Description

Coextruded film performance depends on layer architecture decisions made long before production starts. This advanced training focuses on designing multilayer structures that consistently meet OTR, WVTR, mechanical integrity, and regulatory requirements under real manufacturing conditions. Participants will learn how material selection and layer sequencing influence barrier stability, interlayer adhesion, curl, gauge variation, and long-term performance drift. Training examines practical design strategies for high-barrier structures using EVOH, polyamide, polyethylene, polypropylene, and functional tie layers, with emphasis on how processing conditions and moisture exposure affect barrier reliability. Special attention is given to common production failures such as delamination, neck-in, haze, and thickness instability, and how these issues originate from structural or material mismatches rather than equipment settings. Compliance considerations are integrated throughout, including migration risk, food contact requirements, and PPWR-driven design constraints for recyclable packaging. The training provides decision frameworks to balance barrier performance, recyclability, cost, and process stability, enabling formulators and process engineers to design coextruded films that meet both performance targets and regulatory expectations without repeated redesign cycles.

Why you should not miss the training?

Why is this training essential? The value lies in these five specific outcomes;

1. Crack the EVOH humidity code: Learn practical methods to protect your moisture-sensitive barrier layer from performance loss.

2. Prevent costly delamination in production: Understand the precise material and process settings that guarantee perfect layer adhesion.

3. Right-size your material costs: Learn to calculate the minimal barrier layer thickness needed to meet your specific shelf-life target.

4. Avoid over-engineering your packaging: Gain the knowledge to build a lean, effective structure without unnecessary or redundant layers.

5. Solve the recycle ready barrier puzzle: Get ahead of regulations with insights into developing high-performance mono-material barrier films.

Who should attend this training?

This is one of those technical trainings which is highly recommended for polymer and plastic industry professionals including: 

        - R&D chemist, formulators, chemical engineers
        - Product developers, scientists, technicians, lab managers
        - Specialist and professionals from coatings, polymers and related industries
