Reuse of plastic boxes is more environmentally friendly and healthy

According to the different uses of the material, the general plastic box has a professional mark to distinguish it.

1-PET polyethylene terephthalate: Carcinogens produced after ten months of use. Plastics of this material have a high probability of being discarded after use, and are usually used as mineral water bottles, milk bottles, etc. It is not suitable for supercooled and superheated water, which is easy to precipitate carcinogen DEHP.

2-HDPE (High Density Polyethylene): Not easy to clean, easy to breed bacteria, it is not recommended to reuse. Usually cosmetic bottles, shower gel plastic wrap bottles belong to this material.

3-PVC (polyvinyl chloride): It is easy to separate out harmful substances in case of high temperature and grease, and is commonly used in raincoats, plastic toys, building materials, etc.

4-LDPE (Low Density Polyethylene): It is easy to produce harmful substances at high temperatures. Plastic bags and plastic wraps commonly used in daily life are all of this material. Wrapping food in plastic wrap and heating can easily dissolve harmful substances in the presence of grease.

5-PP (Polypropylene): The only material that can be used for microwave heating, very healthy material. It can be reused after careful cleaning, but generally the lid of the microwave plastic box is not made of PP, so it is recommended to remove the lid when heating.

6-PS (polystyrene): heat-resistant and cold-resistant, it is the material for making bowl instant noodle boxes and foam fast food boxes. You can't put it in the microwave, because the temperature is too high to produce chemicals, so we need to reduce the use of fast food boxes to pack hot food.

7-AB (acrylonitrile butadiene): can not be used for food packaging, but before 2008, code 7 mainly refers to all plastics except 16, the plastic label of plastic milk bottles and water dispensers is usually '7'.

We should try to avoid high temperature, repeated use and other links when using plastic packaging boxes, and hope to have more environmentally friendly and healthy plastic packaging boxes in the future.
