Disposable plastic food containers are convenient, cheap, and easy to use. They come in various shapes, sizes, colors, and designs to suit different types of food and occasions. However, they also pose some health and environmental risks when used for storing and reheating food. In this blog, we will explore the pros and cons of using disposable plastic food containers for your meals.

 

How Safe are Disposable Plastic Food Containers for Heating?

One of the main concerns about using disposable plastic food containers is their safety when exposed to heat. Many plastic containers are not designed to withstand high temperatures, especially in the microwave or oven. When heated, plastic can melt, warp, crack, or release harmful chemicals into your food. These chemicals can include bisphenol A (BPA), phthalates, styrene, and dioxins, which have been linked to various health problems, such as hormone disruption, cancer, infertility, and birth defects .

According to the U.S. Food and Drug Administration (FDA), some plastic containers are safe for microwave use, as long as they are labeled as “microwave-safe” or have a microwave symbol on them. However, even these containers can degrade over time and leach chemicals into your food. Therefore, it is advisable to avoid heating food in plastic containers as much as possible, or use them only once and discard them after use.

 

What are the Chemicals that can Leach into Food from Plastic Containers?

The most common chemicals that can leach into food from plastic containers are BPA and phthalates. BPA is a synthetic compound that is used to make polycarbonate plastics, which are hard and clear. Phthalates are a group of chemicals that are used to make polyvinyl chloride (PVC) plastics, which are soft and flexible. Both BPA and phthalates can act as endocrine disruptors, which means they can interfere with the normal functioning of hormones in your body.

BPA and phthalates can leach into food from food grade plastic containers when they are heated, scratched, or exposed to acidic or fatty foods. The amount of leaching depends on several factors, such as the type and quality of plastic, the temperature and duration of heating, the type and amount of food, and the frequency and age of use. Some studies have found that BPA and phthalates can leach into food even at room temperature or in the refrigerator .

The health effects of BPA and phthalates are still under debate, as different studies have shown conflicting results. However, some evidence suggests that exposure to these chemicals can cause adverse effects on the reproductive, neurological, immune, and metabolic systems, especially in children and pregnant women . Some of the symptoms and diseases associated with BPA and phthalates exposure include obesity, diabetes, cardiovascular disease, asthma, allergies, infertility, low sperm count, breast and prostate cancer, and behavioral and developmental problems.

 

How can you Prevent or Reduce Leaching when Heating Food in Plastic Containers?

If you have to use disposable plastic food containers for heating food, there are some ways to prevent or reduce leaching of chemicals into your food. Here are some tips to follow:

  • Choose plastic containers that are labeled as “microwave-safe” or have a microwave symbol on them. Avoid containers that are marked with the number 3 (PVC), 6 (polystyrene), or 7 (other plastics, which may contain BPA) on the bottom.
  • Do not reuse plastic containers that are not intended for multiple use, such as takeout boxes, yogurt cups, margarine tubs, and water bottles. These containers are more likely to leach chemicals when heated or reused.
  • Do not heat food in plastic containers that are damaged, stained, or discolored. These signs indicate that the plastic has degraded and may release more chemicals into your food.
  • Do not heat food in plastic containers that are too small or too big for the amount of food. This can cause uneven heating and increase the risk of leaching.
  • Do not heat food in plastic containers for longer than necessary. The longer the food is heated, the more chemicals can leach into it.
  • Do not heat food in plastic containers that are covered with plastic wrap or lids. The plastic wrap or lid can melt or warp and contaminate your food. Instead, use a paper towel, wax paper, or a ceramic or glass plate to cover your food.
  • Transfer your food to a ceramic or glass dish before heating it in the microwave or oven. This is the best way to avoid leaching of chemicals from plastic containers.
  • Wash your plastic containers thoroughly after use with hot water and soap. This can remove any residue or dirt that may contain chemicals. Do not use harsh or abrasive cleaners or scrubbers that can scratch or damage the plastic.
