Several commonly used printing methods for non-woven bags

In the past, non-woven bags generally used traditional screen printing methods. This printing process has relatively simple technical requirements and relatively high printing efficiency, so many manufacturers have been using this printing process until now. However, this printing method is usually manual printing, because the printing has peculiar smell, the color is not full and easy to fall off, so the disadvantages are relatively large, so many manufacturers have begun to try new non-woven printing methods. The following is a summary of the market Several common printing methods. 1. Thermal transfer Thermal transfer is a special printing in printing! The commonly used medium in textile printing is thermal transfer film. Its advantages are: exquisite printing, rich layers, comparable to photos. Suitable for small area color image printing. The disadvantage is that the printed pattern is easy to fall off over a long period of time and is expensive. This method requires an intermediate medium, that is, first print the graphics on the thermal transfer film or thermal transfer paper, and then transfer the pattern to the non-woven fabric by heating the transfer device. 2. Watermark Watermark is one of the more common printing methods of non-woven bags. Watermark is also called printing.

Gravure printing Gravure printing belongs to the current non-woven bag printing which is relatively high-end and the printing is more realistic. It is also called peritoneal non-woven bag. 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 bright and matt, and matte has a matte effect! This process is divided into two steps, that is, the traditional gravure printing process is used to print the image and text on the film, and then the film with the pattern is laminated on the non-woven fabric by the laminating process. The product is stylish and generous, durable, full color, realistic patterns, the disadvantage is that the price is relatively expensive. Peritoneal non-woven bag.
