The raw materials of black and gray packaging bags are recycled materials, most of which are processed from domestic waste and chemical raw materials, and the natural cost is low. More than 70% of the packaging bags used by most express companies in Hangzhou are black and gray materials sold online. The secretary general of the International Food Packaging Association revealed that there are a lot of harmful substances left in the packaging bags made of recycled materials. Not only may skin allergies and other symptoms occur after touching, but even if these packaging bags are piled up around the desk, the smell will also be emitted. Affect physical health. Cheap plastic bags start at 0.1 yuan and paper bags start at 0.9 yuan. In the past two days, Ms. Li from Hebei had a case of skin allergy because of touching the express packaging bag, which made many consumers worried. What material are the express packaging bags received on the market made of? Is it really poisonous? The packaging bags are divided according to the material, there are several kinds of paper and plastic. There are several types of plastic materials, and the price varies according to the size and color. “The most used one on the market is the 0.1 yuan gray-black packaging bag, which is made of recycled materials. The green version is half-new material, half of which is recycled and half of new material. The white version is made of new material, and the price is higher. It is 0.25 yuan. Another material, the price of paper packaging bags is much higher than that of plastic bags. The approval starts at 0.9 yuan, and if you want to print a LOGO, you will have to increase the price.” A reporter from the Commercial Daily found that the gray-black made of recycled materials The packaging bag is used by many express companies such as Yuantong, Zhongtong and Yunda.

Only a few companies such as SF Express, EMS, and the Federation do not use this packaging bag. The darker the color of the bag, the more likely it is to use toxic recycled materials. According to industry insiders, it is precisely because the wholesale price of the packaging bag is so different that express delivery companies will use gray-black packaging bags in order to save costs. “Many private express delivery outlets are contractual in nature. The packaging bags and express delivery sheets all need to be paid for by the contractors themselves. The merchants must choose the cheapest ones.” According to YLTpacking in China, the darker the color of the bag, the more likely it is to use waste, relatively speaking. Consumers can also judge by the smell. The gray-black plastic bag can smell peculiar smell when the nose is close to it, or breathe in the plastic bag and dip it with hot water. The bigger the taste. “Ordinary bags and good bags have no smell. The more pungent the smell is when it is heated, it must be waste plastic.” Consumers must wash their hands after touching the express package, and after unpacking the package, the express package must be timely.
