Disposable meal box: The shelf life is about 4 months, and it is not suitable for storing high-temperature food. Generally, it cannot be heated in a microwave because its main raw material is polystyrene, which can cause the occurrence of dioxins at high temperatures above 65 ℃ and has been proven to be a carcinogen.
Disposable tablecloth: Shelf life of 6 months. As it can release sulfur dioxide in natural environments, it is not suitable to be placed on the dining table for a long time. Assuming it must be used, it is recommended to lay it on again before use and recycle it promptly after use. Disposable toothbrushes: Disposable toothbrushes used in hotels are mostly sealed and have a shelf life of about 8 months.
Disposable comb: With a shelf life of about one year, it is mostly made of plastic products. It not only causes static electricity when in contact with hair and scalp, but also releases toxic substances such as sulfur dioxide, which can lead to dandruff and dermatitis.
Disposable tissue: mostly made by cutting open original roll paper and directly packaging it. It is prone to chemical shock when in contact with air. It is recommended to use it within two days after opening
Disposable mask: With a shelf life of 1 year, expired masks not only fail to isolate bacteria, but can also release substances that corrode respiratory mucosa due to material degradation, triggering asthma.
