Exploring Food Packaging: Materials, Techniques, and Sustainability

1. Why are plastics commonly used for packaging?

Plastics are not commonly used for packaging, as they are heavy, expensive, and cannot be moulded into different shapes.

Versatile - plastics can only be rigid and are not resistant to chemicals, making them difficult to use for packaging.

Why are plastics used for packaging?

Plastics are commonly used for packaging due to their versatility, resistance to chemicals, ease of printing, lightweight nature, and cost-effective production. These qualities make plastics an ideal choice for various packaging needs.

2. What are the main uses of food packaging?

To make the product more expensive

To cook the product before consumption

To reduce the shelf life of the product

Food packaging is primarily designed to preserve the product, protect it from damage, make it appealing to the consumer, and enable easier transportation. Other purposes such as cooking the product, increasing the cost, or decreasing the shelf life are not the main goals of food packaging.

3. What packaging technique can prolong the shelf life and slow down color deterioration of cold meats, smoked fish, cheeses, salads, and fresh pasta?

Cryogenic Freezing

Vacuum-Sealing

Direct Exposure to Sunlight

Modified-Atmosphere Packaging (MAP) involves modifying the air in a plastic container to prolong the shelf life and slow down color deterioration of various food items.
