Analysis on the development of toothpaste hose packaging in the future

toothpaste is an essential daily product for people. Under the condition of the continuous enhancement of the function and increase of the types of toothpaste, the packaging of toothpaste has also undergone great changes, especially the 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. Here, I would like to thank Mr. zhengjianwei, senior engineer of Shanghai toothpaste factory, for his support

According to Mr. Zheng, the predecessor of Shanghai toothpaste factory was the China chemical industry society established in 1912, which mainly produced some daily chemical products, such as Sanxing toothpaste, Sanxing soap, etc. After liberation, it was renamed Shanghai toothpaste factory, specializing in the production of toothpaste. The toothpaste packaged in flexible tubes originally made of lead and tin was not packaged in aluminum tubes until the 1960s

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 characters are printed, the quality is not high. The large characters are printed coarsely, and Xiaoyu still can't print them. For example, Zhonghua toothpaste and MAXAM toothpaste produced by Shanghai toothpaste factory. On the surface of its toothpaste tube, there is only the brand name. The background color of Zhonghua toothpaste is yellow and the characters are red; The background color of MAXAM toothpaste is white and the characters 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. He began to study composite soft tube pipelines, but in the mid-1980s, he found that composite hose pipe making equipment could not be implemented in China. For this, Mr. Zheng summarized two reasons

(1) 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 did not go abroad, and there was a feeling of making cars behind closed doors, resulting in the backward technical level of composite hose pipe making and printing, which stranded the composite hose production line

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 needs of the domestic market, but also partially exported. During this period, the development of functional toothpaste also accelerated the maintenance of tensile testing machine. 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. 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 not easy to solve. There is no good solution in the world, so the use of spraying technology has reduced the above quality failures, but it has not fundamentally solved the problem

91. Before the Jinan gold assay experiment, according to the requirements of striking energy, the time was ripe to adopt composite hoses in the early 1990s, 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. According to Mr. Zheng, the choice of Shanghai toothpaste factory was not groundless, mainly based on the following three considerations

(1) 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

China Academy of space technology has reached cooperation with Guangya Aluminum Co., Ltd. and Guangdong Zhenglai Technology Co., Ltd.

(2) due to the introduction of relatively advanced foreign equipment, coupled with the composite sheet of Sanying company, the previous technical problems have also been solved

(3) 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 the fine text (product description) 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 at least 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 with composite soft arms is mainly exported. For example, the export volume of MAXAM toothpaste packaged with composite soft arms 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

composite hose launched a large-scale attack

at the end of 1993, with the total thickness of composite sheet and the thickness of aluminum foil continuously decreasing, the sheet price of 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 preparing to adopt composite hoses. This move shocked the toothpaste industry nationwide. Against this background, Shanghai toothpaste factory took the opportunity to launch spearmint, white jade, acid proof and other brands, 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 continues to increase, reaching 60% to 70% in China's plastic machinery market. Aluminum tube toothpaste is no longer valued by people

when talking about the future development trend of toothpaste tubes, Mr. Zheng talked about his views. He believed that toothpaste tubes would develop in the following two directions

(1) thin aluminum plastic composite hose, that is, the total thickness of composite sheet is reduced to 200 m, and the thickness of aluminum foil layer is reduced to 10 m, or even thinner

(2) all plastic composite hose. The use of EVOH material makes it possible to use all plastic composite hose, but the barrier property has a great relationship with the thickness of EVOH material, so it can't be produced in mass 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. We sincerely hope that they will always be at the forefront of the toothpaste industry in China

why choose flexographic printing

as a recruit to enter the printing industry, Shanghai toothpaste factory spent a long time to learn, understand and investigate the market, and found that flexographic printing has great advantages in cost, printing quality, production cycle and environmental protection, especially in recent years, it has become a printing process technology with the fastest growth rate in the packaging and printing industry, so combined with the production characteristics of its own enterprise, Heidelberg jieras flexographic printing machine was selected

Mr. Zheng explained in detail the reasons for choosing flexographic printing:

1. Suitable for the production of short version live parts

the five brands of Shanghai toothpaste factory are sold to more than 50 countries and regions. Different countries and regions have different market conditions and different requirements for products. Although the business volume is sufficient and the orders are large, medium and small, they are 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 on-the-spot and line based. In the field of flexographic printing, the effect of line printing is better than offset printing, and is equal 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, which has been recognized by customers and deeply loved by users at home and abroad

3. Low cost

first of all, according to the characteristics of their own products, choose and match flexographic printing equipment on the principle of economy and rationality, which 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. To reduce ink consumption, improve drying performance, and save raw materials and energy

4. Conducive to environmental protection

the UV ink used in the flexible printing aluminum-plastic composite hose has no volatile organic compounds, and the printed matter has no residual solvents, 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
