Non-woven bags generally use screen printing technology, which is often referred to as "silk printing", which has been a common printing process for many manufacturers. Generally, it is artificially printed. Because the printing has odor, the color is not full and easy to fall off, so many new non-woven printing methods have emerged. Here we introduce several mainstream models on the market:
1.the watermark
It is named for its use of water-based elastic glue as a printing medium. It is more common in textile printing, also called printing. The color paste and the water-based elastic rubber are blended during printing. The printing plate can be washed directly with water without using a chemical solvent. It is characterized by good tinting strength, strong hiding power and fastness, water wash resistance, and basically no odor.
2. gravure printing
The finished product processed in this way is usually called a laminated non-woven bag. The process is divided into two steps, that is, the conventional gravure printing process is used to print the graphic onto the film, and then the patterned film is laminated on the non-woven fabric by a laminating process. This process is generally used for non-woven bags of large-area color pattern printing. It is characterized by beautiful printing, full machine production, 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 both bright and matt finishes, matte with a matte finish! The product is stylish, durable, full of color, and the pattern is realistic. The disadvantage is that the price is relatively expensive.
3. thermal transfer
Thermal transfer is a special printing in printing! The method requires an intermediate medium, that is, the graphic is first printed onto a thermal transfer film or a thermal transfer paper, and then the pattern is transferred to the nonwoven fabric by heating by a transfer device. A medium commonly used in textile printing is a thermal transfer film. The advantages are: beautifully printed, rich in layers, comparable to photos. Suitable for small area color image printing. The disadvantage is that the printed pattern is easy to fall off and the price is expensive.
