Green packaging opens up new world of papermaking

In addition to the long history of corrugated cartons, paper cups, paper cans, and paper drums are the rapidly growing paper packaging containers in recent years. Although facing the competition of plastic and metal materials packaging supplies, due to its good recyclability, paper packaging products still have a very wide range of uses. Especially in recent years, the green packaging project and the strategy for sustainable development have accelerated, and the recycling of packaging materials has attracted particular attention. Therefore, it provides a vast space for the development of packaging paper. China's packaging industry has already listed green packaging as a development priority in its 2010 vision development plan. Therefore, the market potential of paper packaging products is very large. The paper packaging container has a light and beautiful appearance and is suitable for large-scale mechanized production, especially for the convenience of recycling, which has always occupied an important position in traditional packaging materials. In recent years, with the continuous development of research and development of green packaging materials, paper-plastic composites, paper-aluminum composites and other packaging products that are based on the combination of paper as a substrate and other properties have also been continuously introduced. At present, paper packaging supplies are not just simply packaged goods, but also have the effects of shock absorption and moisture barrier. The form of packaging also evolves from the multi-body packaging of general items to the individual packaging of items. From small cosmetic packaging to large packaging of important items such as motorcycles, refrigerators, and large-screen color TVs, it can be seen that paper packaging products are widely used. The green packaging includes the meanings of protecting the environment and the regeneration of resources. Countries in the world are implementing these requirements from two aspects: the development of new pollution-free packaging materials and the improvement of packaging waste recycling technology. China's economy has developed rapidly, and the types of packaging supplies required have also become increasingly diversified. Higher demands have also been placed on paper packaging products. For example, paper is made from natural fibers after a series of chemical treatments. In order to improve the whiteness of the paper and improve the sensory quality, most papers have been fluorescently whitened. According to studies and experiments in animals, fluorescent whitening agents are carcinogenic substances. Due to lack of supervision and safeguard measures, the use of whitened paper for food packaging is not uncommon in China. With the concept of "green packaging", packaging paper not only requires exquisite application, but also must meet environmental protection requirements.
