Ecological bags are a high-strength, UV-resistant, freeze-thaw-resistant, and acid-base-resistant eco-synthetic material, representing a new type of special material. They possess high strength UV resistance, acid-base resistance, corrosion resistance, and can remain non-degradable for over 70 years, truly achieving zero pollution. Primarily used for constructing flexible ecological slopes, these bags are moisture-resistant, do not absorb water, and are not damaged by moisture; they do not deform and are not soluble in polluted liquids, making them an excellent tool for ecological protection and highly practical. The bags are made from double-sided heat-set needle-punched nonwoven fabric, which is produced from raw materials such as polypropylene (PP) or polyester fiber (PET). Strict selection is made for the thickness, unit weight, physical and mechanical properties, shape, fiber type, stress mode, direction, geometric dimensions, and water permeability of the UV-resistant ecological bags, as well as the equivalent aperture to meet plant growth requirements. They feature UV resistance, aging resistance, non-toxicity, non-flammability, and the characteristic of not extending cracks, truly achieving zero pollution. They are mainly used for constructing flexible ecological slopes, slope protection greening, and are one of the important construction methods for mountain restoration, mine reclamation, highway slope greening, riverbank protection, and river treatment.

The Eco Bags feature excellent physical and chemical properties. This specially formulated material is resistant to UV degradation, unaffected by chemicals in the soil, and does not undergo quality change or rot. It is non-degradable, pest-resistant, aging-resistant, non-toxic, and resistant to acid, alkali, salt erosion and microbial decomposition. They allow water to pass through but not soil, are plant-friendly, and suitable for vegetation greening.
