• Good packaging protects the product from premature spoilage! Thanks to this protective function, packaging helps to minimise food waste.
• There isn't a type of packaging that can be said to be more environmentally friendly than all others. Good packaging depends entirely on the specific product (e.g. greasy, liquid, solid, fresh) and the respective requirements (e.g. long shelf life, convenience, ability to split into portions).
• The maxim of "as little as possible - as much as necessary" thus applies.
