Polyethylene Terephthalate (PET or PETE) – #1
This plastic is common in soft drink and water bottles. It’s generally safe for single-use and can be recycled. However, it’s not suitable for repeated use, especially in hot conditions.
High-Density Polyethylene (HDPE) – #2
HDPE is used for milk jugs, detergent bottles, and more. It’s known for its strength and resistance to impact. This type is safe for food storage and is recyclable.
Polyvinyl Chloride (PVC) – #3
PVC is commonly found in plumbing pipes and some food wraps. It can release harmful chemicals, making it unsuitable for food storage.
Low-Density Polyethylene (LDPE) – #4
LDPE is often used for grocery bags and some food wraps. It’s considered safe for food contact, but it’s not readily recyclable.
Polypropylene (PP) – #5
Polypropylene is used for yogurt containers and straws. It is one of the safest plastics for food storage, as it has a high melting point and is resistant to chemical leaching.
Polystyrene (PS) – #6
This material is used for disposable cutlery and foam containers. It can leach harmful chemicals, especially when heated, making it unsafe for food storage.
Other (Various) – #7
This category includes various plastics that may contain BPA or other harmful substances. It’s best to avoid these for food storage.

Look for Food-Safe Labels
Always check if the container is labeled as “food-safe.” This ensures that the plastic has been tested and deemed safe for food contact.
Check Recycling Codes
Familiarize yourself with recycling codes. As mentioned earlier, codes #1, #2, and #5 are generally safe for food storage, while #3, #6, and #7 should be avoided.
Avoid Heating Plastics
When reheating food, avoid using plastic containers unless they are specifically labeled microwave-safe. Heat can cause leaching of harmful chemicals.
Consider Alternatives
If you’re concerned about plastic, consider using glass or stainless steel containers. They are durable, reusable, and free from harmful chemicals.

Clean Your Containers
Before using any container, ensure it’s clean and free from residues. Use warm soapy water and rinse thoroughly.
Store at the Right Temperature
Keep food stored at the right temperature to prevent spoilage. Refrigerate perishable foods promptly to maintain freshness.
Label Your Containers
Labeling can help you track when food was stored and when it should be consumed. This reduces waste and ensures food safety.
Use Appropriate Sizes
Choose the right size of containers for the amount of food you’re storing. Overpacking can lead to spills and contamination.
Troubleshooting Common Issues
If you encounter problems with your food storage, consider the following:
Odors or Stains in Plastic
If you notice odors or stains in plastic containers, try soaking them in a mixture of baking soda and water. This can help neutralize odors and remove stains.
Containers Not Sealing Properly
Ensure that the lid fits snugly. If it’s cracked or warped, consider replacing the container to maintain food safety.
Conclusion
Knowing what plastic is safe for food storage is essential for maintaining your health and ensuring food freshness. By understanding the types of plastics, checking for safety labels, and following best practices, you can confidently store your food without worry.
