1. Adjective:
   • Treated to stay fresh longer than usual: Used to describe perishable goods, especially food and drink products, that have been processed or packaged in a way that extends their shelf life beyond what is typical for their untreated counterparts.

• Adjective:
  • We bought long-life milk for our camping trip because it doesn't need refrigeration.
  • The supermarket stocks long-life orange juice in the ambient aisles.
  • These long-life batteries are designed for use in remote controls.

Advanced Usage

Variants and Related Words

Notes on Meaning

• The term "long-life" specifically refers to a treatment or processing method applied to items that would otherwise spoil quickly. It is not simply a description of something that is naturally durable.
• It is commonly associated with dairy products (milk, cream), fruit juices, and certain baked goods.
• In other contexts, such as "long-life light bulb" or "long-life battery," the term is used more generally to indicate a product engineered for extended durability, though the core concept of an extended functional period remains.
