Three-dimensional non-woven environmental protection bag

Non-woven bags (also known as non-woven bags, English: Nonwoven bags) is a green product, tough and durable, beautiful appearance, good air permeability, can be used repeatedly, can be washed, can be silk-printed advertising, logo, long service life .

The product uses non-woven fabric as raw material. It is a new generation of environmental protection materials. It has the characteristics of moisture-proof, breathable, flexible, light weight, non-combustible, easy to synthesize, non-toxic and non-irritating, rich in color, low in price, and recyclable. The material can be naturally synthesized when placed outdoors for 90 days, and it can be used indoors for up to 5 years. When it is extinguished, it is non-toxic, tasteless, and has no leftover substances, so it does not pollute the environment.

The commonly used environmental protection bags are:

Spunlace Nonwoven

The spunlace process is to radiate a high-pressure fine water stream onto one or more layers of fiber webs, so that the fibers are entangled with each other, so that the fiber webs can be reinforced and have a certain strength.

Needle punched non-woven

Needle-punched non-woven fabrics are a kind of dry-laid non-woven fabrics. Needle-punched non-woven fabrics use the piercing effect of needles to reinforce the loose web into a cloth.

With side and bottom printing

Non-woven bags generally use the screen printing process, which is often referred to as "screen printing", which is also a common printing process that many manufacturers compare to. It is usually printed manually. Because the printing 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:

Watermark with side and bottom

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, it can be washed directly with water. Its characteristics are good tinting strength, strong covering and fastness, washing resistance, and no peculiar smell at all. Commonly used for printing: canvas bags, cotton bags.

Gravure printing with side and bottom

The waste 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. Normal large-area non-woven bags printed with color patterns use this process. Its characteristics are exquisite printing, machine consumption throughout the process, and short consumption cycle. In addition, the product has excellent waterproof performance, and the durability of waste products is better than non-woven bags produced by other processes. The film is available in bright and matt, matte with a matte effect! The product is stylish and generous, durable, full-color, and realistic. The defect is that the price is relatively expensive.

Heat transfer with side and bottom

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 through the heating of the transfer equipment. The commonly used medium in textile printing is thermal transfer film. Its advantages are: exquisite printing, rich layering, comparable to photos. Suitable for small area color image printing. The disadvantage is that the printed patterns tend to be scattered over time and are expensive.

Product ordering method: can be customized according to customer requirements. For example: size 30*40*10, printed on the machine for copper plate color printing or walking table screen printing in 3 colors (spot color) Quantity: color printing and hot pressing more than 5000, monochrome silk screen sewing More than 2000 pieces, the material thickness can be ordered as required.
