Green packaging materials will gradually replace refractory plastics

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 materials that are easy to handle and actively develop new types of packaging materials. Pulp forming packaging is 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.

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.

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 a certain proportion. If excessive packaging exceeds the requirements, heavy penalties are imposed. This forces manufacturers to simplify packaging. Japan even proposes zero packaging.

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 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 A packaging film is made that does not affect the flavor of the packaged food and is edible.

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.
