Two Green Packaging Newsletters

First, waste paper-plastic aluminum composite containers (commonly known as Tetra Pak) are favored by merchants and consumers because of their ease of use, good storage, and low price, but because they use paper-plastic aluminum composite boards as raw materials, waste Disposal has great difficulties. How to effectively eliminate the environmental pollution of discarded paper-plastic aluminum composite containers and make full use of waste paper-plastic aluminum composite containers has always been a difficult point in environmental protection. Recently, Guangdong Far East Food Packaging Machinery Co., Ltd., after research and experiment, successfully developed a set of technologies and equipment for the rational use of waste paper-plastic aluminum composite containers. Using this technology and equipment, the paper-plastic aluminum composite container can be successfully separated into resin, long-fiber all-wood pulp, and advanced metal coating aluminum powder with a high yield. It is said that it will treat 300 tons of paper-plastic aluminum composite containers, which can recover 30 tons of resin, 210 tons of long fiber pulp, and 15 tons of aluminum powder for high-grade metal coatings.

Second, the status of China's degradable plastics industry According to preliminary statistics, China's decomposing plastics research and development, production units have more than 100. The researched and developed varieties include light degradation, photobiodegradation, photo-oxygen biodegradation, high-starch content biodegradation, high-starch content biodegradation, high-calcium carbonate-filled photo-oxygen degradation, and biodegradation. The production volume of twin-screw masterbatch is about 40,000 tons (of which export volume is about 40%, and the domestic utilization is about 60%); the production of degradable plastic products is about 220,000 tons (of which the export volume is about 20%, and the domestic utilization is about 80%) ). The application of degradable plastic products in packaging has been widely used in ordinary packaging films, shrink films, shopping bags, garbage bags, cutlery, buffer packaging materials, etc., and has played a positive role in improving the environmental quality in China.
