Developing Paper Packaging to Promote Sustainable Development of Environmental Protection Industry

Green packaging is a new concept created with the progress of society. It is a manifestation of human civilization. Green packaging is also called ecological packaging. From a technical point of view, green packaging products should meet the requirements of ecological and environmental protection from the selection of raw materials, manufacture of products, use and disposal of the entire life cycle.

Environmental Performance of Paper Packaging Materials The four major packaging materials, paper, plastic, metal and glass, cover almost all types of packaging products. Here we mainly study the environmental performance of paper packaging materials. From the reproducibility of resources. The continuous use of materials, recycling reusability, energy consumption and pollution of material processing, and processing cost are considered in several aspects.
(1) It is easy to realize production automation, and it is easy to adopt various processing methods.
(2) The price of paper and paperboard is relatively low, which is the most economic compared with other materials, whether it is price per unit area or unit price.
(3) Paper packaging is non-toxic and sanitary. It can be used once. It can also be recycled and recycled. It does not cause public hazards and saves resources.
(4) The raw material for papermaking is mainly wood. From the perspective of resource regeneration, wood has a unique advantage and good reproducibility. However, the consumption of forest trees in the world is far greater than that of newly planted forests. Moreover, the growth of forests does not have the ecological effect of the original forests.
(5) There are a lot of "three wastes" in the papermaking process. The formation of acid rain is related to the "three wastes" produced by papermaking. In this regard, paper is the least environmentally friendly material in the four major packaging materials.

Environmental Design and Development of Paper Packaging Environmental design and development of paper packaging must maximize the use of resources and energy, and minimize or eliminate the impact of packaging on the environment.
1. The implementation of packaging for reduced packaging satisfies protection and convenience. Under the conditions of sales and other functions, the amount of use should be minimal, and unnecessary packaging should be eliminated as much as possible. In many packaging designs, designers tend to focus only on the aesthetics of surface decoration while ignoring later social influences (environmental influences). Such as large packaging in the packaging, small packaging in the packaging, packaging layer, but the product only accounted for a small part of the entire packaging volume. Severe waste of materials, waste of resources, and increased pollution, so the design should reduce the amount of packaging materials and eliminate unnecessary packaging methods. The specific method is as follows.
(2) Reduce the amount of packaging material by using a method of compressing the volume of the product. Some commodities are flexible and will not affect the quality of the goods after compression.
(3) Using expansion technology. For electronic products that require multilayer packaging, expansion techniques such as three-layer corrugated cardboard can be used. Five-layer corrugated cardboard, etc. to enhance the safety of product transportation packaging, while reducing the material waste caused by multilayer packaging.
2. Recycling of paper packaging Currently, the output of paper and paperboard in China has increased year by year. Packaging paper and paperboard account for more than 50% of the total output of paper and paperboard in China. Per capita consumption of paper has become an important indicator of the economic development level and social civilization of a country. The recycling of paper packaging waste can reduce the resource consumption of natural fiber raw materials and solve the problem of shortage of packaging resources, thereby saving a large amount of packaging raw materials and energy, and has obvious economic and ecological benefits. Greatly reduce production costs, achieve greater social and economic benefits; reduce packaging pollution, is one of the important measures to protect the environment.
The comprehensive utilization of paper packaging waste is the basic principle and important measure to prevent environmental pollution, and it is also the most active and effective method to solve the packaging pollution.
(1) Recovery of waste paper For waste paper recovery, classified collection is the most effective method. Because it is easier to use the same type of waste paper to produce the same type of paper, using waste paper to produce high-grade printing paper will cause a decrease in production efficiency and an increase in production costs. In fact, once the waste paper is classified, it will become a different kind of papermaking raw material and become a useful material for human beings.
(2) Recycling of discarded cardboard Cardboard packaging waste can be reused to save packaging resources. Corrugated cardboard packaging has excellent commodity protection features. After initial use, some packaging protection performance is still very good. For example, you can use relatively strong. Flattened corrugated cardboard boxes can also be made from discarded corrugated board to make inner liners and trays. For discarded paperboard, it can also be combined with other waste materials (such as waste brocade, quilt cover, zero-point material, etc.) to create beautiful and simple boxes. Cardboard that is already unprotected by packaging can be collected and used as a raw material for reproduction.
China's waste paper processing technology has been significantly improved. In particular, waste paper deinking technology has matured. In addition, in recent years, China has introduced advanced waste paper processing equipment that has little damage to waste paper fiber and has the features of water saving, energy saving, and low fiber loss, and is suitable for processing various types of waste paper. The processing capacity of waste paper in China has been greatly improved, and China has already had the conditions to increase the recycling of waste paper. In addition, China should increase its enthusiasm for the promotion of resources, raise awareness of environmental protection among all people, make people aware of the importance of waste paper sorting and recycling, view waste paper as an “invisible forest”, and vigorously shape the ecological consciousness of “invisible forest”. Pass legislation to ensure the smooth implementation of waste paper sorting and recycling. The government should also give corresponding policies to support enterprises that use recycled paper to encourage research and development of waste paper processing technologies and equipment, and to promote the improvement of domestic waste paper utilization rate and regeneration rate.
