Food containers made of plastic are lightweight and not easily breakable, making them widely used. However, many people believe that plastic, despite its convenience, poses health risks. In particular, some think that disposable delivery containers inevitably release environmental hormones or microplastics. However, this belief is a clear misunderstanding, and experts warn that improper use of plastic containers can harm health.
Disposable Delivery Containers, Excessive Anxiety is Unnecessary... "No Problem with Single Use"
Professor Kang Sang-wook from Sangmyung University stated on the YouTube channel 'Health Rescue Team', "Some people think that plastic delivery containers emit harmful environmental substances by themselves," and added, "These containers are mostly made of PP, so they do not release harmful environmental substances."
However, he warned, "The problem arises when people feel it's a waste to reuse disposable containers multiple times," saying, "Over time, even if it is not visible to our eyes, the material weakens, cracks can form, and microplastics can be released from there." He continued, "During the process of washing and reusing multiple times, if dish soap enters through tiny cracks, there is a risk of ingesting residual detergent."
Delivery Containers and Side Dish Containers are Generally Made of PP and PE... Safe if Used Properly
Professor Kang mentioned, "Delivery containers and side dish containers are made of PP and PE plastic." What do these materials mean?
The Ministry of Environment and the Korea Environmental Corporation classify plastic materials into seven categories: △1 'PET' △2 'HDPE' △3 'PVC' △4 'LDPE' △5 'PP' △6 'PS' △7 'OTHER'. PP stands for polypropylene, which is lightweight and heat-resistant. It is suitable for food storage and can be reused.
HDPE is high-density polyethylene, which can withstand temperatures up to 100℃. It can be reused multiple times and is microwave-safe. It is mainly used for children's bottles, toys, and detergent containers. LDPE is also used to make plastic bags and gloves, and it is safe to use as a disposable item.
Usage Method is More Important than Material... If It Looks Worn Out at a Glance, Throw It Away Immediately
As Professor Kang said, having excessive anxiety about delivery containers is unnecessary. However, do not reuse them multiple times just because you feel it's a waste. If you feel it's a waste to throw it away, it is safer not to use it for food storage.
If there are many scratches or if the product has yellowed, throw it away immediately. Even if there is no deformation in the product, reusing it too many times can cause the coating to peel off, leading to microplastics being released. It is also recommended not to keep oily foods in plastic containers for long periods as they can react with the plastic.
Professor Kang emphasized, "If the color of the plastic side dish container has faded or if it clearly shows signs of being used for too long, it must be thrown away."
