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

Abstract

The invention discloses a composite book type sterilizing film. The sterilizing film is of a three-layer structure, i.e. A layer, B layer and C layer, wherein the A layer is a sterilizing layer and comprises 92 to 94 percent of polypropylene, 3 to 5 percent of antibacterial master material and 3 percent of anti-adhesion agent; the B layer is a core layer and comprises 97 to 99 percent of polypropylene and 1 to 3 percent of anti-static smooth master material; the C layer is a composite contact layer and comprises 96 to 98 percent of polypropylene and 2 to 4 percent of anti-adhesion agent. A production process of the composite book type sterilizing film comprises the following steps of (1) feeding the materials; (2) performing melt extrusion; (3) casting sheets; (4) longitudinally stretching the sheets; (5) horizontally stretching the sheets; (6) performing drawing and edge cutting; (7) coiling; (8) cutting; and (9) obtaining the finished product. A 100 percent sterilizing effect can be achieved, bacteria can be directly killed after different people use the film, the transmission of diseases is avoided, and meanwhile the repeated utilization factor of the product is also increased. Therefore, the sterilizing film has great market prospects.

Description

technical field [0001] The invention relates to a book-folding type bactericidal film, which belongs to the technical field of polymer material processing and application. Background technique [0002] Nowadays, the awareness of environmental protection and hygiene in the packaging and printing industry is increasing, and it is imperative to develop and apply pollution-free and pollution-free "green" materials and processes. 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. Developing in the direction of clean processing, easy recycling of products, ultra-thin adhesive layer, diversified decoration methods, and sterile and multi-functional products, the special antiseptic film for book-folding will ...
