New anti-fog heat seal coatings are available for refrigeratable flexible packaging applications. Designed to improve package clarity and extend freshness for moisture-containing food products, the coatings reportedly allow converters and brand owners to address consumer preferences while streamlining processes and reducing overall costs.
Formulated to include both an anti-fog capability and heat seal functionality in one solution, the co-polyester coatings require one processing step. Available in both an extrudable grade (Vitel® 1922AF) and a solvent-based alternative, these coatings reportedly work with existing converting equipment and can accommodate various manufacturing needs.
