What is the maximum fill level for big tins of milk?

The maximum fill level for big tins of milk is three-quarters full. This limit is often established to provide adequate space for expansion, which can occur during processing, storage, or transportation. If a tin were filled all the way to the top, there would be a risk of spillage, which could lead to waste and contamination. Additionally, leaving some space in the container helps to maintain the quality of the product by minimizing the risk of oxidation or spoilage.

In contrast, filling the tins to other levels, such as half full or one-quarter full, would result in wasted capacity and inefficiency in packaging and shipping, which is not ideal from an operational standpoint. Thus, three-quarters full strikes a balance between maximizing the amount of product while ensuring safety and quality.
