In 2019, U.S. consumers shopped an average of 1.5 times a week. While most of us focus on the taste and price of food, we might also stop and think about how the food is packaged and how it benefits everyone who goes grocery shopping, no matter how often.
Packaging that is durable, strong and corrosion resistant is one of the many reasons we have a safe food supply: it protects the food. It is also efficient and convenient to transport food.
Let's take a closer look at the main functions of food tin packaging: safety, protection, convenience, efficiency and information.
Safety and Protection - Food packaging helps extend shelf life. This means keeping food safe for a longer period of time. Exposure to oxygen can lead to spoilage, so some foods require airtight packaging. Losing or gaining moisture can also be a problem. You don't want your food to make you sick, and food packaging prevents the entry of microbes that cause foodborne illness.
Packaging materials must also be safe. The U.S. Food and Drug Administration (FDA) regulates the safety of any substances that come into contact with food by inspecting them. While some migration may have occurred over time, the levels detected were not high enough to be considered harmful.
The packaging must also protect the food from being crushed or damaged - no one dares to ship eggs in a paper bag.
Convenience, efficiency and information - the science of packaging makes it easy to pick what you need, and in moderation. You can store your food, open the package, see what you're eating, and dispose of it properly when it's no longer fit for use or reuse.
Packaging is also your main source of information about the inside of a product, such as nutritional value, ingredients, and expiration dates. Some packages also come with food safety tips and cooking instructions, and sometimes even a recipe for a new dish!
Packaging also helps us track food when food is recalled or a product goes wrong, which can make us sick. According to IFT's Center for Global Food Traceability, Traceability allows companies to "track products through the supply chain to improve food safety, reduce risk, avoid devastating health consequences, and cause economic damage to the food system." Unique barcodes on packaging help Tracking products from one point to the next makes it possible to find products anywhere in the food system.
