There are a few things to pay attention to when choosing a safe food container:
Choose containers that meet food safety standards, such as FDA (Food and Drug Administration) certification, EU standards, etc.;
Try to choose harmless materials, such as BPA-free materials;
Choose containers with good sealing to prevent bacteria and dust from invading the food;
Consider the size, shape and stability of the container to prevent food from leaking or tipping over during transportation or storage.
In addition, it is recommended to choose reusable containers and avoid using disposable lunch boxes, which is beneficial to the environment and can effectively reduce waste.
