Abstract:
The present invention relates to: a packaging material for a wire coil, the packaging material comprising a nonwoven fabric and a low-density polyethylene film; and a method for manufacturing same. The packaging material for the wire rod coil comprises: an outer polymer layer including ethylene vinyl acetate and low-density polyethylene; a non-woven fabric layer located below 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. A polypropylene non-woven fabric having a basis weight of 20 g/m2 to 50 g/m2 is used for the non-woven fabric layer to protect the packaged product from impact, and the non-woven fabric layer is self-adhesive. The packaging material is useful due to using linear embossing, thus having the effect of preventing breakage in a certain direction.
