Composite Packaging Film: "Color Revolution"

From April 13th to 15th, the Chinese Packaging Technology Association held the 2004 national plastic packaging film industry new products and deep processing technology seminar on the information conveyed that high barrier, multi-functional soft plastic packaging materials, has become the current domestic plastic The development of the packaging industry is hot. At the same time, breakthroughs in bag making and printing technologies enabled the composite packaging film to enter the 'Color Revolution' era. The development of multi-layer co-extrusion technology in China has also changed the product structure of functional films and containers, and has adapted to the high demands of environmental protection.
According to Liu Xiaomei, chief engineer of China Packaging Technology Association, after more than 20 years of development, China's plastic packaging materials have formed a certain scale. Private enterprises such as Jiangyin Shenda Group and Zhejiang Dadongnan Group started from several thousand yuan and have grown to more than 1 billion yuan. The leading enterprises of the small and medium-sized plastic packaging enterprises have gained vitality through structural adjustment, asset restructuring, and technological transformation. The gap with foreign technology levels has gradually narrowed.

At present, high-barrier, multi-functional soft plastic packaging materials have become a hot spot for domestic development in recent years, and a number of new products and technologies have emerged. Not only has the high barrier property, multifunctional cling film and aseptic packaging film developed rapidly, but the original composite film has also been developing in a deeper way. The color printing technology is increasingly widely used, and the whole industry already has offset, gravure and flexographic color systems. Promote the development of soft plastic packaging materials in depth; the successful development of anti-counterfeiting packaging films, especially anti-static packaging films, is also of great significance.

With the growing demand for environmental protection, it is particularly important to reduce the amount of garbage produced under the premise of satisfying packaging functionality, and to make packaging films and packaging containers more lightweight and thinner. The use of adhesives and solvents used in the production of high-barrier films based on dry processes tends to pollute the environment, and the development of co-extrusion packaging films has resulted in low investment, low cost, strong adaptability and easy operation. At present, China's co-extrusion technology has made new progress, with the exception of the superposition head technology of Dalian Liaonan Dongfang Machinery Co., Ltd., which has been promoted and applied. The five-layer co-extruded high-barrier film blowing machine developed by Guangdong Jinming Plastic Equipment Co., Ltd. and other domestic co-extruders Blow molding equipment also began production.

In addition, at the seminar attended by more than 100 companies, packaging film equipment companies in Germany, the United States, Japan, Italy, Austria and other countries also brought their latest achievements, and will undoubtedly promote the domestic level of plastic packaging film industry. The rapid increase.
