New ideas for packaging environmental protection in developed countries

Environmental protection is a worldwide topic. The “green wave” is emerging in the global scope. The packaging industry must also consider environmental issues while developing. For this reason, some packaging concepts and some new ideas for foreign developed countries are now provided. Hopefully, food packaging companies Something to learn from.

Relieving environmental pressures focuses on material selection. At present, many European and American companies focus on the development of "green packaging materials" that meet environmental requirements. When selecting packaging materials, they try to use easily-processable materials and actively develop new types of packaging materials. Pulp forming and packaging are gradually replacing traditional plastic materials that are difficult to degrade. For example, a U.S. company has developed a reusable paper packaging mat that is made from old newspapers and then re-manufactured into such packaging, which can replace the now widely used non-degradable foam mats.

Consider environmental requirements and focus on packaging design. One is to use the same material or separable coexisting materials when designing the packaging. Packaging made from a single material is easy to recycle. For example, a pure polyester coke bottle without a high-density polyethylene pedestal appears on the market, which facilitates regeneration. Multi-layered composite materials must be considered for ease of separation without hindering reuse. If the aluminum beverage is coated with an organic coating on the surface, the organic coating can be burned without causing difficulties in recycling, and the composite paper-plastic packaging is difficult to separate for purification. The second is to design packaging that can be reused over and over again. The use of reusable packaging materials not only saves resources but also reduces pollution. It is strongly recommended that beer companies such as Asahi and Sapporo in Japan develop a longevity beer bottle that is 10% stronger than the original beer bottle, and the average life expectancy can be doubled. The third is to simplify the packaging as much as possible so that it is properly packaged. Excessive packaging causes waste of resources and also causes unnecessary environmental pollution. Some developed countries are advocating proper packaging and have introduced some regulations in succession. For example, in the United States, the degree of complexity of product packaging has been regulated in accordance with a certain proportion. If excessive packaging exceeds requirements, heavy penalties will be imposed, which will force manufacturers to simplify packaging. Japan even proposed the idea of ​​“zero packaging”.
Developing edible packaging focuses on functional choices. Food packaging is a big industry for packaging industrial products, accounting for about 70% of the packaging industry. Food packaging waste also has the greatest environmental pollution. Therefore, solving the problem of food packaging and waste is a major issue in the packaging industry. Developing edible packaging materials is a good way to solve the contradiction between the discarding of food packaging and environmental protection. Developing edible packaging is a new approach. Its goal is to pursue It is a packaging film that does not affect the flavor of the packaged food. The film is edible. For example, a company in Queensland, Australia, made a package of edible potato chips. People can eat the potatoes and eat them without causing them to be wasted. Japan has developed decapcened chitosan made from shell materials to make edible wrapping paper. The fast food noodles packaged in edible packaging paper can be directly cooked in a hot pot. The use of edible packaging not only facilitates consumer consumption, but also avoids packaging waste from polluting the environment. It is worth further research and promotion.
Recyclable resources can be used to make good classification and recovery. In view of the fact that packaging waste is a major problem of environmental pollution, various countries are trying their best to classify and recycle packaging waste for recycling. For example, the classification and collection of packaging waste in Germany is very good. It not only recycles a large amount of useful materials, but also uses waste to incinerate electricity to generate energy, and it also reduces environmental pollution. Finland and Japan attach great importance to the recycling of paper packaging after recycling. These all show that, on the one hand, it is an important work that can not be ignored by packaging companies to grasp the development of environmentally-friendly packaging new products and on the one hand to use renewable resources for waste packaging.
