When it comes to plastic containers for hot food, it is important to choose food-grade plastic that is safe for food storage.

Polypropylene (PP) and Polyethylene Terephthalate (PET or PETE) are two types of plastic that are safe for hot food storage (12). 

Polypropylene is FDA-approved for food contact and has a high heat tolerance, making it a safer alternative to most other plastics (1).

PET or PETE is a clear, strong, and lightweight plastic that is a good option for storing water and food, even for the long term (2).

However, it is important to note that even for containers labeled "safe" for the microwave and dishwasher, experts caution that heat and plastic don't mix well.

Understanding Food-Grade Plastics

FDA-Approved Plastics

The FDA (Food and Drug Administration) approves certain plastics for use in food contact applications.

Food-grade plastics have been tested for safety and meet strict guidelines to ensure they don't contain harmful chemicals that could leach into your food.

Food Safe Plastics

Food safe plastics are non-toxic and FDA-compliant, making them suitable for storing and handling food.

These plastics are designed to be resistant to chemicals and have minimal risk of leaching harmful substances into your food.

Common Types of Plastics for Food Storage

Please note that the "BPA-Free" column in the table contains "Varies" because the BPA content of these plastics may depend on the manufacturer and specific product.

Always check the label or contact the manufacturer to verify if a container is BPA-free.

HDPE: High-Density Polyethylene

HDPE is a popular choice for food storage due to its chemical-resistant and mold-resistant properties.

HDPE containers are safe for hot food storage, making them ideal for use in the kitchen.

LDPE: Low-Density Polyethylene

LDPE is similar to HDPE but is more flexible, making it ideal for bread bags and produce bags.

Although it's chemical-resistant, it's not as heat-resistant as HDPE, making it less suitable for hot food storage.

PET or PETE: Polyethylene Terephthalate

PET plastic is commonly used for single-serve beverage bottles, vitamin bottles, and condiment bottles.

It's a clear, strong, and lightweight plastic that's safe for food storage, including hot food.

PP: Polypropylene

Polypropylene has a high heat resistance and is used for medication bottles and dairy containers.

It's FDA-approved for food contact and is a safer alternative to most other plastics.

PC: Polycarbonate

Polycarbonate is an impact-resistant and bullet-proof plastic that's also used in food storage containers. However, it's crucial to ensure that any polycarbonate containers you use for hot food storage are BPA-free.

Acrylic

Acrylic is a strong material that's also FDA approved for use with food.

It's an excellent option for storing dry goods but may not be the best choice for hot food storage.

Nylon

Nylon is a thermoplastic material commonly used in cooking utensils due to its durability and heat resistance.

While it's not typically used for food storage containers, it's an excellent option for kitchen tools that come into contact with hot food.

Tips for Safe Food Storage in Plastic Containers

Checking for the Food-Grade Rating

When choosing a plastic container for hot food storage, look for a food-grade rating or FDA approval.

This ensures that the plastic is safe for food contact and doesn't contain harmful chemicals.

BPA: A Plastic to Avoid

Bisphenol A (BPA) is a chemical found in some plastics that can leach into food and beverages, causing potential health risks.

Always choose BPA-free containers for food storage, particularly when dealing with hot food.

Alternative Materials for Food Storage

While plastics like PP and PETE are safe for hot food storage, some people prefer alternative materials for food storage.

Glass and stainless steel containers are excellent options, as they don't contain harmful chemicals and are durable, reusable, and heat-resistant.

Conclusion

When it comes to storing hot food, it's crucial to choose containers made from food-grade plastic that is safe for food storage.

PP and PETE plastics are FDA-approved, food-safe options that offer high heat resistance, making them suitable for hot food storage.

Always check for food-grade ratings and avoid containers with BPA.

For those looking for alternatives to plastic, consider using glass or stainless steel containers for your hot food storage needs.

FAQs

Is it safe to use plastic containers for hot food storage?

Yes, but only if the container is made from food-grade, FDA-approved plastic like PP or PETE. Always check for food-grade ratings and avoid using containers with BPA.

Can I use any plastic container for hot food storage?

No, not all plastics are safe for hot food storage. Stick to FDA-approved, food-safe plastics like PP and PETE.

What are some alternatives to plastic containers for hot food storage?

Glass and stainless steel containers are excellent alternatives to plastic for hot food storage, as they don't contain harmful chemicals and are durable, reusable, and heat-resistant.

How can I tell if a plastic container is BPA-free?

Look for a label or marking on the container that indicates it's BPA-free. If you're unsure, check with the manufacturer or choose an alternative material like glass or stainless steel.

Can I use a plastic container in the microwave?

While some plastic containers are labeled as microwave safe, it's best to avoid heating food in plastic containers whenever possible. Heat can cause chemicals from the plastic to leach into your food. Use glass or ceramic containers for microwaving instead.
