The Main Classification Of Plastic Boxes

- Jan 23, 2019-

According to the different uses of the material, there are professional signs on the plastic box to distinguish

1-PET polyethylene terephthalate: It can produce carcinogens after 10 months of use. Plastics of this material have a high probability of being discarded after use, and are generally used as mineral water bottles and milk bottles. Not suitable for cold and overheated water, easy to precipitate carcinogen DEHP.

2-HDPE (High Density Polyethylene): It is not easy to clean and is easy to breed bacteria. It is not recommended for repeated use. Usually, cosmetic bottles and shower gel plastic bottles are suitable for this type of material.

3-PVC (polyvinyl chloride): It is easy to precipitate harmful substances in case of high temperature and oil, 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 cling film commonly used in daily life are all such materials. Wrap the food with plastic wrap and easily dissolve harmful substances in the presence of oil.

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

6-PS (polystyrene): heat-resistant and cold-resistant, is the material for making bowls of instant noodles and foamed snack boxes. If you can't put in the microwave, it will cause chemicals because the temperature is too high. Therefore, we should reduce the use of fast food boxes to pack hot food.

7-AB (Acrylonitrile Butadiene): Cannot be used for food packaging, but before 2008, Code 7 mainly refers to all plastics except 1~6. Plastic bottles for plastic bottles and water dispensers are usually '7'.

When using plastic packaging boxes, we should try to avoid high temperature, repeated use, etc., and hope to have more environmentally friendly plastic packaging boxes in the future.
