Analysis of potential problems of beer glass bottle packaging

compared with traditional glass bottle packaging beer, polyester bottle packaging beer has the advantages of safety (non explosion), light weight, low transportation cost, fashion and so on, which has been unanimously agreed by people inside and outside the industry and is indisputable. However, it cannot be denied that it has many shortcomings, such as soft material, easy to cause lax sealing, and short warranty period after all; In addition, it can't be disinfected at high temperature, can only pack draft beer, can't recycle and reuse bottles, and the cost is high. There are still problems in the key to the technical and economic feasibility. In China's beer market, the promotion of polyester bottle packaged beer has been ineffective, and it has not become a climate. Although relevant insiders shouted in the professional media: polyester bottles and bags imitate the application conditions to load beer has entered the "picking" season. Many people hold a wait-and-see attitude

the plastic packaging is a completely new update to the traditional beer packaging, just like the "big change" of product packaging in the beverage industry in those days. Look at today's beverage market commodity shelves: gas containing, non gas containing, large packaging, small packaging, catering consumption, family consumption, mobile consumption, all kinds of fashionable and even alternative packaging of beverage commodities, colorful, dazzling, endless. The "pop fruit steam" launched by Jianlibao last summer is simply packed in a more fashionable, novel and to some extent "alternative" package in the beverage market, which is really "hot". The following table lists the ultra-high molecular polyurethane handle currently used in spinal surgery. However, can the promotion of polyester bottles for beer and liquid food expand the market? But so far, the polyester bottle packaging of beer has always made little progress. The reason is:

● one of the problems: about the shelf life

the new national beer standard gb4927-2001, which was officially implemented on January 1, 2003, stipulates that the shelf life of bottled and tinned (raw and cooked) beer is not less than 60 days, and that of barreled (raw and cooked) beer is not less than 30 days; The shelf life of fresh beer shall not be less than 5 days

the production enterprise can mark the shelf life of the product on the label according to the beer type, the enterprise's own technical conditions and marketing conditions in accordance with the provisions of 4.5.1-4.5.2 respectively

the provisions and spirit of the above standards have great changes compared with the old standards: first, the shelf life time has been greatly shortened. The old standard stipulates that the shelf life is not less than 120 days, and some enterprises even mark it as 180 days; Second, this is a mandatory clause in the old standard. It seems that if it is not so, it can not guarantee the quality of beer and protect the interests of consumers. This is not the case

this is based on the fact that beer is different from other kinds of wine, such as Baijiu, yellow rice wine or wine. The older it is, the more mellow it is. The longer it is stored, the higher its value is. Beer sells "fresh goods". The shorter the period from production to consumption, the more guaranteed the freshness of beer and the higher its value. Its consumption quality is in line with time, which is just the opposite of other kinds of wine, such as Baijiu. If time is quality, for beer, the longer the time period from production to consumption, the greater the loss of freshness and quality. Therefore, in recent years, beer production enterprises have generally attached importance to freshness management. Some have promised to "consume the same day and the same week in the same city", others have promised to "consume the same month in the same province", and those who exceed the freshness management date will be unconditionally recalled. This mode of operation brings great brand benefits to beer enterprises, because it follows the maximization of consumer value. In the past, the shelf life of 4 months or even as long as half a year was essentially a continuation of the traditional quality requirements of canned food. It was in exchange for reducing the market risk of beer production and operation by damaging the freshness value of consumers to beer

"can't you sell beer? It doesn't matter. Anyway, the shelf life is long and there is plenty of time. Sell it slowly."

in view of this. Under the domination of the concept of the supreme freshness of beer and the maximization of beer consumer value, the structure and cost price of polyester bottle of beer should be appropriately graded according to the different shelf life of polyester bottle of beer, so as to achieve a more reasonable and competitive cost performance ratio of polyester bottle of beer. For beer, a specific commodity as a fast-moving consumer goods, it is crucial to make a breakthrough in this understanding

● problem 2: about traditional technology

packaging material suppliers focus on the research and development of PET beer bottles that have been pasteurized. Their starting point is the traditional process that the vast majority of Chinese beer, accounting for at least 90% of the total, is to obtain cooked beer with sufficient shelf life and shelf life after being pasteurized after filling. Even in order to adapt to the process conditions of high-temperature treatment after filling, the capping structure also inherits the traditional tinplate crown cap. This strategic positioning of trying to achieve "equivalent replacement" between polyester bottle packaged beer and glass bottle packaged beer out of compliance with the traditional process is expected to have the least resistance in market promotion

what is the actual situation

first of all, it is impossible for polyester bottle packaged beer to be completely "equivalent replacement" with glass bottle packaged beer

polyester bottles can follow the traditional process and meet the high-temperature process conditions of pasteurization, but this is bound to choose high-temperature polyester materials, which will lose a certain competitive advantage in cost and cost performance. Secondly, if we can start from the R & D purpose of maintaining and pursuing the maximization of consumer value, I'm afraid we should first put this project under the general trend and background of human consumption in the 21st century, the pursuit of nature and the return to nature, PP accounting for 17%[3], correctly guide consumption and offer consumers a new process of aseptic cold filling, which is different from the traditional process of cooked beer. Such a process route brings consumers more pure taste, Fresh beer with more nutrition. At the same time, due to the elimination of the traditional pasteurization and high-temperature treatment after packaging, polyester materials with more price competitiveness and higher cost performance can be selected. The traditional tinplate crown cap can also be replaced with a bright and beautiful plastic twist off cap that is easy to open and can be sealed repeatedly, which makes the whole product image of the new polyester bottle packaged beer look new, so that it is more attractive to consumers. Why not

besides, there are three basic conditions for aseptic cold filling of fresh beer: the first is the sterility of its own wine body, the second is the sterility of packaging materials, bottles and caps, and the third is the sterility of equipment, including the environment. Using polyester bottles can ensure the sterility of packaging materials in the aseptic cold filling of fresh beer in one step. Compared with using recycled glass bottles, the microbial risk is reduced by at least ten times, that is, an order of magnitude

weigh the advantages "Ma Ruiwen said the disadvantages. It is worth considering the choice of traditional technology and the decision-making of the initial goal of polyester bottles. (to be continued)
