Zusammenfassung: | The present invention relates to a wire coil packaging material including non-woven fabrics and low-density polyethylene films and a manufacturing method thereof. The wire coil packaging material includes: an outer polymer layer containing ethylene vinyl acetate and low-density polyethylene; a non-woven fabric layer located under the outer polymer layer; and an inner polymer layer located under the non-woven fabric layer and containing ethylene vinyl acetate and low-density polyethylene. By using a polypropylene non-woven fabric with a basis weight of 20 g/m^2 to 50 g/m^2 in the non-woven fabric layer, it is possible to protect a packaged product from shocks and have a self-adhesive characteristic. The present invention has an effect of not breaking in a certain direction by using a linear emboss, thereby being useful as a wire coil packaging material.
본 발명은 부직포와 저밀도 폴리에틸렌 필름을 포함하는 선재 코일용 포장재 및 그 제조방법에 관한 것으로서, 선재 코일용 포장재는 에틸렌초산비닐과 저밀도 폴리에틸렌을 포함하는 외부 폴리머층과, 외부 폴리머층 하부에 위치하는 부직포층과, 부직포층 하부에 위치하고, 에틸렌초산비닐과 저밀도 폴리에틸렌을 포함하는 내부 폴리머층을 포함한다. 부직포층에 평량이 20g/m2 내지 50g/m2인 폴리프로필렌 부직포를 사용하여 포장된 제품을 충격으로부터 보호하고, 자가점착성을 가진다. 선형 엠보를 사용하여 일정 방향의 파단이 발생하지 않는 효과가 있어서 선재 코일 포장재로 유용하다. |
