Recycle the new direction of the packaging industry

Food packaging is related to food safety and people ’s health. On June 1, 2009, the Food Safety Law of the People ’s Republic of China was formally implemented. It is worth noting that food packaging is included in the scope of food safety. The safety of packaging is determined in the form of law. Although China has already established hygienic standards for food packaging, the safety of food packaging has not always attracted widespread attention in the whole society. In recent years, with the improvement of consumer safety awareness and the strengthening of national supervision, food packaging has been gradually raised to the same level as food safety.

Consumers lack understanding of food packaging In terms of consumer awareness, domestic consumers pay more attention to the food itself, focusing on shelf life, food labeling, etc., and lack understanding of the safety of food packaging. Foreign consumers have a strong sense of safety, they will consciously purchase food packaging products with food safety labels, and use them strictly in accordance with the warnings on the packaging products; when problems are found in food packaging, consumers usually still Actively contact manufacturers or local regulatory authorities for enquiries, doubts and even complaints, and even use legal means to protect their own interests.

In addition, with the development of society, people have gradually shifted from focusing on quality and safety to focusing on low-carbon environmental protection. With the global low-carbon wave, low-carbon food packaging is also imperative. On April 1 this year, China implemented the "Restrictions on Commodity Excessive Packaging Requirements," and combined with China's national conditions, mandatory regulations were made on the three perspectives of food and cosmetics: void ratio, packaging layers, and cost. This move is a big step for China in the field of food packaging, but there is still a big gap for food packaging to truly become the first line of defense for human safety.

The packaging industry has entered a new stage. Food packaging is only an important part of the entire packaging industry. All along, China's packaging industry has been in development and transformation and upgrading, and has made great progress. In the first 10 years, we have gone through a period of scale expansion and variety expansion. The size and GDP of enterprises in our industry have increased, and the process from scratch has been completed for many types and products, that is, from "can't do", "can't do" to "can do", "can do". 2012 was a watershed for the development of the packaging industry. The rapid growth of more than 10 years in a row has made China's packaging manufacturing industry stand at the high level of the global manufacturing power. However, with the global financial crisis and the slowdown of China's macroeconomic growth, this continuous supply shortage in the market for many years will no longer exist.

At present, there are three unreasonable points in the domestic packaging industry: first, the product structure is mainly simple and original products, the product replacement is slow, the product structure is irrational, and it cannot fully adapt to the changes in market demand; second, the overall size of the packaging enterprise The industry concentration is relatively low; the third is the uneven development of various regions, the packaging industry in the western region is relatively backward, and the eastern region is more developed.

Considering multiple factors such as the future packaging machinery will cooperate with industrial automation and promote the general trend of improving the overall level of packaging, the future of the packaging industry is still optimistic. It is estimated that by 2015, China's paper packaging products are expected to reach 36 million tons, plastic packaging products 9.46 million tons, metal packaging products 4.91 million tons, glass packaging products 15.5 million tons, packaging machinery 1.2 million sets, the overall level of packaging industry informatization is expected Meet or exceed the moderately developed countries.

Waste treatment draws attention. With the increase in the number of packaging waste, the cost of waste disposal continues to rise. Increasing the recycling of packaging waste is the general trend. However, in the process of rapid development of packaging production, China still has a big gap with developed countries in waste management, disposal and recycling.

First, the recycling of packaging materials has obvious economic and ecological benefits. According to relevant experts, although there are many types of packaging waste, according to the material of packaging products, they can be basically divided into four categories: paper products, plastic products, glass products and metal products. Packaging waste is mostly renewable resources.

Secondly, the continuous increase in the output of packaging waste provides sufficient production resources for recycling. At present, paper packaging products are about 8.35 million tons, plastic packaging products are about 2.44 million tons, glass packaging products are about 4.44 million tons, and metal packaging products are about 1.61 million tons. At the same time, these products are growing at a rate ranging from 12.5% ​​to 30% every year. Research data show that 1 ton of waste paper can be recycled with 0.8 tons of new paper or 0.83 tons of cardboard; 1 ton of waste plastic can be recycled with 0.75 tons of diesel or 0.6 tons of unleaded gasoline. It can be seen that the problem of recycling "raw materials" need not be worried at all.

Thirdly, the treatment technology for packaging waste is becoming more and more mature. The processed packaging waste has a wide range of uses and a promising market prospect. After recycling, the discarded fast food boxes can be mixed with soil or other substrates through shredding and harmless treatment for soilless or semi-soil cultivation. The waste plastic oil technology uses high-performance catalysts to "depolymerize" high-density polyethylene or polypropylene plastics to produce diesel and gasoline that meet national standards, with an oil production rate of more than 75%. If necessary equipment is installed, liquefied gas and carbon black can also be recovered. By changing the catalyst, it can produce chemical products such as toluene, xylene and pure benzene. In addition, waste plastic and filling mixture are used to form a fertilizer coating, and the cost of the coating is only about 300 yuan / ton higher than that of ordinary compound fertilizers. This is an environmental protection project that changes "white pollution" into "green fertilizer", which can absorb a large amount of packaging waste.

We have reason to believe that if a lunch box can become a porter of safe food, efficiently complete its mission, and then return to nature environmentally, or regenerate into new environmentally friendly materials, it will be the development of the packaging industry that everyone is willing to see direction.
