Hose packaging: create a Xintiandi in toothpaste

we use toothpaste every day, but we don't know that Xiaoxiao toothpaste has a development history synchronized with the reform and opening up. A drop of water can reflect the brilliance of the sun, but the progress and development of toothpaste confirm the footprints of reform and opening up. The author, Zheng Jianwei, is a senior engineer of Shanghai toothpaste factory. He specializes in the technology industry. He talks about toothpaste like a family treasure. Whether it's design ideas, production technology, management methods, development forecasts, future trends, it's very persuasive. We believe that the improvement of product quality, function expansion, design concept... All have infinite development space and no end. Innovation is a powerful driving force for the toothpaste industry. We are looking forward to Chinese brand toothpaste not only becoming a necessity of human life, but also a world-famous brand

toothpaste is an essential daily necessities for people. The functions of toothpastes have been continuously enhanced and the types have been increasing, and the packaging of toothpastes has also changed greatly. In particular, hose packaging, although seemingly inconspicuous, has attracted the attention of many packaging and printing manufacturers and achieved many enterprises. Taking Shanghai toothpaste factory of Shanghai white cat Co., Ltd. as an example, this paper takes you to explore the development path of toothpaste hose

at that time, restricted by the printing method, the toothpaste tube only used relief printing to print some words and color blocks, but failed to print images. Even if the text is printed, its quality is not high. The large print is rough, and Xiaoyu can't print it. For example, the "Zhonghua" toothpaste and "MAXAM" toothpaste produced by Shanghai toothpaste factory only have brand names on the surface of their toothpaste tubes. The background color of "Zhonghua" toothpaste is yellow and the characters are red; The background color of "MAXAM" toothpaste is white and the words are red. Due to the limitation of technical level, aluminum tube has become the only choice of toothpaste tube

composite hose initially appeared

aluminum tube dominated the world for a long time. About the early 1980s, the technology of producing toothpaste tubes with aluminum-plastic composite hose materials appeared in the foreign market. As the eldest brother of the domestic toothpaste industry, Shanghai toothpaste factory first saw this opportunity and began to study composite soft tube pipelines. However, in the mid-1980s, it was found that the composite hose pipe making equipment could not be implemented in China. There are two reasons for this: 1 There is a shortage of raw materials. Composite sheet is a blank in the Chinese market, and the shortage of raw materials leads to the failure of the pipe production line. ２. Backward technology. At that time, China emphasized self-reliance, so Shanghai toothpaste factory failed to go abroad and made things behind closed doors, resulting in the backward level of composite hose manufacturing and printing technology, and the stranded composite hose production line

composite hose reappearance

by the late 1980s, the national reform and opening-up policy was fully implemented, and the domestic toothpaste output had reached nearly 1billion tubes, which not only met the demand of the domestic market, but also partially exported. During this period, the development of functional toothpaste also accelerated. Under the condition that people attach equal importance to tooth cleaning and prevention and treatment of dental diseases, various medicated toothpastes came into being. At that time, there were about 300million tubes of medicated toothpaste, accounting for 30% of the total output, and it became the development trend of toothpaste in the future

the emergence of medicated toothpaste immediately exposed the disadvantages of aluminum tubes. Because some components contained in the medicinal toothpaste will react with the aluminum tube, there will be quality problems such as spots in the medicinal toothpaste packaged in the aluminum tube

in order to vigorously develop medicated toothpastes, the above problems must be solved. And set the temperature required for the experiment. Therefore, Shanghai toothpaste factory sprayed a thin layer of special substances like plastic on the inner wall of the manufactured aluminum tube to separate the toothpaste from the aluminum layer, but the uniformity of spraying was difficult to solve. There is no good solution in the world, so although the use of spraying technology reduces the quality failure, it does not fundamentally solve the problem

in the early 1990s, the time was ripe to adopt composite hoses, so Shanghai toothpaste factory chose composite hoses as the packaging of toothpaste, and introduced composite hose arm making equipment from Aisa company in Switzerland, becoming the first person to eat crabs in China. The choice of Shanghai toothpaste factory was not a whim, but mainly based on the following three considerations

first, in the late 1980s, Taiwan Sanying company has established a composite sheet production plant in the mainland, which has a certain scale, filling the gap of domestic composite sheets. Although the quality of composite sheet was not very good at that time, it could already meet certain needs. In addition, some manufacturers in the mainland have begun to produce composite sheets, and the previous problem of shortage of composite sheets has been solved

second, due to the introduction of relatively advanced foreign equipment, combined with the composite sheet of Sanying company, the previous technical problems have also been solved

III. The composite sheet can be printed by intaglio printing, and the printing quality has been greatly improved. Not only the printing color of large characters is relatively thick, and the smoothness is very high, but also fine words, such as product descriptions, can be printed

when the problems of raw materials, pipe making technology and printing technology are solved, the high cost has become a major factor restricting the development of composite hoses. At that time, the composite sheet needed 25 yuan per square meter, 60 toothpaste tubes could be made per square meter, and a toothpaste tube needed almost 0.4 yuan, resulting in an increase in the overall cost of toothpaste. The domestic market cannot accept this price, so the toothpaste packaged in composite hose is mainly exported. For example, the export volume of "MAXAM" toothpaste packaged with composite hose accounts for 3% to 4% of the total sales volume of "MAXAM" toothpaste in China. This situation continued until 1993. During this period, although the price of composite sheets decreased, it was still more expensive compared with aluminum tubes

the composite hose occupied the market with the addition of the deformation of the test piece

at the end of 1993, with the total thickness of the composite sheet and the thickness of the aluminum foil layer decreasing, the sheet price of the aluminum plastic composite hose decreased significantly; The composite sheet has been printed by flexographic printing, and the printing quality has been further improved; More and more domestic manufacturers supply composite hose sheets; International multinational companies Colgate and Unilever are also preparing to adopt composite hoses. This move shocked the toothpaste industry across the country. Under this background, Shanghai toothpaste factory took the opportunity to launch brands such as "spearmint", "white jade" and "acid proof" and began to enter the composite hose Market on a large scale. Other toothpaste manufacturers in China have also begun to adopt composite hose packaging. The market share of composite hose toothpaste has increased continuously, reaching 60%-70%. Aluminum tube toothpaste has no longer been valued by people

future development of toothpaste hose

future development trend of toothpaste hose, the industry believes that toothpaste will develop in the following two directions

I. thin aluminum plastic composite hose, that is, the total thickness of composite sheet is reduced to 200um, and the thickness of aluminum foil layer is reduced to 10um, or even thinner

II. All plastic composite hose. The use of

evoh material makes it possible to use all plastic composite hose. However, the barrier property has a great relationship with the thickness of EVOH material, so it cannot be produced in large quantities at present, but it is still the main development trend in the future

Shanghai toothpaste factory will continue to explore its own path of toothpaste hose, and adhere to exploring the way for the innovation of the national toothpaste industry to gain experience

reasons for choosing flexible printing

Shanghai toothpaste factory spent a long time to learn, understand and investigate the market, and found that flexible printing has great advantages in terms of cost, printing quality, production cycle and environmental protection. In particular, in recent years, it has become a printing technology with the fastest growth rate in the packaging and printing industry. Therefore, combined with the production characteristics of its own enterprise, it chose Heidelberg jieras flexible printing machine

the main reasons for choosing flexographic printing are:

1 Short version live parts production. The five major brands of Shanghai toothpaste factory are sold to more than 50 countries and regions. The market conditions are different, and the requirements for products are also different. Although the business volume is sufficient, and there are large, medium and small orders, it is mainly in medium and small batches. Compared with other printing methods, flexographic printing has the characteristics of low cost, short cycle, strong line processing ability and so on. It is suitable for printing short version live parts with moderate varieties and specifications, and has obvious advantages in production efficiency

２. The printing quality is good. The toothpaste hose design of Shanghai toothpaste factory is mostly based on the field and lines. Flexographic printing is superior to offset printing in both field and line printing, and is comparable to gravure printing. Facts have proved that the products printed by Shanghai toothpaste factory with flexographic printing are not only bright and eye-catching, but also thick on the ground. They have been recognized by customers and are deeply loved by users at home and abroad

３. The cost must be low. First of all, according to the characteristics of their own products, the selection and allocation of flexographic printing equipment based on the principle of economy and rationality can reduce investment, improve the utilization rate of equipment and improve market competitiveness. Secondly, the investment in environmental protection facilities of flexographic printing is much less than that of gravure printing. In addition, from the perspective of plate making and production, flexographic printing also has certain advantages. In short batch production, the plate making cost of flexographic printing is much less than that of gravure printing. Flexographic printing can achieve thin and uniform ink layer through the reasonable selection of embossing rollers. It can reduce the amount of ink, improve the drying performance, and save raw materials and energy

４. Conducive to environmental protection requirements. The UV ink used in the flexible printing aluminum-plastic composite hose has no volatile organic compounds, and there is no residual solvent in the printed matter, which is non-toxic, does not pollute the environment, and meets the requirements of environmental protection

flexographic printing has brought good economic and social benefits to Shanghai toothpaste factory
