Bags made from double-sided bonded needle-punched non-woven fabric, which is produced using raw materials such as polypropylene (PP) or polyester fiber (PET). These bags undergo rigorous selection for their thickness, unit weight, physical and mechanical properties, appearance, fiber type, load-bearing method, direction, geometric dimensions, and water permeability, as well as equivalent pore size to meet the requirements for plant growth. They feature UV resistance, aging resistance, non-toxicity, non-flammability, and the characteristic of not extending when torn, truly achieving zero pollution. Mainly used for constructing flexible ecological slopes. The protection and greening of ecological slope bags is one of the important construction methods for desertification control, mine reclamation, highway slope greening, riverbank slope protection, and riverway improvement.
The XinGeng ecological bags boast excellent physical and chemical properties. This specially formulated material can withstand UV degradation, is unaffected by chemical substances in the soil, and does not undergo quality change or rot. They are highly durable, resistant to pests, anti-aging, non-toxic, and can resist erosion from acids, bases, salts, and microbial decomposition. These bags allow water permeation but not soil, being plant-friendly and suitable for vegetation greening.
Moisture-resistant
Eco-bags are moisture-resistant; they do not absorb water, and water presence will not damage the bag or cause deformation. They are also non-soluble in contaminated liquids (EPA Method 9090).
Chemical Resistance (pH)
Extensive research and testing show that eco-bags have strong resistance to certain concentrations of acidic and alkaline chemicals, making them suitable for the majority of solid waste and severely polluted sites.
Anti-biodegradable and animal-resistant
Eco-bags are made from a special formula material that does not support, absorb, or aid in the growth of fungi. They do not rot, mold, or deteriorate. Eco-bags are not digestible by insects or related animals and will not serve as food for rodents, termites, woodworms, beetles, silverfish moths, and the like.
Anti-UV high polymer
Ecological bags can withstand high temperatures up to 150 degrees Celsius without melting and can endure low temperatures down to -40 degrees Celsius.
Ultraviolet (UV) Protection
Eco-bags contain carbon ink and other UV-resistant ingredients.
Here's an example to illustrate using the equivalent aperture:
One: Hole diameter too large (bag body, material too thin)
2. The aperture is too small (the bag body material is too thick)
It hinders the growth of vegetation and the extension of root systems, severely affecting the structural stability of flexible slopes.
C. The increased hydrostatic pressure along the slope due to this will cause the slope to collapse.
Advantages and Features
In slope engineering, this new material can completely replace stone, cement, and other materials, significantly reducing construction costs. The post-construction slope features a surface suitable for vegetation coverage, achieving a greenification effect on the excavated slope, creating a natural ecological slope. It has a filtering function that allows water to pass through but retains soil, resulting in a highly permeable slope. This slope offers strong protection and stabilization against soil erosion, localized mud (and) rock flows, and slope collapses, making it a durable and stable natural slope.

Specs and Parameters Editing
Design Specifications
Flat Size Range: (Customizable according to design and engineering requirements)
Fabric weight range: Varies widely, commonly including 100g, 125g, 150g, etc.
Fabric tensile strength: ≥4.5 kN/m
Fabric elongation at break: ≥40%
Formula for calculating the volume of soil after forming into eco-bags:
Length = bag length - (12~15) cm
Width = 0.7 x the width of the ecological bags
Height = 0.4 x Eco Bag Height
Example: Bags with an outer diameter of 810mm x 430mm will measure approximately 65cm in length, 30cm in width, and 15cm in height after filled with soil (The specifications of eco-bags and their shaped dimensions after filling can be designed according to actual requirements. Allowable deviation is up to 2%).
Benchmark Reference
Currently, there is no national or industry standard for ecological bags in our country. The technical parameters refer to the National Standard of the People's Republic of China for Geotextile Nonwoven Fabric by Spunbond, Needle Punched, and Staple Fiber, GB/T 17639-2008.
