The present invention relates to an earth bag for a vegetation retaining wall structure. The earth bag is formed of a felt, wherein the felt is manufactured by mixing eco-friendly materials, such as poly propylene, polyester, and PET bottle fiber in the proportion of 2:7:1, and includes a straw rope pad (20) stitched up with a side surface of the earth bag (10) by a needle punch and having a seed, a nutritional supplement, moss, and fiber. The earth bag for a vegetation retaining wall structure is cheaper than the conventional vegetation earth bag and is eco-friendly, strong, and long-lasting (more than 100 years) without separate ultra violet coating or functional treatment by supplementing the weaknesses of polyester that bearing and coupling capacities are weak and the weakness of poly propylene which is weak in ultra violet by mixing the PET bottle fiber in the felt. |
