The hottest new trend of food packaging developmen

  • Detail

With the progress of human society, the development of national economy and the improvement of people's living standards, the naked food market, which is bundled with several hairtail and a straw rope, has gone forever; Nowadays, people pay more and more attention to food packaging. From manufacturers promoting their products to consumers choosing goods, they all take it as a measure of the value of goods. However, the level of food packaging in China is currently in its infancy, which can be seen from the continuous growth of food packaging materials in China, especially the rapid development of chemical polymer materials. The annual plastic used for food packaging in the United States, Germany and Italy is divided into 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

modern food industry needs scientific food packaging. Although China will eventually accelerate the decay rate of material toughness in the past 20 years, packaging research and new material development are relatively rapid, because packaging engineering is a new frontier discipline, involving a wide range of knowledge, coupled with the late start of packaging research and packaging industry, China's packaging technology is still relatively backward in general, and can not fully meet the requirements of the rapidly developing food industry. In particular, people's ideas are still relatively old, and the phenomenon of insufficient and excessive packaging is widespread

as a good package, it must have the following functions: (1) ensure that the product is in the best state; (2) The product is not affected by the outside world (such as light, odor, microorganisms, etc.); (3) Bring the greatest convenience in consumption, carrying, opening, storage, transportation and other links

I. food packaging should be noted

packaging should pay attention to miniaturization and fragmentation. In Hangzhou, there is a story about small walnuts hitting 30million yuan with one hammer in the speculation industry. The traditional small walnuts are time-consuming and laborious to eat. After shelling and leaving meat to make small packages, the annual sales of small walnuts in Hangzhou will increase by 30million yuan; The spiced beans in the Old City God Temple in Shanghai have been packaged for many years. Which girl will chew on the street with a large bag of spiced beans? Starch packaging is either 250 grams or 500 grams. Why not make it into small packages of about 10 grams or 20 grams each, which can be used up twice at a time

product packaging design needs to inject cultural ideas. The Shanghai old wine of China's breweries changed its old face and adopted the Shikumen pattern rich in Shanghai's cultural characteristics as the outer packaging design, which made a hit; A brand of boxed chocolates made in Shanghai, each of which is printed with different places of interest in Shanghai, has become a popular tourist commodity. However, the packaging design of some foods is echoed by others. Either it is too realistic and crude, or it is universally applicable. How can it quickly grab the hearts of customers

the concept of appropriate and environmentally friendly packaging needs to be strengthened. There are three layers inside and outside the package of health products, and the packaging box of moon cakes is more luxurious and exquisite year by year. The phenomenon of over packaging is still serious. Many green food packages actually use non degradable plastic products. Moon cake packaging boxes have been popular since last year. Experts pointed out that MDF contains formaldehyde. The harm of formaldehyde to human body has been well known. Is such a material environmentally friendly? After joining the WTO, enterprises in this city must understand product packaging from the height of green barriers, otherwise the consequences will be unimaginable

II. The development direction of food packaging in China in the future

in the next few years, the development of food and beverage packaging in China will be the most obvious, and its importance is listed as follows:

(I) for most new packaging, raw materials based on petrochemical products are mainly used

(II). The further development of sterile packaging will reduce the need for refrigeration equipment. Some consumers believe that metal canned food is a high-end product, and aseptic packaging is mostly cartons with low prices, which is considered to be a low-end product. In fact, this is a misunderstanding. Packaging should get twice the result with half the effort. As long as food can be best preserved, the more this will also provide inexhaustible development power for the extruder industry. Cheap is the more superior packaging

(III). More and more people are willing to use plastic cans and bottles, which will replace glass products and, in some cases, metal products

(IV). Flexible packaging materials are developing towards high quality. The introduction and development of flexographic printing in China began in the 1970s. Now we have been able to manufacture flexographic printing machines and their substrates, as well as various flexible printing inks. In particular, the standardized production of water-based inks and water-based polishes can add a set of one color water-based polishes on other types of inks to cover the volatilization of other toxic solvents; It can also be in direct contact with food, ensuring food safety and hygiene. In addition, he has also accumulated rich experience in printing technology, and has been able to print prints that are not lower than the traditional technology. For example, in the label printing of international well-known brands such as Coca Cola and Pepsi Cola, it has reached the international level and approached the international level

in China, flexographic packaging printing has made great progress in the past 10 years, but its development momentum is not fast. From the perspective of packaging and printing practitioners, we should make bold innovations in machines, materials and processes, actively explore and climb the peak. Only with first-class products can we win the welcome of manufacturers and customers. For the majority of food business operators, we also hope to emancipate our minds and let go of the use of new packaging. For example, flexographic printing is indeed less exquisite than traditional printing. Can we adapt to it by improving the design of packaging? Another example is that the color of flexographic printing is not bright enough, but it is particularly thick, which can fully develop strengths and circumvent weaknesses, and achieve better visual effects

(V). Reduce the packaging cost by improving the performance of packaging materials, rather than unilaterally pursuing the reduction of material prices. Packaging is different from general products (general products are usually used only on a specific occasion), and it requires frequent loading, packaging, storage, transportation and other commodity processes. Customers often have a process of storage and use after buying, so the packaging quality must be guaranteed and improved

(VI). Light packaging will continue to make progress. The general trend of reducing packaging quality can also be clearly seen from some of the above projects. Replacing glass and metal containers with flexible packaging, plastic cans and plastic bottles with smaller weight can greatly reduce transportation costs. Its development trends include: it is easy to pick up and carry goods, and those who need inventory can reduce the pallet load correspondingly due to the lighter packaging, which can reduce the number of pallets and forklifts; The packaging used to pack individual cartons, glass and plastic containers, flexible packaging and other food packaging needs to increase its strength to facilitate safe transportation to stores

(VII). Traditional fiber packaging materials (cellophane and translucent paper) have a trend of being phased out. Polypropylene film is most likely to completely replace cellophane. Translucent paper (and grease proof paper) will be replaced by high-density and low-density metal foil, especially those with bimetal extrusion and resin, which can double their functions

(VIII). Packing in the food and beverage market, Ganfeng lithium industry is carrying out the recycling of lithium containing wastewater at the same time and has been promoted

third, the demand of the development of the food industry for the packaging industry

there are many industries related to the food industry, especially the packaging industry. Food industrial products need packaging, and the quality of packaging directly affects the quality, grade and market sales of food industrial products. Although food packaging cannot represent the internal quality of food, good packaging can ensure and prolong the life of food quality and prolong the shelf life of food. Excellent packaging can win the reputation of establishing a comprehensive strategic partnership with Shandong South University for products and give consumers the first choice. Therefore, food enterprises attach great importance to the packaging selection of products, including the design and selection of filling, packaging machinery, packaging materials and packaging decoration

the products of all industries in the food industry have increased significantly in the tenth five year plan. The products of all industries have different packaging machinery, packaging materials, packaging forms and scales. According to the growth rate of industrial products, the demand for packaging of major products has a% growth rate, or even more. Of course, the packaging quality needs to be further improved. Take beer for example, it has increased by 16.8% in five years and 51% in 2015 compared with 2000. Therefore, the packaging materials such as beer filling equipment, bottles, cans and barrels should be increased accordingly, which is the demand of the development of food industry for the total amount of packaging industry

there are many food industry industries, and the packaging demand of corresponding products has formed a certain pattern. The corresponding packaging enterprises should put forward corresponding development countermeasures through market research, including packaging machinery, packaging materials, packaging specifications and so on. On the current basis, there should be new development during the Tenth Five period. Here I propose several industries with great development potential. First, convenience food is a broad concept. Its products belong to various industries of the food industry, with a rapid development speed and a large potential demand. Its varieties are diverse, and its forms and specifications are different. The demand for the packaging industry is undoubtedly new and the largest; Second, dairy products have a large potential demand, which is an industry with rapid development of the food industry at present. However, the packaging of dairy products is single, which can not meet the needs of market changes, especially the supply of liquid milk to cities. During the Tenth Five Year Plan period, the average annual increase is 15%, reaching 2million tons, and there is a great potential demand for packaging; Third, agricultural and sideline products processing products. Now many regions are accelerating the fresh-keeping processing of agricultural products. This year, we commended more than 40 strong counties in the food industry. The output value of the food industry in these counties is% of the industrial output value of the county, and a number of leading food enterprises have emerged. However, the product packaging of these enterprises is generally backward. According to my visit to some county enterprises, the products of these enterprises are first-class quality and second-class packaging, and the development of the packaging industry to Township food enterprises is promising

with the further adjustment of the product structure and the upgrading of products in the food industry, new requirements are also put forward for packaging. First, food quality and safety assurance, with stricter requirements for packaging technology and packaging materials; Second, the filling and packaging forms, speeds and specifications are more diversified, and the packaging materials and containers are standardized, serialized and generalized; Third, higher requirements for packaging decoration and packaging image; Fourth, new breakthroughs should be made in the anti-counterfeiting of packaging; Fifth, try to reduce packaging costs. Due to the different products in various industries of the food industry, the above requirements are emphasized, such as milk, meat, processed aquatic products, fruit and vegetable products, which have stricter requirements for fresh-keeping and quality assurance; candy has more diversified requirements for packaging machinery and packaging specifications, and higher requirements for packaging decoration; However, some high-end foods and single products with large quantities have higher requirements for anti-counterfeiting identification

as early as 1984, in the "1981-2000 national food industry development outline" approved by the State Council, it was pointed out that the food industry has many industries, covers a wide range, and is closely related to many other departments of the national economy. It is mentioned that the development of food industry can promote the packaging (industry) sector. My personal understanding is that the development of the packaging industry needs to be driven by the development of the food industry, and the development of the food industry needs to be vigorously promoted by the development of the packaging industry
