Non-woven flour bags usually use screen printing technology, which is often referred to as "screen printing", which is a common printing process used by many manufacturers. Generally speaking, manual printing, because the printing has peculiar smell, the color is not full, and it is easy to fall off, so many new non-woven printing methods have appeared. Here we introduce several current mainstream markets:

1, watermark

Because it uses water-based elastic paste as a printing medium, it is more common in textile printing, also known as printing. Color paste and water elastomer are mixed during printing. The printing plate can be washed directly with water without chemical solvents. It is characterized by good tinting power, strong hiding power and fastness, good water resistance, and basically no peculiar smell. Generally used for printing: canvas bags, cotton watermark printing bags

2. Gravure printing

The products processed in this way are usually called laminated non-woven flour bags. The process consists of two steps: firstly, the traditional gravure printing process is used to print pictures and texts on the film, and then the patterned film is bonded to the non-woven fabric by the laminating process. This process is usually used for large-area color pattern printing of non-woven flour bags. 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 non-woven flour bags produced by other processes. The film has two choices, bright and matte, and matte polishing effect! The product is stylish and generous, durable, full of colors, and realistic design. The disadvantage is that the price is relatively expensive.

3, thermal transfer

Thermal transfer is a kind of special printing in printing. This method requires an intermediate medium, that is, printing graphics and text on a thermal transfer film or paper, and then transfer the pattern to the non-woven fabric through a heating transfer device. The commonly used medium in textile printing is thermal transfer film. Its advantages are: exquisite printing, rich layers and comparable photos. Suitable for small area color image printing. The disadvantage is that the printed pattern is easy to fall off for a long time, and the price is expensive.
