Shelf Life Management Knowledge
Importance of Shelf Life
Shelf life is an important indicator of product quality and safety, ensuring consumers receive products that meet standards while helping businesses avoid economic losses and reputation risks caused by expired products.
Shelf Life Characteristics of Different Products
Food products: greatly affected by temperature and humidity; Pharmaceuticals: need strict storage conditions; Cosmetics: usually contain preservatives, pay attention to usage period after opening; Other products: different shelf life requirements based on materials and purposes.
Shelf Life Calculation Methods
Shelf life calculation is based on production date plus the specified shelf life period. This tool supports calculation in days, months, and years, and can accurately handle special cases such as month ends and leap years to ensure reliable calculation results.
Warning Period Setting Tips
Reasonable warning period settings can help handle expiring products in advance. Perishable foods are recommended to have a 3-7 day warning period, pharmaceuticals 1-3 months, and long-term storage products can have longer warning times.
Best Practices for Shelf Life Management
- First-In-First-Out (FIFO) Principle: Prioritize using and selling earlier produced products to avoid expiration due to inventory backlog.

- Proper Storage: Strictly follow temperature, humidity, and other conditions required by products to effectively extend shelf life.
