At present, China's packaging industry is increasingly demanding, and its scientific and technological content is increasing. It has become one of the important industries in China's national economy. It is predicted that from 2011 to 2015, the total output value of the packaging industry can reach 600 billion yuan, an average annual growth rate of 6%. By 2015, paper packaging products can reach 36 million tons, plastic packaging products 15.5 million tons, metal packaging products 4.91 million tons, glass packaging products 5.5 million tons, packaging machinery 1.2 million sets.
        It can be seen from the above data that plastic packaging plays an important role in the packaging industry. As one of the four major materials in the packaging industry, it has been well received by users, and the application of plastics in rigid containers and flexible packaging will increase. . In the case of rigid containers, such as plastic trays and plastic drums, the long-term cost is lower than that of fiberboard barrels due to reusability. Plastic vertical bags also have the potential to replace cardboard boxes as containers for dry goods such as pre-made cereals, sauces, etc. In addition, plastic bottles are increasingly used for the packaging of fruit juices and fruit drinks because of their light weight and collision resistance. In terms of flexible packaging, pouches and films in plastic products will continue to be useful in fast food and retail.
       Therefore, in general, the development of the industry is still very considerable. At the same time, the plastic packaging industry has already developed into the transportation packaging field, and has already developed into transportation packaging. Ultimately, it will force the “transport packaging” still based on metal. Plastics are the main replacement.
