China's packaging industry wants to lead the industry trend
"green packaging" refers to packaging that is harmless to the ecological environment and human health, can be recycled and recycled, and can promote sustainable development. Therefore, developed countries in the world have determined that the packaging should comply with the "4R + 1D" principle, that is, low consumption, development of new green materials, reuse, recycling and degradability. In the next 10 years, "green products" will dominate the world market. "Green products" undoubtedly need "green packaging"
at present, the research and development of "green packaging" in China's packaging industry should strengthen the following aspects:
first, speed up technological innovation and develop new packaging materials, new processes and new products, which is also the key to the development of "green packaging". For example, nowadays, a large number of grains are packed in plastic woven bags. This is a kind of polymer material with high strength, low cost and corrosion resistance, but it contains a small amount of additives harmful to human body. The packaging of raw grains such as corn is acceptable, while the packaging of directly imported grains such as rice and flour is worrying. Moreover, the permeability of plastic woven bags is poor, the grain is easy to deteriorate, and it is not suitable for long-term storage. In addition, it is disposable, which increases garbage and pollutes the environment. Therefore, grain packaging must develop more scientific new packaging materials to replace plastic woven bags
Second, we should research and develop diversified "green packaging". When it comes to "green packaging", manufacturers tend to focus on easy to handle paper materials under different control measures, but in fact, from the perspective of the whole production process. Paper packaging is not "green packaging" in the full sense, because the paper industry has heavy environmental pollution, and although the paper can be recycled, the recycled paper made by each recycling will reduce the quality level of the paper. In this regard, according to the human body's preference and dislike for smell, this assessment is not as good as aluminum foil to achieve complete recycling. The packaging function of plastic, which is widely used now, can not be replaced by other materials for the time being. As long as we overcome the non degradable technical difficulties, it may become the most important green material in the new century. Therefore, "green packaging" refers not only to paper, but also degradable plastic and aluminum packaging
Third, we must establish and improve China's environmental labeling system in strict accordance with international practices and carry out certification from a high starting point. Many developed countries have taken positive measures in environmental protection packaging, such as legislating that beer, soft drinks and mineral water must use recyclable containers; Enact laws to enforce the recycling or utilization of packaging. In 1998, China promulgated the interim management measures for the recycling of packaging resources, which stipulates the treatment of waste, but it is far from enough to narrow the gap with the standards of the international community
