Which factor is usually included in open dating on product packaging?

The inclusion of the expiration date in open dating on product packaging is essential for consumers, as it indicates the date until which the product is expected to retain its intended quality and safety for consumption. Open dating allows consumers to make informed decisions about the freshness of a product, particularly for perishable items such as food. This practice is significant in contexts where safety and quality are paramount, ensuring that customers are aware of the timeframe for optimal use.

While weight of the product, price per unit, and manufacturer's warranty information provide valuable details, they do not specifically pertain to the concept of open dating, which primarily focuses on the product's shelf life and quality assurance.
