Non woven handbags generally use screen printing technology, which is often referred to as "silk screen printing", which has always been a common printing technology used by many non-woven bag manufacturers. Generally manual printing, so the color of the process is not easy to control, so many new non-woven printing methods have emerged.
1、 Watermark
It is named because it uses water-based elastic glue as the printing medium. It is common in textile printing, also known as printing. When printing, mix the color paste with water-based elastic glue. When developing printing plate, chemical solvent is not used, and water can be directly used for washing. It is characterized by good coloring power, strong covering and fastness, water washing resistance and basically no peculiar smell.
2、 Gravure printing
The finished product processed by this method is usually called peritoneal nonwoven bag. This process is divided into two steps, that is, the traditional gravure printing process is used to print the picture and text on the film, and then the film printed with the pattern is compounded on the non-woven fabric by the film covering process. This process is generally adopted 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. Films are available in bright and matte. Matte has frosting effect. The disadvantage is that it conflicts with the concept of environmental protection, because the film is difficult to degrade.
3、 Heat transfer printing
It belongs to special printing in printing! The method requires an intermediate medium, that is, the picture and text are printed on the heat transfer film or heat transfer paper, and then the pattern is transferred to the non-woven bag by heating the transfer equipment. The common medium in textile printing is heat transfer film. Its advantages are: exquisite printing, rich hierarchical edition, comparable to photos. Suitable for small area color image printing. The disadvantage is that the price is high and the printing cost is high.
