Multi-product use
Returnable transport packaging designed to carry and protect many different types of products must meet a longer list of requirements. Often the result is a compromise. One example of a compromise is to decide if the packaging, in this case a tray, should be ventilated or not. Certain products require ventilation in order to keep their freshness, while other types of products must be kept in a completely closed storage to avoid contamination from outside or to prevent the risk of liquids leaking from carried products, which may contaminate the outside.
