Storing food properly is crucial for maintaining both its quality and your health. With numerous container options available, plastic, particularly PET plastic, is a popular choice. But the question remains: Is Pet Plastic Food Safe? Understanding the safety profile of PET plastic is vital for making informed decisions about food storage in your home and ensuring the well-being of your family. Let’s delve into the details of PET plastic and its suitability for food contact.
Understanding PET Plastic: More Than Just a Number
Polyethylene terephthalate, commonly abbreviated as PET or PETE, is a workhorse in the world of plastics. Belonging to the polyester family, this thermoplastic polymer is incredibly versatile. You’ll find PET in clothing fibers that make up your apparel, in bottles holding your favorite beverages, and in containers designed for a wide array of food products. Its adaptability extends to manufacturing processes like thermoforming, further expanding its applications.

Before addressing “is PET plastic safe for food storage?”, it’s important to understand what designates a plastic as “food-safe” in the first place.
Decoding Food-Safe Plastics: The Numbers Game
When it comes to plastic food containers, safety isn’t arbitrary. There’s a system in place to help consumers identify safer options. Look for the recycling symbol, a triangle of arrows, usually found on the bottom of plastic containers. Inside this triangle is a number, and this number is key.
Plastics labeled with recycling numbers 2, 4, and 5 are generally considered the safest for food storage. These include:
- #2 HDPE (High-Density Polyethylene): Known for its strength and resistance to chemicals.
- #4 LDPE (Low-Density Polyethylene): Flexible and often used for squeeze bottles and food wraps.
- #5 PP (Polypropylene): Heat-resistant and commonly used for reusable food containers.
The Food and Drug Administration (FDA) has approved HDPE, LDPE, PET, and polypropylene for food contact, recognizing their safety when used as intended. Polypropylene, in particular, is often highlighted as a safe choice for food containers.
Plastic Container Number Guide: At a Glance
| Recycling Number | Plastic Type | Food Safe? | Common Uses |
|---|---|---|---|
| #1 | PET (Polyethylene Terephthalate) | Yes | Water bottles, soda bottles, food jars |
| #2 | HDPE (High-Density Polyethylene) | Yes | Milk jugs, detergent bottles, food storage containers |
| #3 | PVC (Polyvinyl Chloride) | No | Pipes, window frames, some packaging |
| #4 | LDPE (Low-Density Polyethylene) | Yes | Squeeze bottles, plastic films, food wraps |
| #5 | PP (Polypropylene) | Yes | Yogurt containers, reusable food containers, straws |
| #6 | PS (Polystyrene) | No | Disposable cups, takeout containers, packing peanuts |
| #7 | Other (e.g., Polycarbonate) | Varies | Water bottles, baby bottles (concerns with BPA) |
PET Plastic: Is It Truly Safe for Food Storage?
Now, back to our primary question: is PET plastic safe for food storage? The answer is generally yes. PET plastic, identified by the recycling number #1, is considered food-safe by regulatory bodies like the FDA.
Here’s why PET is considered safe for food storage:
- BPA-Free: PET plastic does not contain Bisphenol A (BPA), a chemical that has raised health concerns in some other types of plastics, particularly polycarbonate (#7).
- Chemically Inert: PET is largely unreactive and doesn’t leach harmful substances into food or beverages under normal use conditions.
- FDA Approved: As mentioned, the FDA has approved PET for food contact, signifying its safety for intended applications.
However, it’s important to note some considerations:
- Single-Use Nature: While PET is food-safe, it’s often designed for single-use applications, like disposable water bottles. Repeated use and washing can potentially degrade the plastic over time.
- Not for Hot Foods: PET is not ideal for storing very hot foods or for heating food in a microwave. High temperatures can cause PET to degrade and potentially release chemicals.
- Recycling is Key: While PET is recyclable, proper recycling is crucial to minimize environmental impact.
Plastics to Avoid for Food Storage: Numbers to Watch Out For
While numbers 2, 4, and 5, along with PET (#1), are generally considered safe, it’s wise to be cautious with other plastic types for food storage:
- #3 PVC (Polyvinyl Chloride): PVC can contain phthalates, which are endocrine disruptors. It’s best to avoid PVC for food contact.
- #6 PS (Polystyrene): Polystyrene, commonly known as Styrofoam, can leach styrene, a potential neurotoxin. Avoid using polystyrene containers for food, especially hot foods or liquids.
- #7 Other (Polycarbonate and others): This category is broad and includes polycarbonate, which may contain BPA. While BPA-free alternatives exist, it’s generally safer to opt for plastics with numbers 1, 2, 4, or 5 for food storage.
Frequently Asked Questions About Plastic Food Safety
What Are the Safest Plastic Containers for Food?
The safest plastic containers for food are typically made from HDPE (#2), LDPE (#4), PET (#1), and PP (#5). These plastics are considered food-grade due to their chemical inertness and resistance to leaching harmful substances. If you prefer to avoid plastic altogether, glass, stainless steel, and silicone are excellent safe alternatives.
What Material Is Best for Storing Food Safely?
For ultimate food storage safety, glass and stainless steel are often considered the gold standards. They are non-reactive, easy to clean, and don’t leach chemicals. Among plastics, HDPE, LDPE, PET, and polypropylene are the safest options. Always check the recycling number to make informed choices.
What Can I Use Instead of Plastic for Storing Food?
Excellent alternatives to plastic food containers include:
- Glass containers: Durable, reusable, and non-reactive.
- Stainless steel containers: Lightweight, durable, and don’t leach chemicals.
- Silicone food bags and containers: Flexible, reusable, and often oven-safe and freezer-safe.
- Beeswax wraps: A natural alternative for wrapping sandwiches, cheese, and produce.
Is There a Risk from Polypropylene in Food Containers?
Polypropylene (#5) is generally considered safe for food storage and is approved by the FDA. While some concerns have been raised about potential leaching at very high temperatures, polypropylene is widely used in reusable food containers and is considered a safe plastic option for everyday food storage needs.
Making Informed Choices for Safe Food Storage
So, is PET plastic food safe? For most common food storage applications, the answer is yes. PET plastic is a food-safe material that doesn’t contain BPA and is approved by regulatory agencies. However, being mindful of its limitations, such as its suitability for single-use and not for high heat, is important.
Ultimately, choosing safe food containers is about making informed decisions. By understanding plastic recycling numbers and the properties of different plastic types, you can confidently select the best and safest options for storing your food and protecting your health.
