|China's packaging industry has been used for more than 20 years, and has completed the development path of developed countries in the past 40 years. Basically, it changed the situation of "first-class products, second level packaging and three flow prices". The packaging industry has developed from a scattered and backward industry to a complete and complete industrial system with a certain modern technical equipment and a relatively complete classification. The remarkable characteristics of the packaging industry today are the internationalization of the packaging market, the globalization of the packaging industry and the interdependence and interdependence of the development of packaging industry in all countries.
In the Western Zhou Dynasty, the engraved technology combined with the ancient smelting technology, the appearance and development of the cast or engraved bronze ware. The end of Qin, stone wind becomes more and more popular, which makes this ancient carving technology leap development from two aspects of quality and quantity, and seal the precedent. It has made an important contribution to the development of Chinese cultural undertakings. At the same time, it also creates opportunities and conditions for the further development and improvement of manual carving technology. A lute and India since the Qin and Han brick mold, widely used and extended the hand carved paper copy operation belongs to the field of application. As for the rubbing and operation and further development of the textile printing, the essence is in the shape of printing.
|Custom Printed Packaging
Now a day, the Custom Printed Packaging is very popular all over the world,it's use colorful print technology on the suraface of the packing materials, In the same pages with different color version printing, color picture effect will reach text, picture, etc. the plate, ink, pressure and other processes, so that the ink transferred to the surface of paper, textiles, leather and other materials, bulk copy the content of technology. Now color printing generally uses flat printing.
Color printing is a direct or indirect way to make images or text originals as a printing plate, coated with ink on the printing ink, the ink is transferred to the paper or other substrates by pressure, and a large number of rapid replication of an industrial engineering.
Now color printing generally uses flat printing.
Lithographic printing is sometimes called chemical printing, which means that the printed image is in the same plane as the printing plate. It is based on "water immiscible" principle of printing. This type of printing is done by mechanical or manual means on the stone or metal surface, and then the surface of the chemical treatment, so that the image part of the ink, while the other blank part is not ink. When printing, only the ink image part is transferred to the paper to form the imprinting. Photographic printing, photocopying and printing are lithographic printing.

|Aluminum is a silvery white light metal. Ductility. The products are usually columnar, rod, flake, foil, powder, ribbon and filiform. A layer of oxide film to prevent metal corrosion can be formed in humid air. The acid treated aluminum powder heated in the air can burn violently and emit a dazzling white flame. Soluble in dilute sulfuric acid, dilute nitric acid, hydrochloric acid, sodium hydroxide and potassium hydroxide solution, insoluble in water, but can react with hot water slowly to produce aluminum hydroxide, the relative density of 2.70, elastic modulus 70Gpa, Poisson's ratio 0.33. Melting point 660. Boiling point 2327. It is widely used for its light, good conductivity and thermal conductivity, high reflectivity and oxidation resistance. Do the daily dish aluminum is usually called "steel" or "steel". The thermal expansion coefficient of Al at (25) Shi Wen is 0.0000236mm/ C or 23.6ppm*k-1.|
