Introduction to the printing process of non-woven bags
Non-woven bags generally use the screen printing process, which is often referred to as 'screen printingGenerally, it is printed manually. Because the printing has peculiar smell, the color is not full and easy to fall off, so many new non-woven printing methods have emerged. Here we introduce several mainstream ones in the market:
Watermark printing
Named because of the use of water-based elastic glue as the printing medium, it is more common in textile printing, also called printing. Mix the color paste and the water-based elastic glue when printing. No chemical solvent is needed when printing the plate, and it can be washed directly with water. It is characterized by good tinting strength, strong covering and fastness, washing resistance, and basically no odor. Generally used for printing: canvas bags, cotton bags.
Gravure printing
The finished product processed by this method is usually called a laminated non-woven bag. This process is divided into two steps, that is, the traditional gravure printing process is used to print the graphic on the film, and then the film with the pattern is laminated on the non-woven fabric by the lamination process. This process is generally used for non-woven bags printed with large-area color patterns. It is characterized by exquisite printing, machine production in the whole process, and short production cycle. In addition, the product has excellent waterproof performance, and the durability of the finished product is better than that of non-woven bags produced by other processes. The film is available in gloss and matt, and the matte has a frosted effect! The product is fashionable, durable, full of color, and realistic in pattern. The disadvantage is that the price is relatively expensive.
