Common process of non-woven bag making machine

Non-woven bags generally use the screen printing process, which is often referred to as “screen printing”, which has always been a common printing process for many manufacturers. Because it is generally manual printing, and the color of the process is not easy to control, as customers continue to improve the degree of exquisite printing of products and environmental protection requirements, many new non-woven printing methods have emerged. Here we first introduce the common process of non-woven bag making machine:


Heat transfer
Thermal transfer is a special type of printing in printing! 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 by heating the transfer device.

It is named after its use of water-based elastic glue as the printing medium. It is more common in textile printing and is also called printing. Blend the color paste and water-based elastic glue when printing. No chemical solvents are used when washing the printing 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 peculiar smell.

Gravure printing
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. Generally, non-woven bags printed with large-area color patterns use this process. Its characteristic is that the printing is exquisite, the whole process is produced by machine, and the production cycle is short. 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! The disadvantage is that it conflicts with the concept of environmental protection, because the film is difficult to degrade.
