As people's awareness of environmental protection increases, consumers not only require product packaging to have a novel and beautiful appearance, but also require packaging materials that are pollution-free, easy to recycle, and easy to decompose. However, traditional packaging materials not only consume a lot of resources, but also cause serious pollution, which is not conducive to environmental protection. In daily life, wheat, straw, reed, etc. are all common and well-known plant straw fibers, and most of them are burned or returned to the field, and are not actually used. CSL is a three-dimensional papermaking technology in which straw fibers are crushed and mixed with slurry and water to be injected into the mold through a pipe, and then molded into a three-dimensional papermaking technology. The products it produces have the characteristics of non-leakage, waterproof, oil-proof, refrigerated, heated and baked, pollution-free and degradable. The application of plant straw fiber in pulp molding is mainly based on the following aspects:
1. Food packaging: The main products are disposable straw environmentally friendly tableware, cake trays, etc. At present, food packaging is a category with a wide range of applications and a large number of products, which is universal. Disposable straw environmentally friendly tableware is a common tableware that can be used in catering, entertainment (such as KTV for dried fruits), various conference centers, etc. As my country pays more attention to white pollution, relevant laws and regulations have been promulgated to promote the development of straw environmentally friendly tableware.
2. Industrial packaging: straw industrial packaging products are commonly known as paper trays. It is made of various plant straws as raw materials, and is formulated into a certain concentration of slurry through hydraulic pulping and batching processes. The slurry is adsorbed on a special metal mold to become wet. The blank product, the formed wet blank is then dried, hot-pressed and shaped. The main product types are computer boxes, precision instrument component linings, cosmetic boxes, and so on.
3. Medical packaging: Pulp molding used in the medical field made of straw fibers is mainly used in hospitals and frontline disposable medical products, such as paper urinals, paper bedpans, handguards, etc. This type of product is widely used, and its advantage that it can be shredded into paper fibers and discharged into the hospital sewage system at one time, which can avoid cross-bacterial contamination. With the substantial improvement of medical standards, my country's investment in social medical security, more and more disposable medical products with higher sanitation and more convenient use, have created an incubation for the development of renewable straw fiber products. Convenient conditions, in the future, by increasing the research and development of such new products, straw fiber will make its own contribution to the development of the world's medical industry!
4. New building materials. The main types include decorative wall panels, decorative ceilings, high-density boards, and light-weight insulation materials. (1) Decorative wall panels and ceilings. It is a new type of indoor decorative wallboard material formed by 20 processes including straw fiber as raw material, beating, suction filtration, high temperature shaping, trimming and so on. (2) High-density board. (3) Light-weight thermal insulation building materials.
The application of plant stalk fiber in pulp molding products is a big topic, and it is also the requirement of the development of the times. The application of plant stalk fiber in pulp molding is far more than the above aspects, and there are more excavations and developments. space.
