News:As the major e-commerce platforms start their mid-year promotions, starting from June, nearly 400 million express packages flow across the country every day. However, during the interview, the reporter found that large boxes cover small boxes, and the packaging boxes are filled with plastic foam, and the goods can only be seen after tearing off layers of packages... Such excessive express packaging is still common.

  The reporter calculated that the volume of these removed packages was almost five times that of the purchased goods. Because many of them cannot be reused, they can only be sent to garbage recycling stations, becoming the "main force" of domestic garbage.

  Green packaging breaks through technical cost difficulties

  Properly solving the problem of excessive express packaging is not only imminent, but also an inherent requirement for industry transformation and upgrading and sustainable development. The key to "slimming down" express packaging is to start from the source and work hard on packaging design.

  CCTV reporter Tang Ying: In the research and development site of China Post Green Packaging Innovation Laboratory, this packaging proofing machine is making samples according to the design drawings of the research and development personnel.

  Gao Kang, Packaging Engineer of China Post Green Packaging Laboratory: Our boxes will go through physical tests such as drop, vibration, and impact after they are glued together to meet the verification of the safety of the contents in real scenarios. If it does not meet the standard, we will consider making some adjustments on the paper first, increasing the weight of the paper, then selecting and adjusting the material of the paper, and then re-drawing the drawings, and repeating such actions and testing until it meets our requirements. .

  In addition to cartons, various items frequently used in express delivery, such as bubble wrap and adhesive tape, will undergo multiple rounds of testing. The research and development personnel said that the tape that is often wrapped around the packaging is the focus and difficulty of research and development.

  Kang Li, technical director of China Post Green Packaging Laboratory: Compared with traditional ordinary tapes, (degradable tapes) may not be as strong as traditional tapes when packaged, reaching a level of 50%, and its cost is slightly lower Increased, nearly tripled.
