Background
Synthetic paper, which has been called chemical film paper, polymer paper, plastic paper, etc., is made of thermoplastic polymer (such as polyethylene, polypropylene, polystyrene) and inorganic particles as raw materials through different production equipment and processing techniques, and is said to be a product of the combination of paper industry and plastic industry.
In the world (especially China) nowadays, the demand of paper raw materials becomes a new problem due to the gradual decrease of forest resources. The synthetic paper can solve the problem of raw materials, and more importantly, the raw materials are pollution-free, and waste materials generated in the manufacturing process can be recycled. The environment-friendly synthetic paper has the characteristics of low cost, excellent strength, water resistance and oil resistance, has wide prospects in function and application, and is suitable for various industries of people, commerce, industry and military.
The traditional synthetic paper takes high molecular polymer as a main raw material, calcium carbonate as an auxiliary raw material, and the content of the calcium carbonate is less than 40 percent, so the cost is relatively high, and the development of the paper is limited to a certain extent depending on petroleum. Recently, the technology is greatly developed, calcium carbonate is used as a main raw material, the content of the calcium carbonate is up to 80%, a high molecular polymer is used as an auxiliary raw material, the content of the high molecular polymer is less than 30%, and the high molecular polymer simultaneously has the characteristics of plastics and paper through the application of various new technologies. The production process of the environment-friendly paper is pollution-free, can be recycled and reused, and is a great reform of modern paper production. As a new type of paper, the excellent performance of environment-friendly paper is more and more obvious, the application is more and more extensive, the environment-friendly paper is expanded to a plurality of new fields, and a plurality of new products are continuously developed. The environmental-friendly paper has been developed for over thirty years abroad, with the enhancement of global environmental awareness, the common fiber paper causes a great deal of pollution, the development of the environmental-friendly paper is accelerated, new environmental-friendly paper varieties continuously appear, and the application range of the environmental-friendly paper is expanded.
