How it's used
Commonly found on food labels and packaging to indicate the period during which a product remains safe or of optimal quality. While it refers to the technical shelf life, people often use it interchangeably with the concept of an expiry date. It is a formal term that you will see printed on goods rather than something you would frequently use in casual conversation.
Examples
Has this carton of milk passed its shelf life yet?
Remember to check the shelf life clearly when buying food.

Common phrases
extend shelf life
within the shelf life
Common mistake
Learners often confuse this with 有效日期, which specifically refers to the expiry date. While they are related, 保存期 focuses on the duration of storage, whereas 有效日期 indicates the final day the product is considered safe to consume.
