Can You Microwave Ziploc Bags Safely?
Yes, you can microwave Ziploc bags. The Ziploc bags are safe for defrosting and reheating in microwaves. However, people hesitate to use it in the microwave because they believe that heating plastics emits harmful chemicals to delicious food.
According to the Ziploc company, harmful chemicals from plastics form at temperatures of more than 1500 degrees F. Since home microwaves do not reach that high, there are no risks of exposure to harmful chemicals.
But the Ziploc bags are not always safe, we will talk about it later. First, let’s study some basic things.
What Are Ziploc Bags Made of
Ziploc bags are made of a product known as film. The film, as the manufacturers call it, is a thin, clear plastic with either low-density polyethylene (LDPE) or high-density polyethylene (HDPE).
Low-density polyethylene has recycling number #4, and high-density polyethylene has recycling number #2 to show how you should recycle the bags.
Normally, packaging plastics have numbers corresponding with polymers that are used. You can see the numbers at the base of the containers. However, Ziploc bags are dioxin-free, BPA-free, have a recyclable design, and are not made from recycled materials.
The good thing about this material is that it can withstand freezing and high heating temperatures. Although it is safe for use with foods, a higher temperature of over 1500 degrees F makes it emit toxins.
What Kind of Unhealthy Condition May Occur When You Microwave Ziploc Bags
Although Ziploc bags are safe, some conditions may occur in your microwave. The content of the Ziploc bag may expand, realizing steam. In other words, if the bag is cooked, it can mess up, causing a potential hazard.
Due to that, you should be aware of the following conditions:
1. The Steam when microwaving Ziploc Bags
When microwaving Ziploc bags, you should be aware of the safety hazards even if the food turns out great. For instance, steam can construct in your cooked food. If you do not handle the Ziploc bag carefully, you may burn your hands, causing unnecessary injuries.
To avoid such incidents, leaving the Ziploc bag open while microwaving is important.
2. Ziploc Bags MAy Melting
Ziploc bags are designed with thin plastics that melt on exposure to high temperatures, especially when the bag is empty. And a Ziploc that is melted can get into the food burning your skin, hence hazardous and worth taking risks.
3. Identifying the Products
It can be hard to tell the kind of product you are placing in your microwave if you do not use the name-brand Ziploc bag. Normally, some bags are designed with PVC plastic, making them unsafe for reheating, unlike polyethylene. Placing the product in a microwave may emit harmful dioxin to your favorite meal.
4. Harmful Chemicals
The Ziploc bags are designed with polyethylene plastic that is food safe without harmful chemicals. But, polyethylene releases dioxin chemicals on exposure to top heat.
As mentioned earlier in this article, home microwaves do not become hot enough, releasing dioxin. But you should be aware that the oils in the food may concentrate heat, causing health hazards.
How to Microwave Ziploc Bags Safely, the 5 Steps
1. Find the Right Ziploc Bag
Ziploc offers a line of bags that are safe for microwaving. However, it does not matter whether you are using other off-brand options; ensure that the bags are designed for microwaves. Some other bags may emit harmful chemicals to your favorite food, messing up.
So check the label on the Ziploc packaging for information on how to use it; some may include maximum temperature and safety information.
2. Fill it Appropriately
When you microwave the Ziploc bag, it will expand and emit steam. So, it is important to ensure that the Ziploc bag is not full. To fill it appropriately, it should be half full so that the content does not rise near the top.
3. Place it in the Microwave- Safe Dish
Ziploc bags may tip over as they are not designed to stand on the finish. Besides, the tears or holes in the Ziploc bag may leak, destroying your lovely microwave. Due to that, it is good to put the bags in a shallow plate or bowl to hold any mess.
4. Unseal the Ziploc Bag
Any food in high moisture can emit steam on heating, making your meals soggy or creating pressure making them burst. Due to that, it is good to leave a slight opening at the opening for steam to vent.
5. Select the Lowest Power Setting
Ziploc bags are great for reheating and defrosting food and not cooking. But why not for cooking, you ask? Cooking needs high temperatures that can cause some dangers that we mentioned earlier in this article.
So, it is important to use a lower power setting of about 50% or lower to avoid the dangers, and the power is perfect for reheating or defrosting in less time.
Are Ziploc Bags BPA-Free?
The answer is yes, Ziploc bags are BPA-free. The high-density polyethylene and low-density polyethylene make Ziploc bags free from BPA. According to the Ziploc manufacturer’s website, SC Johnson states that their products are free from BPA.
BPA is used in several plastics, such as water pipes and food storage containers.BPA can contribute to health complications such as asthma, prostate cancer, and breast cancer. Due to that, many plastic manufacturers are reducing the use of BPA, although you can get it in a scary amount of places.
How Long Can You Microwave a Ziploc Bag
There is no clear answer to the reheating and defrosting standards by the manufacturers. However, you can microwave a Ziploc bag on low to medium power and use ½ a minute increment.
As mentioned earlier, you should consider safety first by ensuring that the Ziploc bag is unsealed to avoid steam building up. Besides, you should keep checking it at intervals of ½ a minute to prevent overheating.
Another thing you should keep in mind is that the Ziploc bags will begin to melt at high temperatures of more than 195 degrees F.
How Hot Can You Microwave Ziploc Bags? the Temperature
Ziploc bags can only withstand mild hot temperatures. Therefore, keep the temperature at about 170 degrees F or less while microwaving.
Using the Ziploc bags at a higher temperature can deform these bags permanently and make the bags melt into a puddle.
For instance, at about 195 degrees F, the bags will begin to soften. And if you put the bags in boiling water, they will melt at about 212 degrees.
When You Can’t Microwave Ziploc Bags: the 2 exceptions
As discussed earlier, Ziploc bags are ideal for defrosting, reheating, and not cooking. Cooking in the Ziploc bags is unsuitable since they are not structured to withstand the high temperatures needed to cook meals.
In addition, it is good to cut your food into small and uniform pieces if you meal prep in the Ziploc bags. Doing so will help lower the time needed to reheat foods and lower microwaving time, minimizing overheating risks. With that said, here are two exceptions:
Do Not Overheat
When microwaving, small meal quantities take about ½ a minute or less, and anything over that creates unsafe temperatures in the Ziplock bag. However, if you want to microwave a little longer, consider doing it in intervals of ½ a minute and keep checking as you adjust the bag.
Do Not Re-Microwave
Reusing plastic bags is good for the environment and not good for the microwave. With time, the plastic may degrade, emitting many chemicals into the foods and risking leakages.
