High barrier coatings act as hurdles to oxygen, moisture/water vapor, CO2 and volatile organics in order to prevent the penetration or loss of the specific gas. The term “barrier” indicates the function of the film to seal contents from outside factors that would cause quality degradation and to preserve inside original conditions. Gas barrier coatings would slow down or block the permeation through the film of gases like oxygen, water vapor, carbon dioxide and other gases that have a major impact on the quality of products. Barrier films used in the food industry ensure aroma protection, longer shelf life and less food waste along the value chain. Transparent multi-gas barrier solution is provided by the synergistic effects of water-based coating technology and AlOx deposition. Unlike typical oxygen barrier coatings which fall under high humidity conditions, the innovative approach based on the integration in lacquers of crosslinkers and beads technology ensures greater stability of oxygen barrier coatings under high RH conditions (>80%) typical of wet applications.
