摘要： The present disclosure relates to a recyclable polyethylene-based laminated packaging material with openability and a method of manufacturing the same including a multi-layered polyethylene film C in which a surface layer A and a sealant layer B are bonded to each other. The sealant layer B is a layer in which a polyolefin plastomer layer b1, a mixed resin layer b2 obtained by mixing a high-density polyethylene resin and a low-density polyethylene resin, and a composition layer b3 containing a resin composition obtained by mixing medium-density polyethylene and low-density polyethylene are sequentially laminated. Also disclosed is a method of manufacturing the same.
