Technology and environment of food packaging

food packaging is the application field that makes the greatest contribution to the packaging industry. The output value of the food packaging industry accounts for more than 60% of the total output value of the packaging industry, which is compatible with the status of the food industry itself

China's food industry includes many market segments, such as beverages, dairy products, wine and alcoholic beverages, edible oil, candy, convenience foods, condiments and so on. Among them, beverages, dairy products and beer are the industries with the largest demand for single packaging products such as PET bottles, two-piece cans and paper composite sterile packaging

the improvement and development of food packaging, on the one hand, depends on the progress of packaging technology itself, on the other hand, has a great relationship with the change of product sales environment and conditions, as well as the change of people's living standards and habits. Every successful food packaging is a perfect combination of the three

the noise and agitation of dairy packaging

Tetra Pak is the largest packaging enterprise in the world and the most successful foreign-funded packaging enterprise in the Chinese market. Some people even say that Tetra Pak's ultra-high temperature sterilization technology and sterile packaging have created today's prosperous liquid milk market and dairy industry pattern in China

to be fair, this statement is not very exaggerated

as China's milk sources are far away from central cities, before a complete cold chain is formed, it is difficult for dairy enterprises to have a sales radius of more than 500 kilometers, especially for liquid dairy enterprises. Tetra Pak aseptic packaging technology has extended the shelf life of liquid dairy products to more than one year, so it has become a prerequisite for the expansion of Chinese dairy enterprises

it is also Tetra Pak, which is powerful in the Chinese market, but it is difficult to do anything in the American market. On the one hand, there is Tetra Pak's strong competitor international paper in the U.S. market, but more importantly, the United States has already formed a perfect cold chain system. In this environment, the U.S. market has been completely occupied by pasteurized milk

therefore, it is not difficult to understand why, with the improvement of China's cold chain, dairy packaging enterprises led by international paper industry have launched a Jedi counterattack against pasteurized milk in the Chinese market

whether Tetra Pak or international paper industry, at present, China's dairy packaging market is dominated by paper composite packaging, which makes the product packaging in China's dairy market uniform, lack of personality, and it is difficult for manufacturers to carry out differentiated management. Therefore, looking for other dairy packaging forms has always been the passion of enterprises. At present, although there are still composite paper or plastic soft packaging such as Baile bags and Tetra Pak pillows in the Chinese market, they still can't bloom like beverage packaging

the technology of HDPE bottle used for normal temperature milk packaging has matured, and may become the next hot spot of dairy packaging. At present, the main reason why enterprises are still waiting is the huge investment. However, compared with normal temperature milk packaging, it is easier to diversify dairy packaging. It will be a new packaging system developed by relying on the cold chain

consumption habits and packaging of meat products

cooked meat products processed on site in the Chinese market have become less and less, and many cities have required cooked 70 meat products processed in supermarkets to be packaged and sold

packaging is the requirement of industrialized food production. Only with good packaging can food enterprises expand their sales radius and better establish their brands. Today, Chinese consumers have fully recognized the packaged cooked meat products, because the sales of these products are mainly completed in supermarkets

raw meat in European and American countries is also basically sold in supermarkets or food malls. Even if overseas Chinese are used to buying in the vegetable market, the proportion of raw meat without packaging is also very low. This is very different from the current situation in China. At present, the proportion of raw meat packaging in China is very low. Even residents in big cities mainly purchase raw meat in the fresh market, and the packaging of raw meat is not accepted by most consumers. This is related to the consumption habits of Chinese people and the misunderstanding of meat nutrition. Chinese people have not widely accepted the view that pre cooled raw meat is more nutritious and has better taste. Most people still habitually believe that the meat closer to the slaughter time is the better

for a long time, the reasons for the slow development of raw meat packaging in China are consumption habits and cognitive bias, and the limitations of consumption level. With the improvement of Chinese residents' consumption level, higher requirements for nutrition and sanitation, and the impact of large-scale shopping malls on urban residents' consumption habits, China's raw meat packaging is beginning to accelerate its development. Just like the cooked meat packaging in the past, once it is accepted by the market, it is likely to expand rapidly in a very short time, at a speed faster than experts expect

the loss of plastic beer bottles and the pride of transparent bottle labels

the number of seminars on plastic beer bottles has decreased recently, but it does not mean that the market has fallen. On the contrary, it is the darkness before dawn

plastic beer bottles have not yet opened the market in China, mainly due to the following factors:

1. The technology itself is not qualified. Multilayer bottles have the possibility of delamination; The coating bottle has the phenomenon of coating falling off

2. the sample is not matched with the existing process when the wire is broken and cannot be energized. 4. Bag lining material the existing sterilization and filling line of the brewery cannot be directly used for plastic beer, and the line change requires a large investment

3. the cost is higher than that of glass bottles, although the cost gap is gradually narrowing

there is a demonstration effect in the promotion of products. A successful case may drive the development of an industry. Although some bottle making enterprises have been seeking cooperation with breweries, so far, there is still no breakthrough. There is a misunderstanding. In order to open up the market, the technology suppliers and bottle making enterprises of plastic beer bottles are accommodating the existing production lines of beer enterprises, always trying to make beer bottles adapt to the glass bottle production line intact, thinking that it is easy for beer enterprises to accept it, but it is not necessary to cut feet to fit shoes to obtain perfect results. Maybe change your mind to persuade the brewery to design the process route with the plastic beer bottle production line as the goal when it launches the new production line, so it is easier to obtain satisfactory results

in addition, Valet filling is becoming an emerging industry. Anxious bottle making enterprises may one day set up a plastic beer filling line to start the application market of plastic beer bottles in China. Of course, since beer production enterprises are much more complex than beverage production technology, it is only a guess whether they can do it

in contrast to the difficulty of plastic beer packaging, the rapid growth of transparent beer labels. After Jinwei beer first spent a lot of money to introduce the German transparent label labeling machine, the transparent beer label quickly spread in the high-end beer market. At present, famous brands such as Heineken and Carlsberg have begun to use this new label product to enhance the brand image

convenience food packaging should be convenient

convenience food is one of the fastest growing packaging markets, and its products mainly include instant noodles, biscuits, convenience snacks and so on. Due to the wide variety, the packaging is also very different. The first thing to pay attention to in the packaging of convenience food is to provide the best convenience

many convenience foods are packaged in plastic bags in the form of disposable consumption. Most of these products are carved with a triangular notch on one side of the bag, which is convenient for consumers to tear open the package; Aluminum plastic composite plastic bags are generally cut into a row of sharp corners at the sealing edge of the bag. This kind of packaging has a common problem, that is, it is difficult to tear out the neat opening, and the tear often presents an irregular shape, causing the contents to fall. The latest technology is to use a laser scoring machine to carve a shallow scratch on the top of the bag, so that consumers can tear out a neat opening every time. It is believed that this technology will soon be popularized in the domestic food industry

there are many problems in the new urbanization standard system of convenience food bags that need to be eaten many times, including green building materials, relevant standards for municipal infrastructure construction and relevant standards for strategic emerging industries. Zipper bags, which are widely used abroad, are not widely used in domestic convenience food packaging. The combination of plastic "pull lock" and laser scoring technology will provide real convenience for convenience foods that need to be resealed and packaged

the diversity of food packaging provides a broad space for food packaging designers to imagine and experiment. Food design is getting rid of a single graphic design mode, and paying more attention to function and structure, safety and health, and in-depth understanding of consumption habits

food packaging has gradually evolved from individual behavior to collective behavior. This group includes not only food engineers, packaging engineers and marketing personnel from within the enterprise, but also packaging structural engineers and graphic designers from design companies, as well as engineers from production enterprises such as printing plants
