상기 칼라탄성층(40)은 두께가 8mm내지15mm이고, 칼라칩에 중량비 15내지 30%의 폴리우레탄 바인더를 혼합하여 칼라칩이 서로 결합되게 하였으며, 표면이 매끄럽게 하기 위해 칼라칩의 입도는 2mm내지6mm인 것을 사용하였다. The color elastic layer 40 has a thickness of 8mm to 15mm, and the color chips are bonded to each other by mixing a polyurethane chip with a weight ratio of 15 to 30% to the color chips, and the particle size of the color chips is 2mm to smooth the surface. 6 mm was used.

상기와 같이 3개의 층으로 이루어진 포장재는 탄성을 높이기 위해 상기 탄성층(30)과 칼라탄성층(40) 사이에는 보조탄성층(35)을 더 형성할 수 있다. As described above, the packaging material having three layers may further form an auxiliary elastic layer 35 between the elastic layer 30 and the color elastic layer 40 to increase elasticity.

상기 보조탄성층은 두께가 25mm내지 35mm이고, 입도가 2mm내지10mm인 고무칩에 중량비 15내지 30%의 폴리우레탄 바인더를 혼합하여 고무칩이 서로 결합되게 함에 의해 구성되고, 고무칩 사이에는 미세한 투수용 공극이 형성된다. The auxiliary elastic layer is composed of a rubber chip having a thickness of 25mm to 35mm, and a rubber chip having a particle size of 2mm to 10mm by mixing a polyurethane binder with a weight ratio of 15 to 30% so that the rubber chips are bonded to each other.
