Since the 1970s, great changes have taken place in the packaging of daily chemical products. Traditional metal and glass containers have been gradually replaced by lightweight plastic packaging. Moreover, the body of plastic bottles has become thinner and lighter. With the continuous emergence of energy, environmental protection, garbage disposal and other issues, since the 1990s, lightweight materials, exquisite printing, personalized design and advocating the concept of environmental protection have become the new trend of modern packaging. As a supplement, the appearance of flexible packaging is the biggest impact on the traditional daily chemical packaging. However, compared with traditional daily chemical packaging containers, flexible packaging has several problems that are difficult to solve: (1) it can only be used once and cannot be sealed repeatedly; (2) it can not provide various functional seals; (3) the relative appearance and style are single. These problems limit the development of flexible packaging, so that it has been only used as a supplement to bottled or small volume of disposable product packaging.
Can we combine the advantages of bottles with the lightweight and environmental protection of soft packaging? The appearance of an innovative way of sealing has changed people's way of thinking.
Market development of daily chemical flexible packaging
If a sealing cap is welded on the flexible packaging of daily chemical products, the packaging can have the advantages of both bottle and bag. This kind of packaging mainly has three forms: (1) welding at the oblique angle is the most popular way in the European market at present. It has the characteristics of convenient dumping, easy filling and good-looking shelf placement. It is generally used for supplementary packaging of more than 300 ml. (2) Welding at the top, is popular in Japan, generally used for small packaging products less than 100 ml. (3) Welded on the plane, very common in the United States, mainly used for large capacity (1 to dozens of gallons) of industrial packaging, there are generally cartons outside.
According to the function, the stamping soft packaging used in daily chemical products can be divided into supplementary packaging and final packaging. Supplementary packaging refers to the packaging with bottle packaging as the use packaging, and the soft packaging with cover as the second or multiple supplementary contents. Final packaging refers to: there is no other use of packaging, covered by the flexible packaging is the consumer's final use of packaging. It is worth noting that as a supplement to the inland market of China, the third kind is mainly used for industrial products, and it will take some time for China's industrial enterprises to update their technology and concepts, so there will be no obvious market development in the short term. However, due to the efforts of several large companies to promote the first two kinds of packaging methods, they have already performed well in the market. I believe that with the development of the domestic packaging system The improvement of bag welding technology will have great market potential.
