Food packaging can not be separated from the safe wedding dress

In the National Food Safety Promotion Week in 2013, a sub-forum on "Safe Control and Recycling of Food Packaging Materials" was established. This is because last year, the issue of food packaging became the focus. Someone is hyping, some explain it, and it is stirring up. Experts expressed their opinions and opinions on this.

Li Peisheng, the honorary director of the Green Packing Committee of the Chinese Society of Environmental Sciences, interprets: “Food is like a bride who is about to marry, and food packaging is the bride's beautiful fit and safe wedding dress.”

Shanghai "3 cents project" explores a new path for the control of white pollution

In recent years, some people have given a lot of unreal to disposable foam boxes. Although the 21st order has now been promulgated, many ordinary people still find it difficult to understand. The most typical is that some people say that once the disposable foam box is heated to 65°C, it will produce dioxin-like carcinogens, which will release poison when used. In fact, there are three conditions for the production of dioxins: the presence of a benzene ring, the presence of atoms of bromine and chlorine, and chemical changes that must occur between 270°C and 400°C. The three are indispensable to produce dioxins and cause cancer in the human body.

Li Peisheng stressed that it should be stated that the disposable foaming food boxes do not cause pollution because the polystyrene raw materials are non-toxic and harmless. The fundamental cause of white pollution is caused by the bad habits of discarding wastes at random and the mismanagement by governments at all levels, not the products themselves.

He said that 12 years ago, Shanghai implemented the “3-point project” and it worked well. Before they issued this document, they spent a year and a half investigating. The measure is that for disposable cutlery, the person who produces it will pay 3 cents in accordance with the principle of international governance, and then distributes the food container, and 5 cents for transportation and recycling companies, which has achieved great results in 12 years. Achievements. This has created a path for the global governance of white pollution and the implementation of circular economy for commodity packaging.

After using fresh-keeping film, the freshness of cucumber is increased from 3 days to 14 days.

The safety of plastic packaging for food is a topic that people are concerned about in recent years. In this regard, Senior Engineer Tang Saichen of the China Light Industry Information Center said that plastic packaging materials are playing an increasingly important role in ensuring the safety of food packaging.

She explained that the current plastic packaging materials used for food, the main component is based on hydrocarbon materials, as long as the standard strict control of the amount of additives, follow the correct principles of use, the health of plastic packaging materials can be guaranteed No harm to human health. However, if the supervision of processing is not strict and it is not done according to standards, shoddy products may also produce some harmful and toxic substances, which will have a non-negligible impact on food safety. We must attach great importance to this and be vigilant.

There are many factors in life that endanger food hygiene and safety. Among them, food is in the sales cycle. Due to the lack of better packaging materials, refrigeration technology and preservation technology, mildew rot is one of the most serious factors. According to reports, developing countries have lost more than 50% of their total food production each year. About 30% of China's food and fruits are sold out every year due to decay and deterioration. In the 1990s, as plastics were light, highly transparent, easy to process, and had good hygienic safety, they quickly entered the packaging field and gained rapid development. It is understood that the current total consumption of food packaging market, the amount of plastic packaging has exceeded the sum of the amount of traditional packaging materials such as paper, metal, has exceeded 50%.

Among them, with the development of plastic packaging, functional packaging speed has also been applied. For example, fresh-keeping packaging of cakes and other foods greatly reduces the loss and waste caused by mildew, rot, deterioration, etc., and has a great significance in terms of shelf life.

Practice has proved that cucumber can be extended from 3 days to 14 days after using cling film. The packaging of moon cakes used to be preservatives with the maximum limit allowed by the license. The shelf life is only about one week. With the use of highly transparent films, the moon cake's shelf life is improved to more than two months, and some of them can even be achieved. Six months.

Modern commodity circulation and sales methods, such as refrigeration, logistics, and supermarkets, are inseparable from plastic packaging materials, which can protect foods, improve food hygiene and safety, and reduce waste and loss. It has become a must to ensure food safety. Less important materials, and play an increasingly important role in the development of human society and civilized life.

There are many legal requirements for food packaging materials. Food safety requires industry self-regulation

According to Professor Wang Zhutian from the National Food Safety Risk Assessment Center, food safety assessment is extremely complicated on the packaging. It is definitely not eaten during the meal, but people are so interested and valued. Because the material that stays on the packaging material is transferred to the food through the medium, this migration is also affected by the time, temperature, and the medium of the packaging material. It has a great influence on the whole food and is the most complex in the whole food safety risk assessment. One of the categories is also the most spent one.

In terms of legislation, China calls packaging materials called packaging materials. In some countries in Europe and America, it is basically called food contact materials. It is more in line with the requirements of packaging material properties. In our country’s food safety law, there are basically 20 national standards for 8 items, which are food-related products. They are described as used for food packaging materials, containers, detergents, or for food production and operation. Tool equipment.

There are many requirements in the country of food packaging materials. Through the legal system, two lines can be teased out. Some of them are represented by food safety standards, and some are reflected by departmental regulations. In addition, there are some department regulations, and the Health and Family Planning Commission has also issued a license for a certain product in the form of an announcement.

The issues involved in the study of packaging material safety standards, whether it is the European Union, the United States, or Japan, are a benchmark for our system in food standards, and these three are completely different for the management of packaging materials, so how do we say in our country? Doing our own standard package system requires careful study.

Ms. Zhao Yali, chairman of the China Beverage Industry Association, stressed that food safety requires more self-discipline in the industry. In 2008, packaged drinking water introduced an industry-wide self-discipline convention that includes quality control, market environment, and protection of water sources. Lax supervision, incorrect and unscientific use are the major causes of safety problems, and have nothing to do with the material of the plastic packaging material itself. These problems also appear for other materials of packaging materials, and there are many similar cases. How to make the public understand and recognize the science of plastics, let the public make good use of plastics, and let plastic packaging truly become an important part of the public's mind to ensure food safety and life. It is the duty of the scientific and technical workers to take responsibility. Text / commoner
