Shandong Haihua Group Plastic Co., Ltd. has successfully developed biodegradable raw salt bags. The original salt series bags have the advantages of alkali resistance, corrosion resistance, and repeated use. Haihua Group added advanced technologies such as laminated rainproof film and light resistance in the woven bags, which greatly facilitated the midway transportation of raw salt. In addition, the company adds degradative additives to the raw materials of plastic-wrapping bags and packaging products, so that the plastic packaging materials become environmentally friendly products that can be dispersed without release of harmful substances in the process of use, effectively solving the problem of the current very tricky plastic-woven bags. . According to incomplete statistics, the major salt fields in Weifang City require more than 5.9 million plastic woven bags each year. Most of the salinization companies purchase them from Haihua Plastics. The company's plastic woven bags have already hit the international packaging market. The introduction of degradable raw salt bags will provide quality packaging bags for raw salt exports.
