Non-woven bags are now more and more widely used, and non-woven bags are needed in many occasions.So we have to consider the load-bearing performance of non-woven bags. The general non-woven bag can support weight of about 10kg. If we want to bear more weight, we should improve the following process, which will greatly increase the load-bearing performance of the non-woven bag.1.Use sewing non - woven bags as much as possibleThe sewing non-woven bag has better load-bearing performance than the ultrasonic  non-woven bag.because the ultrasonic non-woven bag is only thermally bonded together by high temperature, all the forces are subjected to a thermal melting point, so the heat-fusible non-woven bag is not strong in bearing capacity.2. Make cross at the handle of the non woven bagThe force of  the non-woven bag during the movement will be carried out at the four points of the handle non-woven bag.  If the load-bearing performance of these four points is difficult to tear, the load-bearing performance will be greatly enhanced. Therefore, we do the cross treatment in the handle area, which is very useful to improve the load-bearing performance of the non-woven bag.3. The handle sew to bottom or full circle4. Because the force of  the non-woven bag during the movement will be carried out at the four points of the handle non-woven bag.If we make the handle sew to bottom or full circle,It’s load-bearing performance will be greatly enhanced,will not only depend on the 4 points of the handle.All the two side will bear the weight.We made a test,one 40*40*20cm non woven bag with the handle sew to bottom or full circle.In the normal speed movement of pedestrians, the non-woven bag is not affected by the pulling force to tear or break.

When it comes to environmental protection bags, we have to mention non-woven bags.Because it has largely replaced plastic bags, it has become an environmentally-friendly bag that is now recognized.Non-woven products are colorful,fashionable,eco-friendly,widely-used and elegant,pattern and styles are various,it’s light ,environmental and recycled.They are recognized as environmentally friendly products that protect the earth's ecology.1. Water-repellent,breathable:The polypropylene slice does not absorb water, the water content is zero, the finished product has good water repellency, and is composed of 100% fiber with porosity, good gas permeability, easy to keep the cloth surface dry and easy to wash.2. Non-toxic, non-irritating products are produced in accordance with FDA food grade raw materials, contain no other chemical components, stable performance, non-toxic, no odor, no irritating to the skin.3. Antibacterial, anti-chemical agents: Polypropylene is a chemical blunt substance, no insects, and can isolate the presence of bacteria and insects in the liquid; antibacterial, alkaline corrosion, the finished product does not affect the intensity due to erosion.4. Light weight: Polypropylene resin is the main raw material for production. The specific gravity is only 0.9, only three-fifths of cotton, which is fluffy and feels good.5. Soft: Made of fine fibers (2-3D), light-point hot melt bonding. The finished product is soft and comfortable.6. Good physical properties. It is made by directly spinning polypropylene into a mesh, and the strength of the product is better than that of the general staple fiber product, the strength is non-directional, and the longitudinal and transverse strengths are similar.7. In terms of environmental protection, the raw material of most non-woven fabrics used is polypropylene, and the raw material of plastic bags is polyethylene. Although the two substances have similar names, they are far from chemically different. The chemical molecular structure of polyethylene has considerable stability and is extremely difficult to degrade. Therefore, it takes 300 years for the plastic bag to be decomposed. The chemical structure of polypropylene is not strong, and the molecular chain can be easily broken, so that it can be effectively degraded. And in the non-toxic form into the next environmental cycle, a non-woven shopping bag can be completely decomposed within 90 days. Moreover, the non-woven shopping bag can be reused more than 10 times, and the environmental pollution degree after disposal is only 10% of the plastic bag.

Non-woven bags are generally printed by screen printing, which is often referred to as "silk printing".Many manufacturers always use this type,It is usually printed by hand and can only be printed in monochrome or two-color. Moreover, the printing has an odor, and the color is not full and easy to fall off. Therefore, many new non-woven printing methods have emerged.There are some other ways of printing: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. It is used to reconcile color paste with water-based rubber. The printing plate can be washed directly with water without using a chemical solvent. It is characterized by good tinting strength, strong opacity and fastness, washable, and no odor. The price is more expensive than screen printing.Generally used for printing: canvas, cotton, oxford, and some smooth surface fabric etc.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.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 layering, 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.
