Selection method of plastic box
The first is "pinch". It is necessary to select a packaging box that has a certain thickness and is not easily torn or deformed by squeezing. PP boxes are usually relatively strong, but in contrast, some packaging boxes are relatively thin, soft, fragile, and easily deformed when heated.
The second is "smell". Qualified packaging boxes should be free of odors. If you smell a pungent odor, either there is no sanitation and disinfection treatment, or there are chemical raw material residues, which are unqualified products that have not been tested.
The third is "look". When packing, you should carefully check whether there is a triangle mark and microwave instructions on the plastic box. The PP packing box is relatively safe and can also be heated in a microwave oven. Pay attention to the colorful box because it may contain Harmful ingredients.
