The deposit bags may only contain aluminum cans and PET bottles, they must not contain garbage, glass or other foreign objects. Fill the bags just enough. Overfilled or underfilled bags make handling and deposit flow more difficult. In the picture below you see what a perfectly filled bag should look like!
The bag used must be approved by Returpack. The approved bags are specially designed to endure the transport of aluminum cans and PET bottles. Approved bags are available from your beverage supplier.
