The main material of non-woven eco-friendly bags is non-woven fabric. Non-woven fabric is a kind of non-woven fabric, which directly uses polymer chips, short fibers or filaments to form new fiber products with soft, air-permeable and flat structure through various web forming methods and consolidation technologies.
Several varieties currently mainstream on the market:
One, watermark
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 the printing plate is washed, 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. Generally used in canvas bags and cotton bags.
2. Gravure printing
The finished products processed by this method are usually called laminated non-woven bags. 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. 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 bags produced by other processes. The film is available in bright and matt, and matte has a matte effect! The product is stylish and generous, durable, full-color, and realistic. The disadvantage is that the price is slightly more expensive than the usual silk-printed non-woven fabric.
Three, 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 to the non-woven fabric by heating the transfer device. 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.
