Sealio is a patented carton-based packaging system, including both material and machinery, presenting strong benefits also when it comes to the environment and logistics. It is considerably lighter and has less carbon footprint than comparable gas tight packaging alternatives such as tin cans and full plastic containers. The can is formed directly in the packaging line with all components delivered flat to the food producer. External and internal transports as well as the warehousing space is thereby reduced substantially. Designed for Infant Milk Formula and other sensitive food products.
