Which packaging types are cited as examples for extending shelf life?

• A. Glass bottles only
• B. Cans, Tetrapacks, Bottles and Pouches
• C. Cardboard boxes only
• D. Plastic wrap only

Answer: (B)

Packaging choices extend shelf life by creating barriers to moisture, oxygen, light, and contamination, and by sealing the product to minimize exposure after processing. The option that includes cans, Tetrapaks, bottles, and pouches reflects the range of common packaging technologies used to achieve these protections. Cans provide an airtight metal barrier and are often heat-processed, giving strong protection against oxygen and microbes. Tetrapaks combine multiple layers, including aluminum foil, to block light and gas transfer while remaining lightweight. Bottles offer a secure seal with a cap and can be made of glass or plastic, providing another reliable barrier and easy product containment. Pouches use laminated films that can deliver high barrier properties in a flexible form and can be sealed to protect contents from air and moisture. Together, these packaging types illustrate the practical ways shelf life can be extended. Choosing only glass bottles, only cardboard boxes, or only plastic wrap misses other effective packaging methods and does not capture the full range of options used to preserve products over time.
