         As a recognized green technology, solvent free composite technology has been widely used in the field, especially the solvent free composite machine, which has become the leading technology and development direction in the field of composite soft packaging.
  Solvent free composite technology was invented in Europe in the mid 70s of last century. After more than 30 years of development, as a recognized green technology, solvent free composite technology has been widely used in the field, and has become the leading technology and development direction in the field of composite soft packaging.
  Widely used
  At present, the proportion of solvent free composite technology in Europe and the United States has reached more than 70%, and the proportion of the new solvent free composite machine is as high as 80%~90%.
At present, it is recognized that the solventless complex maker of the overall technology mainly comes from Germany, Italy, Spain, France and Japan. The general high mechanical speed is about 350 m / min, and the minority reaches 450 m / min, and the high has reached 600 m / min. At present, the speed of the imported solventless composite machine in China is between 200 m / min and ~350 M / s. Other countries and regions, such as India, Brazil, Turkey and so on, though also have factory production, but the level of technical performance is relatively low.
  Narrowing the gap
  In the mid and late 90s of last century, China began to introduce solvent-free laminating machine. Due to various reasons of subjective and objective, although the solvent free compound machine has been introduced for many years, the effect in the past has not been satisfactory for a long time. From the objective point of view, the main reasons are that there are several aspects, the solvent free compound is a new technology in our country, and the domestic talent system is difficult to meet the requirements; secondly, the product adaptability and technical support of the foreign suppliers are not completely in place; again, the high price of equipment and adhesives limits the scope of use.
  According to incomplete statistics, by the end of 2011, China has installed about 100 sets of such equipment. In spite of the rapid growth in the last two years, the total number of solventless composite machines is only 2% ~ 3%, which is not only far below the developed countries and regions, but also far below the average level.
  The progress of adhesive technology
  
has promoted the development of solvent-free composite products.
  It is necessary to use domestic equipment and adhesives to replace the imported products, to make the foreign products domestically made and to provide complete technological support. Happily, Guangzhou Tong Ze Machinery Co., Ltd., as a system supplier with solventless complex equipment and technology as the leading product in China, has developed a number of patent products after many years of unremitting efforts to provide different uses and specifications for various kinds of soft packaging enterprises and adhesives manufacturers. Preparation and related technical support.
  The development of homemade solvent-free composite adhesives has been developing rapidly, and the quality and output have been significantly improved. There are many manufacturers of solvent free composite adhesives at home, including Shanghai Kangda chemical new material Limited by Share Ltd, Beijing koau new material Limited by Share Ltd, Yantai Wanhua Beijing Research Institute and Huzhou and American Chemical Co., Ltd. Overall, the domestic adhesive has basically met the market demand, and in some respects, it has exceeded the trend of imported products.
  In recent years, with the continuous increase of people's awareness of environmental protection, health and safety, as well as the increasing pressure of cost and emission, people pay more and more attention to the solvent free complex, especially the continuous improvement of the domestic solvent free composite equipment and adhesives, and the popularization of the solvent free composite technology. The new quantity of solvent free composite machine has increased exponentially. The development of solvent free composite technology in China has seen an unprecedented good situation.
  According to the systematic analysis of the product structure, most of the existing composite packaging products in China (about 80% or more) can be completed by the solvent free complex process. Therefore, solvent-free composite will have broad prospects for development in China.
