Is PP5 Microwave Safe? Everything You Need to Know

Do you worry about what kind of materials you can safely microwave? PP5 plastic is often used in food storage containers, but is it safe to use in a microwave? Find out the answer to this important question and learn how to keep your family safe.


Many people are concerned about the safety of heating food and beverages in plastic containers, due to the possibility of harmful chemicals being released into the food when heated. One type of plastic container, polypropylene (PP5), is deemed a safe material for many microwave applications, but special considerations must be taken to successfully and safely heat food or beverages in these containers.

This guide will provide information about what PP5 is and discuss safe guidelines for using PP5 containers in microwave ovens:

Types of Microwaves

There are a variety of different types of microwaves available in the market, and each uses a different type of material for its inner construction. This is important to keep in mind when deciding which type of microwave is best for you. The most common materials used in microwaves are polypropylene (PP5), ceramic, and stainless steel.

  • Polypropylene (PP5) is a lightweight plastic that can be used to line the inside walls and roof of certain microwave ovens. It has some non-stick properties, making it easy to clean and maintain. The advantage of using PP5 is that it keeps microwaves relatively affordable – however, due to its material composition it is not as heat resistant as many other materials, meaning it may need more regular replacements over time.
  • Ceramic microwaves feature an interior wall and roof made out of specially treated clay or porcelain glazes and enamels that are both durable and heat-resistant. Ceramic is also non-reactive with food surfaces (meaning there will be no chemical off-gassing), so it’s great if you plan on using your microwave regularly without worrying about contamination from hazardous materials or particles from the inner lining of your microwave.
  • Stainless steel microwaves have inner walls composed mainly from steel alloy single sheet construction with high nickel content for increased heat resistance. Because stainless steel does not corrode, rust or tarnish easily, this material provides excellent insulation against extreme temperatures or loadings – making stainless steel better suited for intensive use than PP5 or ceramic materials. However, stainless steel does tend to be more expensive than the previous two options mentioned here.

Safety Guidelines

When using any plastic wrap or container for microwaving, it’s important to follow safety guidelines. PP5 plastic is no exception. The primary concern when microwaving plastic is that it reflects and absorbs heat unevenly, causing warping and deformation. Additionally, some plastics contain volatile organic chemicals (VOCs), which have the potential to migrate into the food during the heating process.

When microwave-safe PP5 plastics are used correctly according to the manufacturer’s instructions, there should be no risk of migration of VOCs into your food. To use PP5 microwave-safe containers safely:

  • Check the bottom or side of your container for a label or symbol indicating it’s safe to use in a microwave oven
  • Follow any other safety guidelines on this label
  • Do not leave food covered in a PP5 container in the microwave for long periods – heat it only in short bursts and stir frequently
  • Don’t use these containers with temperatures higher than those indicated by their manufacturers, as they could warp or melt
  • Allow heated food to cool before serving or refrigerating it

Potential Risks of Using Microwaves

When heated in a microwave, plastics and Styrofoam may leach out endocrine-disrupting chemicals, which could potentially lead to a wide range of health problems, including infertility, cancer and birth defects. In addition, studies suggest that microwaving food in plastic containers can cause the release of potentially hazardous toxins into food. It’s best to avoid using plastic with microwaves at all costs and instead opt for ceramic or glass cookware.

In addition to the potential risks related to plastics, there is also concern about some substances used in paper plates or packages that can also be hazardous when heated in a microwave. Do not heat up foods in aluminum foil, paper towels or wax paper as this could potentially lead to burns due to sparks created by materials touching the walls of your oven.

Finally, beware of over-heating foods because it increases the risk of bacterial growth and food poisoning hazards.

Is PP5 Microwave Safe?

When it comes to microwaving food, a number of issues need to be considered in order to ensure safe and healthy meals. One particular type of plastic that is often used in food containers is polypropylene #5 (PP5), which can provide optimum safety for storage and heating.

PP5 is considered the safest option for microwaving, since it does not release any chemicals into food when heated and has a high temperature tolerance. However, some containers may be labeled with a symbol depicting an open microwave surface and should not be used in the microwave as they can melt or warp at high temperatures. Therefore, it’s important to check the labeling of your PP5 container before using it in a microwave oven.

In addition, you should make sure that the PP5 container is marked as “microwave safe” or “dishwasher safe” before placing it inside your microwave oven. Finally, PP5 containers should always be placed on a heat-resistant surface when microwaving food to prevent any burning or warping of the plastic. By following these tips for safely handling PP5 containers, you can enjoy safely prepared meals without worry.

Alternatives to PP5 in Microwave

Polypropylene #5 (PP5) is a type of plastic that is commonly used in the manufacture of food containers and other kitchenware, such as baby bottles, sippy cups and food storage bins. While PP5 is generally considered safe for use in a microwave oven, it can become soft or even melt if exposed to high levels of heat. For this reason, many consumers are looking for alternatives to PP5 in the microwave.

The safest choice is to avoid heating plastics altogether. Switching to glass and ceramic containers can eliminate any potential concerns about leaching chemicals into the food. If you must use plastic while microwaving, there are safer options. Look for polyethylene terephthalate (PET), polyethylene (PE) or polypropylene (PP3). These are some of the best plastics available and have been found to release fewer toxins compared with PP5 when heated in a microwave oven.

Be sure to check all plastics for labels before microwaving. If a container does not have an identifying label on it, err on the side of caution and don’t use it in the microwave. It’s also important to remember that any plastic may deteriorate over time and should be replaced if it becomes discolored or scratched. Finally, always take precaution when handling hot plastic containers after microwaving; wear protective cloths and potholders when necessary!


Microwave-safe plastics are marked with the code “PP5,” also known as polypropylene. These types of plastic items are considered safe to use in the microwave.

It is important to take a few extra precautions when using microwavable plastic containers in order to avoid spills or burns, such as never leaving microwaved food unattended or covering the food with a paper towel before heating. Additionally, it is important to ensure that all parts of the container have been thoroughly cleaned after each use and that it has not been overly heated.

By using common sense and following these guidelines, you can safely use products marked PP5 for preparing and heating food in your microwave.


Ultimately, it is up to you to determine whether using a PP5 container in your microwave is safe for your particular circumstances. Several factors should be considered when making this decision, such as the specific material of the container, its size, and any other potential risks or dangers associated with microwaving PP5 containers. It is best to exercise caution when heating food items in PP5 containers and invest in specialty vessels designed specifically for microwave use when available.

If you are ever unsure of the best option for reheating your meal, consult a professional such as a chef or nutritionist who can offer informed advice on the safest methods.
