Competing in the field of food packaging, paper packaging will be better than plastic packaging

at present, there are many kinds of food packaging in the market, including paper packaging, plastic packaging, metal packaging and glass packaging. Who can become the protagonist of the market? Interviewed Qian Jin, Secretary General of China Packaging Technology Association

Secretary General Qian said that in the modern packaging industry system, ② a kind of experimental machine paper and paper containers occupy a very important position. In China, paper packaging materials account for about 40% of the total packaging materials. From the perspective of development trend, the consumption of paper packaging will be increasing. The reason why paper packaging materials take the lead in the packaging field is that they have a series of unique advantages, such as good processing performance, excellent printing performance, easy composite processing, wide sources of raw materials, easy to form mass production, diverse varieties, low cost, light weight, easy transportation, recyclable waste, etc. The use of plastics as packaging materials is an important symbol of the development of modern technology, and the source of raw materials is rich. However, plastic packaging materials used in food packaging have obvious shortcomings, and there are some health and safety problems and environmental pollution problems caused by packaging waste

Secretary General Qian said that the amount of plastic used for food packaging accounted for 1/4 of the total plastic output. It can be said that as soon as plastics used for food packaging appear, garbage will be generated. In supermarkets and shopping malls, many food packages are made of plastic. The plastic inflatable packaging of puffed food can prevent moisture, oxidation, fragrance, sunlight and extrusion, but such a large packaging is a great waste of resources. In terms of instant noodles packaging, plastic packaging is far more than paper bowl (or barrel) packaging. The selling price of bowl or barrel instant noodles in the market is generally 1/3 higher than that of bagged instant noodles of the same quality. However, this packaging method is convenient to eat, especially when the eldest son and daughter-in-law are divorced and travel, they can be eaten directly with hot water after opening the cover, (2) what is type approval and type evaluation without bringing other containers, so it is very popular with consumers

with the improvement of environmental protection requirements, it is necessary for consumers to eliminate backward packaging. The improvement of plastic materials is also a top priority. The food in the market segment can be packaged in paper, so as to reduce the waste of plastic and environmental pollution, which is also beneficial to future generations

Secretary General Qian said that wrapping paper is widely used in the food packaging market. He introduced a variety of new types of food packaging paper

fruit and vegetable paper is produced by Gaoqi paper company in Japan from apple pomace discarded in the food industry. The method is very simple. Remove the seeds in the fruit residue, pound it into pulp, and add an appropriate amount of wood fiber. This kind of fruit residue pulsation fatigue testing machine also has its shortcomings. Paper is easy to decompose after use, can be burned or composted, and can also be recycled for papermaking, which is not easy to pollute the environment

a Japanese Research Institute used new technology to make a kind of edible wrapping paper with certain nutritional value that melts in the presence of heat, using soybean dregs as raw materials. It is especially suitable for the packaging of fast-food noodles seasoning, and can be eaten together with the packaging

the carrot paper developed in the UK is based on carrots, added with appropriate thickeners, plasticizers and water repellents, and made of the natural color of carrots to make edible colored vegetable paper with good quality and low price. This product can be used in the individual packaging of boxed food or directly as convenient food, which can not only reduce environmental pollution, but also enhance the beauty of food and mobilize consumers' appetite. Carrot paper is a kind of edible colored paper, which has strong flexibility and certain water resistance, and has packaging and edible functions. If these products can further improve the strength and plasticity, improve the surface texture, and make products of various shapes, they can further expand their use, better protect the environment, and provide a new way for the deep processing of vegetables

foam paper was developed by a German company. Packaging materials produced with foam paper can replace foamed plastics. This kind of foam paper uses old books and newspapers and flour as raw materials. First, the recycled old books and newspapers are cut into pieces, and then ground into fibrous pulp. It is mixed with flour in the ratio of 2:1, and the mixed pulp is pressed into cylindrical particles, which can produce various shapes of packaging according to different needs. Foam paper can be formed at one time without chemical additives, and can be recycled and processed after use

an American enterprise developed paper that can convert solar energy into heat energy, which acts as a solar collector. When the food is packaged with this paper and placed in the sunshine, the food in the package will be heated. Only when the package is opened, the heat will dissipate

Secretary General Qian finally said that the world packaging paper market demand will grow at a rate of 2.8% per year. It is expected that by 2010, the market demand will reach 125 million tons, and the production will be relatively concentrated. Eastern Europe, the Middle East, Asia and Latin America are the regions with the fastest growing demand for packaging cardboard in the world

at present, Oceania is the most concentrated area of packaging board production, followed by Africa and Japan. In the next few years, the centralized situation of packaging board production will continue to develop. In the global output of packaging board, North America accounts for 39%, Western Europe 21%, Asia 28%, Latin America 6%, Eastern Europe 3%, and the rest is Africa and Oceania. In terms of production facilities, Nordic and Oceanian countries have the most modern large paperboard machines, while eastern European, Latin American and African countries retain small old-fashioned equipment. It is expected that North America and Western Europe will maintain the leading position in the production of packaging paperboard this year, and the output before 2010 will still account for 45% of the global total output, and continue to become the export region of the world's packaging paperboard
