Which packaging options help extend shelf life?

• A. Cans, tetrapacks, bottles and pouches
• B. Packaging that protects from contamination and environmental factors
• C. No packaging
• D. Loose wrapping

Answer: (B)

Extending shelf life comes from packaging that acts as a barrier against contamination and environmental factors such as moisture, oxygen, light, and temperature changes. When packaging limits these exposures, microbes grow more slowly, moisture exchange is controlled, and oxidation and physical damage are reduced, helping the product stay safe and retain quality longer. That protective function is what makes this option the best one. No packaging provides no protection, so shelf life won’t be extended. Loose wrapping offers little barrier and won’t reliably protect against contamination or moisture and oxygen changes. While common packaging forms like cans, tetrapacks, bottles, and pouches exist, they extend shelf life effectively only when they provide this protective role.
