Views: 88    

Non-woven bag is a green product. It has the characteristics of toughness and durability, beautiful appearance, good air permeability, reusable, washable, silk-screen advertising, marking, and long service life.

Non-woven bags use non-woven fabrics as raw materials and are a new generation of environmentally friendly materials. Non-woven fabrics are moisture-proof, easy to decompose, rich in color, low in price, and recyclable. The material can be naturally decomposed when placed outdoors for 90 days, and the service life is as long as 5 years when placed indoors. When burning, it is non-toxic, tasteless, and has no leftover substances, so it does not pollute the environment. Non-woven bags generally use silk-screen printing, which has always been a common printing process for many manufacturers. It is usually printed manually, but because the printing process has peculiar smell, the color is not full and easy to fall off, so many new non-woven printing methods have emerged. Here we introduce the mainstream ones on the market.

1. Watermarking process

The watermark process gets its name because of its use of water-based elastic glue as the printing medium, and it is more common in textile 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, and washing resistance. This printing process basically has no peculiar smell.

2. Gravure printing

Products processed in this way 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 its durability is better than that of non-woven bags produced by other processes. The film is available in bright and matte, and the matte has a matte effect! The product is stylish and durable, with realistic patterns, but the disadvantage is that it is a little bit expensive.

3. Thermal transfer printing

Thermal transfer printing belongs to special printing in printing! This method requires an intermediate medium, that is, the graphics and text are printed on the thermal transfer film or the thermal transfer paper, and then the pattern is transferred to the non-woven fabric by heating by the transfer device. The commonly used medium in textile printing is thermal transfer film. Its advantages are that it is beautifully printed, has a rich sense of layering, and is comparable to photos. It is 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.
