Technical test of flexible packaging materials

As we all know, the development of soft packaging materials in China is only in the past 20 years. Especially in the past ten years, through the large-scale introduction of raw material film production equipment, printing equipment and composite equipment, the production, development and use of soft packaging materials are increasing, new products and new materials emerge in endlessly, the physical evaluation of materials is more and more important, and the testing technology and various performance test methods are marked The test of plastic soft packaging materials is of great significance to control the quality of plastic products, guide processing, study the physical properties and structure relations of plastic materials, and understand the scope of use. The development of testing instruments can be said to be with the development of economy and continuous development.
The technical test of soft packaging materials is as follows:
1. Familiar stage of test instrument
In 1980s, soft packaging testing instruments began to enter China. Some national quality inspection institutions and universities purchased or imported directly through associations. Some enterprises introduced production equipment and bundled instruments, and the frequency of use was very low. Domestic instruments are almost vacant. The product quality awareness is also very thin, the importance of material testing is not familiar with, and the development is slow.
2. Slow growth of test instruments
2.1 from the beginning of 1990s to the end of 1990s, with the development of soft packaging industry, the research of domestic testing instruments gradually appeared, but it is still slow. The paper packaging test is the main test in packaging. By the late 1990s, the research on soft packaging testing was increasing gradually, such as Jinan Languang, a professional research and development of soft packaging testing instruments, has been developing and growing, which greatly promotes the progress of the industry; There are also many companies that are specialized in importing test instruments. They have undoubtedly played a certain role in the soft packaging market. However, the high price and many factors of imported products limit the development of soft packaging product inspection.
