Green plastic packaging needs to improve technology from many aspects

The packaging industry has gradually become one of the important components of China's national economic development. However, at present, there are many inconsistencies in the packaging industry in China. This dissonance is related to the utilitarian nature of the company and is also related to the fact that the relevant technical standards of the country have not been updated in a timely manner. It is also related to the fact that the illegal cost of the company is too low.

Green packaging is a major trend in the development of the world packaging industry, and food safety is the focus of China's current and future years, both of which have a direct impact on the development of plastic packaging materials.

Green plastic packaging materials must not only be hygienic and environmentally friendly, but also have functional and high-performance packaging. This requires plastic packaging materials companies to further improve and enhance the following aspects:

The first is to innovate and develop new plastic materials and new processing technologies so that more excellent plastics can be used as packaging materials and use the high performance of new materials to achieve reduction in packaging materials.

The second is to promote the advancement and development of plastic blending technology, new plastic additives and application technology. Under the premise of ensuring non-toxic, sanitary and environmental protection of plastic packaging materials, the use of low-cost technology to improve the performance of plastic packaging materials for the reduction Offer possible.

The third is to improve and improve plastics recycling and processing technologies, so that the recycling rate of plastic packaging materials will be greatly improved, and the hidden dangers of “white pollution” caused by plastic packaging materials will be improved and eliminated, and resource utilization will be improved.

The fourth is the development of bio-based plastics, which effectively regulates the time and cycle of bio-plastics degradation. While giving full play to the function of bio-plastic packaging materials, it also reduces and eliminates the environmental pollution and impact of plastic packaging materials.

Fifth, through independent research and development and technological innovation, the cost of new plastic packaging materials and new technologies will be reduced, and the problem of too many applications for plastic materials that comply with green packaging cannot be avoided due to high costs.

Sixth, it is to develop advanced packaging technologies such as intelligentization, and to take advantage of the edible and water-soluble characteristics of some plastic packaging materials to reduce the amount of packaging waste and improve the safety and environmental performance of plastic packaging.

Similarly, plastic packaging materials are also commonly used in food packaging. In order to avoid the migration and dissolution of toxic and hazardous chemical contaminants that remain in the interior of the material and thus cause food safety accidents, plastic packaging material companies should also ensure safety.

In terms of raw material sources, biodegradable biomaterials have become a major highlight in the packaging field. Although they cannot completely replace petroleum-based plastics, the application ratio is increasing year by year under the encouragement of national policies and the promotion of enterprises. As a packaging material, especially food packaging materials, safety is the most basic principle that should be followed. How to avoid the pollution of foods caused by plasticizers, metal elements, etc. while ensuring product performance is a problem that must be solved for enterprises to survive and develop. Once again, as a part of society, enterprises must assume corresponding social responsibilities, do a good job in packaging waste disposal and resource recycling, and achieve sustainable development.

First of all, companies should strengthen self-discipline and use corresponding raw materials to produce corresponding packaging products. Food is the entrance to the food. As the last barrier to food safety, packaging is certainly not sloppy. At the same time, companies should carry out scientific and technological innovation, technological transformation and upgrading, and truly move toward green and environmental protection, not just hype the concept of green packaging.
