Engineering Plastics are reactive modified plastics such as polyolefins and contain chemical functions such as maleic anhydride, Maleic acid, acrylic acid, sodium acrylate or epoxide (glycidyl methacrylate) and ..., and polymer alloy which produced via reactive blending process' modified plastics are widely used in extrusion coating and offer excellent adhesion on many supports, and are compatible with a large number of polymers and difficult substrates such as printed films. They are used in a large number of applications, such as coextrusion binders or tie layers in multilayer structures for the packaging industry, pipeline coatings, cables and hotmelt adhesives'
