1. The harmful effects of plastic containers
When using poor quality plastic containers to contain an assortment of hot foods or processed foods when reheating in the microwave at high temperatures, the additives or harmful ingredients in plastic containers will soak into the food. In the market, there are a few types of plastic that can withstand temperatures from 150 to 200oC. However, when using this type of plastic to produce food containers, the manufacturer has added some other additives to increase product quality and reduce production costs. These additives are not conducive to human health, so if you use the product in long-term, they can affect your health.
The best plastic for making food containers is PP (Polypropylene), which is non-toxic and very flexible. If the plastic used for food containers is recycled from waste plastic, it is very toxic because they only tolerate temperatures between 70 and 80oC, so when used for packaging hot food or exposure to high heat sources, the harmful ingredients can be released.

However, the products made from this plastic are often used one time because its surface is capable of accumulating bacteria and it is difficult to kill them just by using water to wash them normally. The plastic is used to make water bottles and 16.9 fl oz beverage bottles, such as the kinds used to hold mineral water, cola, syrup, and so on. This is the reason why you should not reuse such bottles.
- Type 2: HDPE is considered to be relatively safe because the ability to smell and accumulate bacteria on the surface is relatively low. However, the disadvantage of this plastic is its milky color. Therefore, people often use this kind of plastic for containing water, juice, and milk.

Furthermore, PVC is very susceptible to distortion when used for holding hot foods or exposure to high temperatures.

Type 5 is suitable for making plastic bottles and food storage containers. In fact, these types of plastics are quite safe for human health. However, you should choose the containers that have number 5 on the surface to avoid toxicity.
