Toray Industries (Japan): Plasma-grafted quaternary ammonium salts on PET substrates achieve 99.9% 24-hour antimicrobial efficacy with <2% haze.
Amcor China: 2024 water-based acrylic coating line reduces energy use by 62% and achieves zero VOC emissions.

AI Process Optimization: Bobst Group’s AI-controlled coating system reduces material waste by 23% with ±0.1g/m² precision.
Closed-loop Recycling: Terracycle-Pfizer’s network achieves 98.5% multilayer film separation purity (Q1 2024 data).

4. Process Selection Framework

4.1 Four-Dimensional Evaluation Model

SMEs prioritize solvent-free lamination (equipment cost <$500k, ROI <2 years).
High-value products (e.g., oncology drugs) adopt plasma + water-based hybrid processes.
