Adhesive, in particular, can come in the form of animal-based gelatine. Often this especially affects the labelling of the goods. “Glutin” (bone glue from animal waste products) or casein are therefore unsuitable as adhesive components for vegan packaging. The rule here is that all materials like dyes, lacquers, adhesives and additives must be guaranteed free of animal compounds. Vegan labels can be produced using synthetic adhesives; but these must also cause no issues for recycling which would drive the price of the products upwards.
Overall, it can be said that the topic of vegan packaging is being taken seriously by many producers but it has still not found a wide customerbase as yet. However, this may change in the coming years as the topic seems to be in fashion, especially among the target group of Generation Y.
