Six characteristics of gravure printing for aluminum foil bag and plastic packaging bag
1. The amount of ink used in Lou printing is determined by the depth of the concave part of the picture and text part of the printing plate. When printing, the depth of the concave part of the picture and text part is relatively fixed, so the ink amount is also relatively stable;
2. The inking method of gravure printing is that the plate cylinder is directly immersed in the ink trough to receive the ink, or the ink is coated on the plate cylinder by the ink transfer roller, which saves many ink transfer rollers and adjustment devices of ink quantity;
3. Gravure printing ink transfer than offset printing and flexographic printing, so the product text ink layer thick, strong three-dimensional sense;
4. Gravure printing is mostly rotary printing with high speed and strong ability;
5. Gravure printing has a wide range of substrate materials, and it has good adaptability for plastic packaging bags and composite materials which are easy to extend and deform;
6. Gravure printing uses easy drying ink and non absorbent plastic packaging film.
Bag knowledge: main characteristics of aluminum foil bags
1. It has light weight, metallic luster, good light repellency and high reflection ability to heat and light. Metal luster and reflection ability can improve the brightness of printing color;
2. Good isolation, strong protection, impermeable to gas and water vapor, prevent moisture absorption and gasification of the contents, and are not easy to be damaged by bacteria and insects;
3. The aluminum foil bag has good shape stability and is not affected by temperature change;
4. It can't bear force, has no sealing property, has pinhole and easy to wrinkle, so it is not used alone in general. It is usually processed with paper and plastic film to make composite material, which overcomes the disadvantages of non sealing property, and its advantages such as isolation are fully developed. http://m.switzerland-hotel.com/
