With the advancement of human society, the development of the national economy, and the improvement of people's living standards, the market of naked foods bundled with a straw and a straw rope is gone forever; nowadays food packaging is attracting more and more people. Emphasis is placed on selling products from manufacturers to consumers choosing products as a measure of the value of goods. However, China's food packaging level is currently in its infancy, and it can be seen from the continuous growth of China's food packaging materials, especially the rapid development of chemical polymer materials. In the United States, Germany, and Italy, the annual plastics used for food packaging are 4.5 million tons, 2 million tons, and 1.9 million tons. The demand for food packaging in China is expected to reach 1.5–2 million tons this year.
The modern food industry needs scientific food packaging. Although packaging research and new materials development in China have been relatively rapid in the past 20 years, packaging engineering is an emerging edge discipline, involving a wide range of knowledge, coupled with packaging research and packaging industry. Late in the beginning, China's packaging technology is still relatively backward, and can not fully meet the requirements of the fast-growing food industry. In particular, people's ideas are still relatively old, and inadequate packaging and over-packaging are common.
As a good package, it must have several functions: (1) to ensure that the product is in the best condition; (2) the product is not affected by the outside world (such as light, odor, microorganisms, etc.); (3) in consumption, Carrying, opening, warehousing, transportation and other links bring the greatest convenience.
First, the food packaging is worth noting
Packaging should pay attention to miniaturization and de-zeroing. In Hangzhou, the roasted seeds and nuts industry circulated the story of a small walnut “a hammer of 30 million yuan”. Traditional small walnuts are time-consuming and labor-intensive. After the shells are made into small packages, the sales of Hangzhou walnuts increase by 30 million yuan a year. The old-fashioned beans of Shanghai Old Town Temple are still old faces, which girl will hold A large bag of spiced beans on the street? Starch packaging, not 250 grams, is 500 grams, why not make a small package of 10 grams, 20 grams per package, can be used up once and twice?
Product packaging design needs to be injected into the cultural concept. The “Shanghai Old Wine” of the Chinese brewing factory changed its old face, using the Shikumen pattern rich in Shanghai's humanistic characteristics as the outer packaging design, and it was a hit; Shanghai branded a box of chocolates, each of which printed different Shanghai attractions. Become a popular tourist commodity. And there are some food packaging designs, people are clouds, or too realistic, rough, or a universal beauty, how can you quickly capture the hearts of customers?
The concept of moderate packaging and environmentally friendly packaging needs to be strengthened. The health care product packaging has three layers and three outer layers. The moon cake packaging box is luxurious and exquisite year after year, and the over-packaging phenomenon is still serious. Many "green food" packaging also uses non-degradable plastic products. Mooncake packaging boxes have been popular in medium-density plate packaging since last year. Experts pointed out that MDF contains formaldehyde. The harm of formaldehyde to human body is well known. Is this material environmentally friendly? After joining the WTO, enterprises in this city must understand the product packaging from the height of “green barriers”, otherwise the consequences will be unimaginable.
Second, the future direction of China's food packaging development
In the next few years, the development of China's food and beverage packaging will be the most obvious, and its importance is arranged in order as follows:
(1) For most new types of packaging, raw materials based on petrochemical products are mainly used.
(2) Further development of aseptic packaging will reduce the need for refrigeration equipment. Some consumers believe that metal canned foods are high-end products, aseptic packaging is mostly cartons and low prices are considered low-end products. In fact, this is a misunderstanding. Packaging should be done with less effort. As long as the food can be best preserved, the cheaper it is, the better the packaging.
(3) More and more people willing to use plastic cans and plastic bottles, which will replace glass products and, in some cases, metal products.
(4) Flexible packaging materials are developing to high quality. The introduction and development of flexographic printing in China began in the 1970s. Now we are able to manufacture our own flexographic printing presses and their substrates, as well as a variety of flexible printing inks. In particular, the regular production of water-based inks and water-based glazing agents can be applied to other types of inks to cover the water glazing, to cover the volatilization of the remaining toxic solvents; and to directly contact the food to ensure food safety and hygiene. In addition, he has accumulated rich experience in the printing process, and has been able to print printed products not lower than traditional crafts, such as in internationally renowned brands such as “Coca-Cola” and “Pepsi-Cola”, reaching international standards and international Close horizontally.
In China, flexographic packaging printing has made great progress in the past 10 years, but the development momentum is not fast. From the perspective of packaging and printing practitioners, we should boldly innovate from machines, materials and processes, actively explore and climb the peak. Only by taking the first-class products can we get the welcome of the manufacturers and the love of the customers. For the operators of the majority of food companies, they also hope to emancipate their minds and let go of new packaging. For example, there are some flexographic prints that are not as good as traditional prints. Can you adapt to the improved packaging design? Another example is that the color of the flexographic printing is not bright enough, but it is particularly thick, and it can fully enhance the short-sightedness and achieve better visual effects.
(5) Reducing the cost of packaging by improving the performance of packaging materials, rather than unilaterally pursuing the reduction of material prices. Packages are different from general products (general products are usually only used in one specific occasion), requiring frequent loading, encapsulation and storage. , transportation and other commodity processes, customers often have a process of storage and use after buying, so we must ensure and improve the quality of packaging.
(6) Lightweight packaging will continue to make progress. The general trend of reducing the quality of packaging is also clearly seen from some of the above projects. By replacing the glass and metal containers with smaller flexible packaging and plastic cans and plastic bottles, transportation costs can be reduced in size. Its development trends include: easy to pick up and carry, need to stock, due to the lighter packaging, the corresponding load on the tray is reduced, you can reduce the spleen and lift forklift; used to put a single carton, glass and plastic containers and flexible packaging Packaging that is packaged in food packaging needs to be increased in intensity for safe transportation to the store.
(7) Traditional fiber packaging materials (cellophane and translucent paper) are gradually being phased out. The most likely replacement for cellophane is the polypropylene film. Translucent paper (and grease-proof paper) will be replaced by high-density and low-density metal foils, especially those with bimetallic extrusion and resin addition.
(8) Packing and packaging is promoted in the food and beverage market.
Third, the food industry development needs for the packaging industry
There are many industries associated with the food industry, especially in the packaging industry. Food industry products need packaging, and the quality of packaging directly affects the quality, grade and market sales of food industry products. Although food packaging does not represent the intrinsic quality of food, good packaging can guarantee and extend the life of food quality, extend the shelf life of food, and excellent packaging can earn a reputation for products and give consumers priority. Therefore, food companies attach great importance to the packaging options of products, including the design and selection of filling, packaging machinery and packaging materials, packaging and decoration.
The products of various industries in the food industry have experienced a large increase in the “10th Five-Year Plan”. The products of various industries have different packaging machinery, packaging materials, packaging forms and scales. The growth rate of products according to the industry can be measured, and the main products are packaged. Demand has a 10-20% increase, or even more. Of course, the quality of packaging needs to be further improved. Taking beer as an example, it increased by 16.8% in five years and by 51% in 2015 compared with 2000. Therefore, the packaging materials for beer, bottles, cans and barrels should be increased accordingly. This is the development of the food industry for the packaging industry. The amount of demand.
There are many food industry industries, and the packaging demand of corresponding products has formed a certain pattern. The corresponding packaging enterprises should propose corresponding development countermeasures through market research, including packaging machinery, packaging materials, packaging specifications, etc., on the basis of the present, There have been new developments during the 10th Five-Year Plan period. Here I propose several industries with great development potential. First, convenience foods, convenience foods are a broad concept, and their products are subordinated to various industries in the food industry. The development speed is quite fast, the potential demand is large, and their varieties are diverse. The form and specifications are different. The demand for the packaging industry is undoubtedly new and largest. Second, dairy products, which have a large potential demand, are the industries in which the food industry is developing rapidly, but the dairy products are single and cannot be Adapting to the needs of market changes, especially the supply of liquid milk in cities, the annual plan for the “10th Five-Year Plan” period is increased by 15%, reaching 2 million tons, which has great potential for packaging; the third is the processing of agricultural and sideline products, and now many regions are accelerating agricultural products. Fresh processing strength. We have commended more than 40 food industry-strength counties this year. The output value of the food industry in these counties is 40-60% of the county's industrial output value. A number of leading food enterprises have emerged, but these products are generally backward in product packaging, according to my arrival in some counties. Enterprises visit to understand that these companies' products are first-class quality, second-rate packaging, and the packaging industry is promising for the development of township food enterprises.
With the further adjustment of the product structure of the food industry and the upgrading and upgrading of products, new requirements are also placed on packaging. First, food quality and safety assurance, stricter requirements on packaging technology and packaging materials; second, filling and packaging forms and Speed and specifications are more diversified, and strive to standardize, serialize and generalize packaging materials and containers; third, higher requirements for packaging decoration and packaging image; fourth, new breakthroughs in packaging anti-counterfeiting; Packaging costs. Due to the different products in various industries of the food industry, the above requirements are emphasized. For example, milk, meat, processed aquatic products, and fruit and vegetable products have stricter requirements on preservation and quality. Confectionery requires more diverse packaging machinery and packaging specifications. Packaging, packaging requirements are higher; and some high-end foods and a large number of products have higher requirements for anti-counterfeiting identification.
As early as 1984, the "Outline of the National Food Industry Development 1981-2000" approved by the State Council pointed out that the food industry has many industries and covers a wide range, and is closely related to many other sectors of the national economy. It is mentioned that the development of the food industry has a positive effect on the packaging (industrial) sector. I personally understand that the development of the packaging industry requires the development of the food industry to drive the development of the food industry requires the development of the packaging industry to give strong support, the food industry, packaging industry should strengthen cooperation, common development, and make greater development of the national economy.
