Nonwoven bag is a kind of common shopping bag in China which implements plastic limit order, promotes environmental protection and reduces the use of plastic bags. But the promotion of the use of non-woven bags, will undoubtedly increase the operating costs of businesses, most businesses will be printed on the "environmental protection bags" on advertising, advertising costs to offset the use of cost. Now we simply introduce several mainstream non-woven fabric printing methods.

1, water printing with water-based elastic mortar as printing medium gets its name, it is more common in textile printing, also printing. When printing, color paste and water elastic glue reconcile. Wash the plate without chemical solvents, can be connected with water cleaning. It is characterized by good tinting power, strong covering and fastness, washable and almost no odor.

Generally manual printing, the advantages are: the price is cheaper; its disadvantages are: the color is not good control, printed out of the pattern is uneven.

3, heat transfer printing in the printing and special printing! This method requires intermediate media, that is, the printing and printing of the image to the heat transfer film or heat transfer paper, and then through the transfer equipment heating, the pattern transferred to non-woven fabric. The medium used in textile printing is heat transfer film. The advantages are: printing, rich patterns, comparable to photos.  It is suitable for small area color image printing.  Disadvantages are high prices and high printing costs.

4, gravure printing, this method is usually called non-woven fabric bags. This process is divided into two steps, that is, the traditional gravure printing is used to print the image on the film, and then laminating the patterned film on the non-woven fabric by laminating process. This kind of printing method is applied to non-woven bags with large area color pattern. It is characterized by exquisite printing, full use of machine printing, short printing cycle. In addition, the product has excellent waterproof properties, and the durability of the finished product is better than that of other printed non-woven fabric bags. The disadvantage is that there is a conflict with environmental protection, because of its complex film is difficult to degrade.
