Problems solved by technology

At present, the ordinary film that has been used in my country as a packaging material technology and equipment has many disadvantages. The product is easily contaminated, and it is easy to bring harmful substances such as bacteria into it when it comes into contact with people and food, which is not conducive to people's health. In the direction of clean processing, easy recycling of products, ultra-thin adhesive layer, diversified decoration methods, and aseptic and multi-functional products, the special antiseptic film for book-folding will finally replace the traditional film-for-folding technology with its many advantages.
[0003] With the development of the economy and people's attention to their own health, the quality of printed matter is facing higher and higher requirements. In recent years, the process of copy film has also changed from the original high-quality, short-cycle development to the use of advanced Craftsmanship and non-toxic raw materials produce products that utilize people's health and protect the ecology, but have not yet developed to the effect of sterilization. At the same time, the basis of the management system has also been extended from the ISO9000 quality management international standard to the ISO14000 system environmental management international standard, and to printing enterprises. The new concept of "clean and environmentally friendly" is proposed, which all indicate that the development of Fushu film technology has entered a new era of environmental protection
