The development trend of the most popular color pr

With the continuous improvement of people's living standards, the pursuit of the outer packaging of goods will become stronger and stronger, the requirements for the folding times and aging resistance of the covers of books, periodicals and notebooks will become stronger and stronger, and the consideration of cost performance and environmental factors will become more and more. For the future packaging and printing industry, There will be some important development trends as follows:

considering the many advantages of paper plastic mulching, this decoration method will not be eliminated in the past decade or even decades. On the one hand, the recycling technology of paper and packaging used in paper plastic mulching has made great progress, It is necessary to offset and control the balance position of the excitation center of the exciter, so as to change the load-carrying force property of the output of the electro-hydraulic exciter. Some special beating and filtering equipment and more advanced recycling processes have emerged to remove waste and recycled materials containing paper and plastic film

on the other hand, it is also necessary to develop recyclable water redispersible or soluble plastic film and adhesive for film covering as soon as possible. When the paper plastic film covering products made of this kind of adhesive and film can be recycled, they can be dispersed or dissolved in the pulp under the conditions of water, appropriate acid or alkali, appropriate temperature and pressure stirring, and become a part of the pulp, which can enhance the paper produced from recycled raw materials. From the research and development situation in this regard, the scale of the water-based paper plastic film coating new material industry may reach 2trillion yuan this year. The glue is relatively easy to be redissolved or dispersed when recycled, while the plastic film is much more difficult to be redissolved and dissolved after the paper plastic film is coated. The main problem is how to reduce the product cost and make it equivalent to BOPP plastic film

the ideal environment-friendly glazing oil is non polluting to the environment during and after production, and the product does not contain any volatile organic compounds or its content can be ignored; The finished product not only has good gloss, but also has a flexible film, which is not easy to be stained, broken or scratched. It has the same folding resistance, water resistance and reinforcement as the coated product of carton; The product is easy to recycle after use, that is, under the conditions of water or appropriate acid, alkali or other chemicals, heating, stirring, etc., these varnish cured products are easy to dissolve and disperse in the pulp and become a part of the pulp. From the current application research situation, there is no technical obstacle for water-based glazing oil to achieve these, but the cost of coated products is much higher than that of paper plastic coating

BOPP, polypropylene biaxial tensile film, is almost used in the current paper plastic film. This kind of film has the advantages of low price, good gloss and high light transmittance according to the relevant laws and regulations. However, the biggest disadvantage is the lack of aging resistance, especially the poor photodegradation resistance. Therefore, There are obvious deficiencies in packaging the covers of high-end library books or diaries, high-end gift boxes and other rare printed items with this film. Before long, these BOPP plastic films will degrade, pulverize and lose luster, while the bet film, polyethylene terephthalate resin film, does not have this problem, but the price is more than 30% expensive, but it is nothing for high-end books and packaging that may be permanently preserved, It's just that many people don't realize this problem
