Does a sealed can guarantee shelf life?

Format and use

A seal is one packaging feature. Shelf-life support concerns the particular formula, materials, closure and storage conditions over time. Ask for the study and the specification it evaluates. Similar-looking cans, a raw-material certificate or a generic facility claim do not establish a finished product’s expiry period.
