1, non-woven bags screen printing process
This is a commonly used printing method, the price is moderate, so many manufacturers use some methods. This printing method through the LOGO document to make a film, and then can be through the film to sun screen, after the sun will be made into a printing version of the screen, before printing. When the sun is very critical, if the version of the sun is not good, the effect of printing out will be very poor, there will be the phenomenon of hairy edges. Screen printing and divided into two kinds of manual screen printing and machine screen printing, is a more traditional way of printing.

3, non-woven bags laminated printing process
Finished products processed with this method is usually called laminated nonwoven bags. First, the traditional gravure printing process will be printed to the film, and then the laminating process will be printed with the pattern of the film composite on the non-woven fabric. Generally higher requirements or more color pattern non-woven bags will use this process. It is characterized by exquisite printing, machine production and fast production speed. The finished product has excellent waterproof performance, and the durability of the finished product is also better than the non-woven bags produced by other processes. Laminated: there are two kinds of bright film and matte film, but its cost is relatively high.
4, non-woven bags thermal transfer printing process
In the printing belongs to the special printing! The printing method requires intermediate media to complete, that is, the first graphic printing to the thermal transfer film or thermal transfer paper, and then transfer the pattern to the non-woven fabric through the transfer equipment heating. The common medium used in textile printing is heat transfer film. This printing beautifully, with a rich layered version, comparable to photos, but the printing costs are higher.
5, non-woven bags heat sublimation printing
Is a role through the role of water will be printed on the surface of different material objects transfer technology, water transfer is divided into water label transfer and water phi transfer surface phi two, only through the water you want to print the pattern to a variety of objects which is the most widely used printing nowadays. As long as the special adhesive film on the surface of the water and then sprayed with a reactive agent can make a variety of shapes on the object with a new coat, and the effect and durability of the same as baking paint almost everything printed. But the cost of this process is relatively high.
6, non-woven bags watermarking process
Because of its use of water-based elastic pulp as a printing medium and named, more common in textile printing, also called printing. When printing the color paste and water-based elastomeric glue blend. When washing the printing plate without chemical solvents, can be directly rinsed with water.
