Jewelry packaging box should be easy to reuse or easy to recycle. This is the most practicable step in developing green packaging materials at this stage. It is the most active waste recovery disposal method. The currently used polyester beverage bottles, bottles, glass beer bottles can be reused many times. You can't reuse it, break it up as much as you can, and melt it again. Many recycled waste paper and paperboard are used as raw materials for papermaking, and some can provide high quality super - pressure paper products for customers. Old box like some milk cartons typically contain 75 percent fiber, 20 percent plastic and 5 percent aluminum. Through processing, the fiber has been purified and made into new paperboard to produce carton packaging products. But plastic and aluminum can be heated to 500 degrees Celsius without oxygen, converted into gas and fuel, and the last aluminum is made of aluminum bricks that can be sold to aluminum products. The waste of jewelry packaging box can degrade and corrupt, not form permanent garbage. The world is studying biodegradable plastics to address the serious environmental problems posed by plastic's inability to break down. Degradation principle is through the role of the microbial soil and water, or through the role of ultraviolet ray in sunshine, make plastic split degradation and reduction in the natural environment, the ultimate in to ecological environment in the form of non-toxic, and the nature. By studying the methods of waste paper and wood waste, it not only helps to reduce the carbon dioxide production, but also plays an important role in environmental protection, and is beneficial to the profit of papermaking enterprises. In addition, the sale of the goods of the old paper dealer is also well solved. Packaging products are collected from raw materials, processed, manufactured products, products used, waste recycling, and the whole process of the final treatment shall not be caused by the human body and the environment. Packaging materials should be harmless to humans and creatures. Packaging materials should not contain toxic elements, heavy metals, or quantity should be controlled under the relevant standards. |
