With the rapid development of express industry, a large number of express packaging waste is directly sent to the landfill or incineration, as a simple waste disposal, not only consumes a lot of raw materials, but also pollutes the environment. The fact that the recovery rate of plastic packaging materials in express packaging is less than 10% runs counter to the rapid development of the express industry and the requirements of environmental protection, which has become a burden for the development of the express industry.

With the vigorous advocacy of "circular economy", green packaging came into being in recent years. As a market leader in degradable packaging materials, Meijing has made a breakthrough in the field of fully biodegradable express bags through active research and development. Meijing company has developed a kind of recyclable biodegradable antibacterial express bag. The whole express bag is composed of biodegradable materials (PBAT + PLA + inorganic filler), which can be composted and degraded after being discarded; In addition, the special structure of biodegradable material self sealing strip technology is used to replace the traditional glue at the seal, which completely avoids tearing the seal at one time, so that the express bag can be recycled for many times, and the service life can reach 2 years, meeting the current government's recyclable and degradable policy.

For the sake of public safety and health, Meijing company actively explores the surface antibacterial technology applied to the recycling of biodegradable express bags. The Singapore patent 10201902068u currently used by Meijing company is a compound of metal powder (zinc, iron, titanium, tungsten and their alloys) and natural ingredients, with metal composition > 90%, The remaining 10% are edible components, which not only have high safety, but also effectively kill common superbacteria (such as multi drug resistant Staphylococcus aureus, vancomycin resistant Enterococcus and Pseudomonas aeruginosa, etc.), and effectively resist virus.

1020190268u Golden Shield product can effectively kill common superbacteria (such as multi drug resistant Staphylococcus aureus, vancomycin resistant Enterococcus, Pseudomonas aeruginosa, etc.) and effectively resist virus.
