The rectangular and lightweight nature of the carton means that it is space and transport efficient, thereby reducing fuel consumption and CO2 emissions.
A truck loaded with filled cartons transports approximately 95% product and only 5% packaging, fuel consumption and associated emissions, are therefore much reduced compared with the transportation of more space-consuming products.
Similarly, before filling, cartons are highly space efficient, as they travel flat-pack.
