The box format is rather exclusive and the cardboard supports the environmental trend (with FSC approved quality). Consumer like this concept as it is hygienic and convenient. Furthermore it is rather flexible with respect to content and can be filled as requested. We have two standards, the small with approximately 20g and the bigger one which can be filled with 24-36g. We have two different solutions for the sealing. Either we use a "tear" opening to avoid plastic, or we can use the more traditional PP foil.
