An innovative solution for the food packaging sector
Consumer behavior is evolving: Increasing numbers of customers prefer to buy their meals “to go” and enjoy them at home or on the go instead of at a restaurant. The food service sector, especially the fast food industry, frequently relies on clamshell packaging, for example for burgers.
Simultaneously, environmental awareness is growing: consumers want plastic-free alternatives, and the demand for natural and sustainable packaging is constantly increasing.
Clamshell packaging made from natural fibers perfectly fulfills both of these consumer needs. It preserves the aroma and freshness of the food, offers optimal product protection and remains stable and tightly sealed – sustainable and functional.
