Not long ago, Jinan Drake Co., Ltd. introduced a flame retardance tester for packaging materials (oxygen index meter) to meet the needs of flame retardance testing of special packaging materials. In recent years, the application of functional packaging materials has continued to expand, especially with the application of higher flame-retardant packaging materials, such as flue gas filter bags, aerospace paper, and heated paper lunch boxes. The evaluation of the flame retardancy of these materials requires more and more. Jinan Derek complies with the market needs to introduce an oxygen index tester. This equipment also satisfies GB2406-80 and GB/T5454.97 standards. The integrated design of the main engine and the combustion cylinder is simple and convenient, and it is equipped with a special igniter. It is safe and reliable. . The machine can also evaluate the flame-retardant performance level of ordinary paper, cardboard, film and other materials. Through the flame-retardant test of packaging materials, it can guide production, use flame retardants rationally, and develop functional flame-retardant packaging products. The successful launch of this equipment is of great significance to continuously improving the fire-retardant protection level of China's functional packaging products.
