1. What Is BPA? Why Are People so Afraid of It?
You may have seen the words “BPA-Free” in the news or on the packaging, but what is BPA? Why is it so feared?
What Is BPA? Where Is It Mainly Used?
BPA is a chemical material called bisphenol A. It used to be used in a lot of plastic containers, drink bottles, and milk bottles, especially those from earlier years. If you are still using some of the very old plastic take-out food containers with lids, chances are they contain BPA, but many take-out food containers have improved and are no longer used.
How Does BPA Affect the Human Body?
Simply put, BPA can interfere with the body's hormone system. Especially when small children and pregnant women use plastic products containing BPA, it may have an effect on the body. Some studies say it is related to endocrine disruption and fertility problems. Therefore, the FDA and many European countries have begun to restrict the use of BPA, and now most of the white take-out containers are labeled “BPA-free”, so that people can use them with peace of mind.
How Much BPA Is Used in Take-Out Containers?
Nowadays, most of the plastic take-out food containers with lids produced by regular manufacturers are BPA-free, especially those labeled “BPA-Free”. However, be careful if you buy take-out containers from unknown sources that don't specify what they are made of. It's safer to buy the ones with labeled materials and certifications.
3. There Are Several Common Disposable Lunch Box Materials. Which One Is Safer?
There are many kinds of disposable lunchbox materials. Which one is more reliable? Here we give you a brief description of several common ones.
PP Material: The Safest Choice, Microwaveable, BPA-free
PP is currently the most recommended material, especially suitable for plastic take-out food containers with lids. Not only does it not contain BPA, but it can also be directly put into the microwave heating, and will not be deformed, with no toxic odor. Now, many manufacturers use PP material to make hot lunch box, with the most assured.
PET Material: BPA-free, But Can Only Contain Cold Food
PET is highly transparent, and it's great for holding fruits, salads, or cold drinks. Many of the white take-out containers you see are made of this material. But PET can not be heated; a heating easily deformed, affecting safety. So it is only suitable to be used in cold food scenes; don't use it for hot rice and hot soup.
PS Material: No BPA, But Heating Is Not Recommended
PS material is mainly used in foam lunch box, does not contain BPA, but it is afraid of heat. Once heated, it is easy to collapse and may produce harmful substances. So now the environmental protection requirements are high, many restaurants have begun to use less of this material, switch to PP or PLA made of plastic take-out food containers with lids.
PLA And Pulp Containers: Natural Materials, Green Environmental Protection
If you are particularly concerned about environmental protection, then you can choose PLA or pulp molded food containers. This material is extracted from corn, sugar cane, and other plants, and is 100% BPA-free and will not pollute the environment. Nowadays, some brands that take the green route especially love to use PLA to make take-out containers, which are both good-looking and safe.
