Its robust nature makes it suitable for both cold and hot food storage, making it one of the safest options available.
PVC (Polyvinyl Chloride) – Recycling code 3
Avoid using PVC for food storage whenever possible. This plastic, commonly found in cling wraps and certain food packaging, can leach harmful chemicals like BPA and phthalates. Look out for uPVC (unplasticized PVC) as a potentially safer alternative, although it’s not commonly used in food packaging.
LDPE (Low-Density Polyethylene) – Recycling code 4
LDPE is prevalent in bread bags, grocery bags, and some food wraps. While generally safe for cold storage, it’s not recommended for hot foods due to its low melting point. Be cautious when using LDPE containers for storing leftovers or reheating food.
PP (Polypropylene) – Recycling code 5
Polypropylene is a versatile plastic often found in reusable containers, yoghurt tubs, and bottle caps. It’s considered safe for most food storage applications, offering a good balance of durability and safety.
Other Plastics (PS, PC)
Other plastics, such as PS (Polystyrene) and PC (Polycarbonate), are less commonly used in food storage but may still be encountered. It’s crucial to check for “food-grade” labelling when using these plastics, as they may contain additives or chemicals unsuitable for storing food.
Safest Plastics for Food Storage
Selecting the appropriate type of plastic container is essential for ensuring the safe storage of food. Among the various options available, HDPE (High-Density Polyethylene) and PP (Polypropylene) are considered the top choices to maintain the freshness and purity of food.
Let’s delve into why HDPE and PP are the go-to plastics for food storage.
HDPE (High-Density Polyethylene), marked with recycling code 2, is renowned for its durability and resistance to chemicals. This type of plastic is commonly used in food-grade containers, including milk jugs, juice bottles, and food storage containers. HDPE is known for its non-leaching properties, meaning it won’t release harmful chemicals into your food, even when exposed to varying temperatures. Its sturdy construction also makes it suitable for freezing food without the risk of cracking or warping.
PP (Polypropylene), identified by recycling code 5, is another excellent choice for food storage containers. PP is highly resistant to heat and moisture, making it ideal for storing both hot and cold foods. It’s commonly used in microwave-safe containers and reusable food storage products. Like HDPE, PP is considered food-safe and does not leach harmful chemicals into food, ensuring the safety of your stored items.
Both HDPE and PP offer peace of mind when it comes to food storage. Their inert nature means they won’t react with the food stored inside, preserving its flavour and quality. Additionally, these plastics are easy to clean and maintain, making them a convenient choice for everyday use in the kitchen.
Additional Factors for Safe Food Storage
When it comes to keeping our food safe and fresh, the type of containers we use matters more than we might realize. That’s why it’s crucial to pay attention to additional factors beyond just choosing any plastic container. Here are some key considerations to ensure you’re storing your food in the safest possible way.
Importance of Choosing Food-Grade Containers
First and foremost, it’s essential to select containers that are explicitly labelled as food-grade. These containers are designed to meet strict standards set by the FDA (Food and Drug Administration) to ensure they are safe for storing food. By opting for food-grade containers, you can have peace of mind knowing that they have been rigorously tested for harmful chemicals and are suitable for storing consumables.
