Zhejiang Shangfeng Group develops low-heavy metal corrugated board

Recently, the "low-heavy corrugated cardboard" researched and developed by Zhejiang Shangfeng Group Co., Ltd. passed the provincial-level new product appraisal of the expert committee organized by Shaoxing Science and Technology Bureau. Excessive heavy metals are harmful to the human body. In order to effectively control heavy metal pollution, relevant regulations for the "Heavy Metal Protocol" and "Electronic Garbage Law" have been issued in succession. Shangfeng Group uses heavy metal chelation and technology to effectively remove heavy metals introduced into corrugated cardboard. The technology adds appropriate amounts of complexing and precipitating agents such as EDTA (ethylenediaminetetraacetic acid), AJSC, and sodium sulfide to the pulp fiber and the production water, and the heavy metal content in the corrugated medium after the papermaking process is greatly reduced, reaching the UN The requirements of the "Heavy Metal Protocol". This technology is an innovation in the reduction of heavy metal content in the production of corrugated board. The product fills domestic gaps, has significant economic and social benefits, and can more effectively provide internationally accepted paper packaging containers for export goods.
