       How to continuously improve the level of packaging post press processing technology and enhance the added value of products is a problem that the packaging industry needs to face and solve in the future.Packaging Post Printing Process To Improve The Added Value Of Packaging

        Among all the packaging forms, paper packaging is the most widely used. This is because paper packaging has many advantages: low material cost, convenient processing and printing; Low transportation and storage cost, recyclable, conducive to environmental protection and so on.Packaging Post Printing Process To Improve The Added Value Of Packaging

      Therefore, among the four pillar packaging materials of paper, plastic, metal and glass, paper packaging has the fastest growth. Packaging Post Printing Process To Improve The Added Value Of Packaging

       Among all post press processing processes, polishing, die-cutting, bronzing and film coating are the most widely used and fastest developing. Packaging Post Printing Process To Improve The Added Value Of Packaging

      So, what is the current situation and development prospect of paper packaging post press processing in China? Packaging Post Printing Process To Improve The Added Value Of Packaging

      This paper takes paper packaging post press processing and these four post press processing technologies as the analysis object to carry out a deeper discussion.Packaging Post Printing Process To Improve The Added Value Of Packaging

Development status of paper packaging post press processing technology   Packaging Post Printing Process To Improve The Added Value Of Packaging   

         There is still a certain gap between China’s post press processing technology and foreign countries. For example, there are more medium and low-grade products and less high-grade products in packaging products;Packaging Post Printing Process To Improve The Added Value Of Packaging  

         In addition, the basic raw materials, mechanical equipment and technology are relatively backward, and the overall management level of the industry is not high, resulting in the relatively slow development of the whole paper post printing processing industry.Packaging Post Printing Process To Improve The Added Value Of Packaging   Packaging Post Printing Process To Improve The Added Value Of Packaging

Environmental protection glazing, price is the key   Packaging Post Printing Process To Improve The Added Value Of Packaging

      Glazing is to change the physical characteristics of paper surface luster through the flow cloth and calendering of glazing coating on the surface of printed matter.Packaging Post Printing Process To Improve The Added Value Of Packaging

       When glazing, the coating thin layer coated on the paper has high transparency and smoothness; Packaging Post Printing Process To Improve The Added Value Of Packaging

      The glossed paper packaging printed matter not only increases its surface smoothness, but also can protect the printed pictures and texts on the packaging.

       Beautify, protect and prolong the service life of the paper packaging printed matter;Packaging Post Printing Process To Improve The Added Value Of Packaging

        It also creates good conditions for subsequent processing processes (such as die-cutting or paste box), so glazing technology is widely used in paper packaging post printing processing.Packaging Post Printing Process To Improve The Added Value Of Packaging

        The polishing process is simple, cheap, easy to operate, and can be used for full plate polishing or local polishing according to the actual needs. Packaging Post Printing Process To Improve The Added Value Of Packaging

      Therefore, it is very popular in printing enterprises. The initial polish is solvent based, which has poor polishing effect and is not conducive to environmental protection.Packaging Post Printing Process To Improve The Added Value Of Packaging

            However, the research and development of water-based glazing and UV glazing solve this problem. From the current market situation, the trend that aqueous glazing and UV glazing will eventually replace solvent glazing is irreversible. Packaging Post Printing Process To Improve The Added Value Of Packaging

       Nevertheless, there is still a certain gap in the environmental protection atmosphere actively advocated by China and Western countries. 

       Taking the United States as an example, the United States Environmental Protection Agency (EPA) has put forward restrictions on the content of organic volatiles in ink and coating products, which will become more and more strict over time. Packaging Post Printing Process To Improve The Added Value Of Packaging

       At present, the market share of solvent glazing in the United States has decreased from 80% to less than 15%.Packaging Post Printing Process To Improve The Added Value Of Packaging

       At present, some domestic enterprises have adopted water-based glazing and UV glazing. However, due to the high price of these two kinds of glazing oils, many units will only apply water-based glazing and UV glazing technology on the packaging of some high-grade products in consideration of cost.Packaging Post Printing Process To Improve The Added Value Of Packaging

        while solvent glazing will still be adopted on the packaging of most low-grade products.Packaging Post Printing Process To Improve The Added Value Of Packaging

Speed, the main breakthrough of die cutting    Packaging Post Printing Process To Improve The Added Value Of Packaging   Packaging Post Printing Process To Improve The Added Value Of Packaging

         Die cutting and indentation are carried out on various trademarks, cartons and other packaging prints according to the graphic shape and design requirements, so that the edges of packaging prints show various shapes. Packaging Post Printing Process To Improve The Added Value Of Packaging

      After die-cutting, the packaging printed matter can be produced into various shapes of outer packaging, which not only beautifies the product, but also improves the appreciation of the outer packaging and the added value of the product.  Packaging Post Printing Process To Improve The Added Value Of Packaging

       Post press processing is the weakest link in China’s printing industry. There is a big gap between domestic enterprises and foreign enterprises in terms of technology, equipment, materials and management.   Packaging Post Printing Process To Improve The Added Value Of Packaging

      Die cutting processing technology is undoubtedly the key to a breakthrough in the field of packaging post printing.Packaging Post Printing Process To Improve The Added Value Of Packaging

       In foreign countries, packaging and printing enterprises have widely used laser cutting system for die-cutting processing. Packaging Post Printing Process To Improve The Added Value Of Packaging

      The cutting system controls die cutting with automatic program, which has the advantages of high speed, high precision and good repeatability.Packaging Post Printing Process To Improve The Added Value Of Packaging

       Now many domestic enterprises are aware of this.Packaging Post Printing Process To Improve The Added Value Of Packaging

          Some powerful enterprises have begun to adopt laser cutting system. According to incomplete statistics, there are dozens of laser die-cutting plate making factories in China. Packaging Post Printing Process To Improve The Added Value Of Packaging

       At present, domestic die-cutting machine products are mainly concentrated in medium and low-grade levels, and most of the high-grade die-cutting machines used by domestic enterprises are still imported products.Packaging Post Printing Process To Improve The Added Value Of Packaging

       At present, the maximum accuracy of domestic equipment is ± 0.15mm, while that of foreign products has reached ± 0.1mm. Packaging Post Printing Process To Improve The Added Value Of Packaging

       The highest speed of die-cutting machines of international well-known manufacturers Bobst and Germany Wuba can reach 12000 pieces per hour, while the highest speed of domestic products is only 8000 pieces per hour. Packaging Post Printing Process To Improve The Added Value Of Packaging

         The backwardness of equipment strictly limits the development of domestic die-cutting technology. Therefore, the development of high-speed die-cutting machine is the main breakthrough in the innovation of domestic post press processing equipment.Packaging Post Printing Process To Improve The Added Value Of Packaging

Improving performance is the primary task of bronzing

        Bronzing is to use the template installed on the hot stamping machine to press the printed matter and hot stamping foil in a short time with the help of a certain pressure and temperature, and transfer the metal foil or pigment to the surface of the hot stamping printed matter according to the picture and text of the hot stamping template.Packaging Post Printing Process To Improve The Added Value Of Packaging

        Its purpose is to increase the luster and decorative effect of printed matter and improve the commodity value and grade of printed matter.Packaging Post Printing Process To Improve The Added Value Of Packaging

        It is widely used in the post press processing of high-grade products such as trademarks.Packaging Post Printing Process To Improve The Added Value Of Packaging

        high-grade packaging, hardcover book covers, greeting cards, calendars and so on.Packaging Post Printing Process To Improve The Added Value Of Packaging

         The quality of bronzing process mainly depends on the quality of bronzing equipment and bronzing template. The bronzing machine of stora company in Germany can reach 12000 sheets / hour, and the quality of bronzing template is very high. Packaging Post Printing Process To Improve The Added Value Of Packaging

       The bronzing packaging products produced are of high quality and high grade. Packaging Post Printing Process To Improve The Added Value Of Packaging

       At the same time, the price of the equipment is also very expensive. Compared with imported bronzing equipment, domestic bronzing equipment has obvious advantages in performance and price. Packaging Post Printing Process To Improve The Added Value Of Packaging

      The price of domestic machine is only equivalent to 1 / 5-1 / 4 of the price of similar foreign products.Packaging Post Printing Process To Improve The Added Value Of Packaging

        However, the overprint accuracy, stability and function of imported machine are obviously better than domestic machine.Packaging Post Printing Process To Improve The Added Value Of Packaging

        It is also more durable than domestic machine, and is more suitable for the processing of fixed batch high-grade packaging products.Packaging Post Printing Process To Improve The Added Value Of Packaging

Film coating process is still widely used

       The processing technology of coating adhesive on the surface of transparent plastic film treated by corona and hot pressing with printed matter to form paper-plastic composite printed matter is called lamination. Packaging Post Printing Process To Improve The Added Value Of Packaging

       Like the glazing process, it is to increase the surface gloss and protect and beautify the packaging. It is widely used in the surface finishing of book covers, high-grade packaging, etc.Packaging Post Printing Process To Improve The Added Value Of Packaging

        Because plastic film is mainly used in film covering, it brings great harm to environmental protection. Although the plastic film has high transparency, good gloss and low price,Packaging Post Printing Process To Improve The Added Value Of Packaging

        it can not be degraded, difficult to recycle, easy to cause white pollution, and long-term use will endanger the health of workers. Packaging Post Printing Process To Improve The Added Value Of Packaging

        In addition, solvent based adhesives also contain toxins, which are easy to cause harm to human body. Now in Europe and the United States, the film covering process has been included in the category of elimination process, Packaging Post Printing Process To Improve The Added Value Of Packaging

        And began to vigorously develop the glazing process. Packaging Post Printing Process To Improve The Added Value Of Packaging 

      Because the film coating process is applied earlier in China, and the outer packaging after film coating is beautiful and durable, it still has a large market share in China and is still widely used.Packaging Post Printing Process To Improve The Added Value Of Packaging

Advantages of paper packaging post press processing technology  Packaging Post Printing Process To Improve The Added Value Of Packaging

        When consumers buy products, they first touch the outer packaging of the products. Therefore, the outer packaging with exquisite appearance and excellent workmanship can easily attract people’s attention and increase their desire to buy. Packaging Post Printing Process To Improve The Added Value Of Packaging

       At the same time, the outer packaging is also required to protect the product. Packaging Post Printing Process To Improve The Added Value Of Packaging

        Therefore, in the post press processing of paper packaging, a large number of post press processing technologies such as polishing, die cutting, bronzing and film coating have become the favored means of many packaging enterprises. Packaging Post Printing Process To Improve The Added Value Of Packaging

        The use of many post press processes in paper packaging post press processing mainly has the following advantages:Packaging Post Printing Process To Improve The Added Value Of Packaging

Development direction of paper packaging post press processing technology  Packaging Post Printing Process To Improve The Added Value Of Packaging

       From the development level of the whole packaging industry, there are still obvious gaps and deficiencies in the paper packaging industry, mainly in the following aspects: Packaging Post Printing Process To Improve The Added Value Of Packaging

       first, the overall modern management level is not high and the economic benefits are not ideal; Second, the product grade needs to be improved. Packaging Post Printing Process To Improve The Added Value Of Packaging

       Medium and low-grade products can still meet the needs of various industries, but the product renewal speed is slow, and there is still a shortage of high-grade and high-performance packaging products; Packaging Post Printing Process To Improve The Added Value Of Packaging

        Third, basic raw materials and mechanical equipment are backward; Fourth, the speed of technological progress is slow.Packaging Post Printing Process To Improve The Added Value Of Packaging

      With the development of science and technology and the improvement of people’s awareness of environmental protection, the disadvantages of traditional paper packaging post printing processing processes such as polishing, bronzing, die cutting and film coating have been paid more and more attention. Packaging Post Printing Process To Improve The Added Value Of Packaging

      Although the traditional processing method has low cost, green packaging is more advocated than the serious problem of environmental protection.Packaging Post Printing Process To Improve The Added Value Of Packaging

       Green packaging has a 3r1d principle, That is, the product packaging is reduced, easy to reuse, easy to recycle and degradable (degradable). Packaging Post Printing Process To Improve The Added Value Of Packaging

      In addition, the outer packaging materials of products should be non-toxic and harmless to human body and organisms, and the whole process of packaging products from raw material collection, material processing, product manufacturing,.

        Product use, waste recycling to final treatment will not cause harm to human body and environment.Packaging Post Printing Process To Improve The Added Value Of Packaging

      These not only meet the requirements of environmental protection, but also adapt to the shortage of resources in today’s world.

      The trend of realizing sustainable development also meets the development requirements of an energy-saving society.Packaging Post Printing Process To Improve The Added Value Of Packaging
