Although plastic containers have cheaper prices than glass containers, buying these types of containers can ultimately affect your familyโs health over time because they tend to include hazardous substances. Therefore, this post will help you learn more about the harmful effects of some storage containers over others and the way to choose the best food storage containers for your family.
1. The harmful effects of plastic containers

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.
2. The way to choose the best food storage containers

- Type 1: All products that are made by polyethylene terephthalate (PETE) are quite safe and regarded as not being harmful to your health. 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.
- Type 3: PVC is very dangerous if you use the material to produce all kinds of plastic containers for food storage containers because of its ability to prevent the development of hormones and decrease fertility. Furthermore, PVC is very susceptible to distortion when used for holding hot foods or exposure to high temperatures.
- Type 4 and 5: They are quite similar in structure and functions. Type 4 is often used to produce all kinds of wrapping paper and food wrap film. 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.
- Type 6: This plastic is quite similar to type 1 because it is also used to create plastic products for one time use. However, this type of plastic also contains toxic substances that affect human health because, when exposed to high temperatures, the material can soak into the food.
- Type 7: It is a mixture of Polycarbonate and BPA. This is the plastic used for packaging food and it contains substances with no health benefits.
