means to minimize the use of packaging materials under the condition of satisfying various functions. It is understood that at present, experts have shown in the strength test of corrugated board that if the basis weight of corrugated paper is increased by 1g/m2, the basis weight of box board can be reduced by 1g/m2. Therefore, in the process of corrugated board production, this method can realize the lightweight packaging.
2. material return
refers to recycling used packaging products and processing them into new packaging products. At present, the recycling technology of wood packaging materials has developed to some extent.
3. Reuse
refers to the recycling of all or part of used wooden box packaging products, and it is not easy to give up reusable packaging products, thus reducing the production of packaging products. Environmental protection packaging and distribution service is to use the above materials to transport printers that customers send for repair. When the products are delivered to the customers, the packaging box will be brought back by the distribution staff for reuse. Moreover, when the company uses wooden packing boxes for recycling large output machines, it will recycle the wooden packing boxes according to the time required by customers.
4. Recycling of materials
refers to the recycling and reprocessing of used packaging products so that they can be used in different fields. Because there are a series of difficulties in realizing the recycling technology of composite materials, merchants begin to use some packaging materials made of single materials, which are beneficial to recycling, so as to realize the recycling of materials. At present, a pure polyester beverage bottle without high density polyethylene base has appeared on the market, and some plastic products that are difficult to degrade traditionally can be replaced by pulp molding packaging.
5. Refusing to use non-ecological materials
refers to refusing to use packaging products that are not conducive to ecological development or can cause the spread of diseases and pests. In terms of packaging materials, some developed countries as importing countries prohibit or restrict packaging products (wooden cases, straw bags, etc.) made of some original packaging materials and partially recycled packaging materials.
