The subject invention generally provides a multilayer structure that includes a polymer mixture made from at least two polymer component materials. The invention particularly pertains to a multilayer structure containing an improved sealant layer and a polypropylene layer, wherein the sealant layer is made from a homogeneously branched ethylene polymer having particular molecular weight characteristics and a second ethylene polymer. The sealant layer has balanced properties such low heat seal and hot tack initiation temperature, a high hot tack strength and a broad hot tack seal window. The multilayer structure is particularly useful as a biaxially oriented polypropylene (BOPP) packaging film structure. |
