Coatings might be the least trendy topic in the packaging world, but they're pivotal to the food and beverage industry. It's the unseen layer that no one thinks about, but without it, many packaging materials wouldn't be viable for housing our favourite consumables.

For these reasons, and with most commercially available coatings featuring plastic, next-generation alternatives are beginning to emerge. But there's still much work to be done.
