Toxic and harmful to the body.
Disposable lunch boxes are made of plastic, so it is best not to use them for a long time. Plastics are mostly made of polyvinyl chloride. This chemical substance will release toxic substances when exposed to high temperatures, which can enter the body with food and endanger health.
Disposable foamed plastic lunch boxes and plastic bags containing food seriously affect our health. When the temperature reaches 65°C, harmful substances in disposable foam plastic tableware will penetrate into the food and cause damage to the human liver, kidneys and central nervous system.

At a glance, First, check whether there is a QS logo and number on the lunch box; secondly, check whether the surface of the lunch box is smooth and clean. Please keep this mark and whether there are impurities or black spots. Generally speaking, transparent plastic lunch boxes are produced using pure polypropylene (PP), which has a relatively high safety factor; brightly colored lunch boxes may use waste plastic, so the darker the color, the less safe it is. It is understood that more and more regular hotels now choose Lunchbox King’s packaging boxes. Lunchbox King’s packaging boxes are made of food-grade imported PP plastic without adding any additives to ensure health and environmental protection.
The second touch is to feel the strength of the lunch box. Lunch boxes produced using recycled waste or adding a large amount of industrial grade calcium carbonate and talcum powder are generally very poor in strength and will break if you tear them lightly. .
The third smell is to smell the lunch box to see if there is any peculiar smell. There will be no smell in the qualified lunch box.
