What You'll Learn
Plastic is non-reactive, so it won't react with food or drinks
Plastic containers are favoured for storing food items because they are lightweight, cheap, and easy to handle. They have good strength and elasticity, making them durable and user-friendly. Plastic has replaced traditional materials like paperboard, wood, and metals for food storage due to these advantages.
One of the key reasons why plastic is preferred for food storage is its non-reactive nature. Plastic is inert, meaning it does not react with the ingredients or chemicals in food items. This ensures that the food's quality and integrity are maintained during storage. The non-reactive property of plastic is due to the presence of saturated chains within its molecular structure, which are difficult to break. As a result, food items can be stored without undergoing unwanted chemical reactions or spoilage.
The non-reactivity of plastic is particularly important when storing certain types of food. Acidic or fatty foods, such as tomato sauce or lasagne, are prone to absorbing more chemicals from their containers. By using non-reactive plastic containers, the risk of chemical leaching is reduced. This helps to maintain the safety and quality of the stored food items.
However, it is important to note that some scientists have raised concerns about the potential health risks associated with using plastic containers for food storage. Studies have shown that chemicals from plastic containers can "leach" or "migrate" into food and drinks, especially when storing hot food or heating food in plastic. These chemicals may include substances that are potentially hazardous to human health. Therefore, it is recommended to follow guidelines and use plastic containers that are specifically designed for food storage and to avoid using single-use plastic containers for this purpose.
To summarise, the non-reactive nature of plastic containers makes them a favoured choice for storing food items. Plastic's inert properties ensure that food quality is preserved, and it does not react with the ingredients. However, it is important to use food-grade plastic containers and follow safety guidelines to minimise potential health risks associated with certain chemicals in plastic.

Plastic is versatile and can be used for freezing, heating, and transporting food
Plastic containers are popular for storing food because they are lightweight, cheap, versatile, and easy to handle. They can be used for freezing, heating, and transporting food.
Plastic containers are versatile and can withstand freezing, heating, and reheating. They are commonly used to store food in the freezer and to reheat leftovers in the microwave. However, it is important to note that not all plastics are safe for microwave use, and only containers labelled "microwave-safe" should be used. Glass and ceramic containers are also safe for microwaving. When using plastic containers for freezing, it is important to ensure they are labelled "freezer-safe" and are moisture-vapour resistant, leak-proof, and easy to seal.
Plastic containers are also suitable for transporting food. Their lightweight nature makes them convenient for carrying meals and snacks on the go. Plastic containers are often used to take meals to work or school, or for storing food when travelling or picnicking. They are also commonly used in the food packaging industry, particularly for takeaway containers, due to their lightweight and cost-effective nature.
While plastic containers offer versatility in terms of freezing, heating, and transporting food, it is important to consider the potential health risks associated with using plastic. Some scientists have raised concerns about the chemicals in plastic and their potential to leach into food, especially when storing hot food or heating food in plastic containers. It is recommended to use plastic containers only for storing cold food and to avoid using them for heating or reheating whenever possible.
To minimise health risks, it is important to choose food-grade plastic containers that are specifically designed for food storage. These containers are made to prevent the transfer of non-food chemicals into the food. Additionally, following proper care and maintenance practices, such as hand-washing plastic containers and regularly inspecting them for any damage, can help ensure the safety of using plastic containers for freezing, heating, and transporting food.
