot life, coating window, and bond development, and why small deviations often lead to blocking, tunneling, or delayed delamination. The training also addresses migration risk, regulatory considerations for food contact structures, and the interaction between adhesive network density and chemical resistance. Special focus is given to troubleshooting real production failures and aligning adhesive design with high-speed lamination conditions. The objective is to enable formulators and technical teams to design laminating adhesive systems that deliver consistent performance, reduced scrap, and predictable behavior across diverse packaging structures.

Why you should not miss this training?

You're an expert, but the goalposts are moving. Here are five specific capabilities you will gain to lead the market and redefine what's possible with packaging adhesive chemistry;

1. Prevent Delamination Before It Appears in the Field: Understand how cure imbalance, moisture, and mix ratio errors lead to delayed bond failure.

2. Align Adhesive Cure with High-Speed Lamination Reality: Learn how formulation affects pot life, coating window, and production stability.

3. Design for Retort, Hot-Fill, and Aggressive Contents: Translate network structure into real chemical and thermal resistance performance.

4. Control Migration and Residual Monomer Risk Early: Avoid regulatory failures by managing cure completeness and extractable components.

5. Diagnose Production Defects at Their Root Cause: Identify formulation drivers behind blocking, tunneling, odor, and bond variability.
