The environmentally-friendly carton packaging material is made by using waste newspapers and waste paper products as raw materials, and is prepared by vacuum-adsorption molding on a special mold which is pulped and blended into a certain concentration of pulp (which can also directly use raw pulp such as wood pulp and mash).

An antimicrobial packaging material that has the function of reducing and inhibiting microorganisms in the food package so that it can stop growing or inactivating. We generally classify this material as mobile, regenerative, adsorbable, and immovable. At the same time, it will not have any impact on the quality of the food.
The surface of the packaging material is treated with an antistatic agent or subjected to a deep composite treatment to reduce the electrical resistance of the original material and improve the electrical conductivity, thereby achieving the purpose of eliminating static electricity. In general, the antistatic agent has a simple process, low cost, convenient production, and no special requirements on equipment, and thus occupies a certain position in actual production. This is the mainstream of the current popular, and is also the development direction of anti-static bags in the future.
The person in charge of a waste recycling station said that different types of garbage will be distributed to various places, and cartons and cartons can be reprocessed. From the current domestic conversion rate, about 100 kg of waste paper can be converted into 80 kg new. paper. However, the bags are not easy to handle, because most of the bags are covered with tape, which is somewhat difficult to recycle. The plastic bags used for express delivery are often complex in composition and contain industrial waste. They cannot be reprocessed or degraded, and most of them are used for landfill. At present, the plastic courier bag made of polyethylene material is used more, which has the characteristics of low cost, convenient use and good waterproof performance. In addition to the use of customized courier bags by major courier companies, there is now the online shopping industry, many merchants in order to give customers a good image, as well as enhance the image, and play a promotional role, but also customize their own express delivery bag.
