THERMOPLASTIC FILM STRUCTURES WITH A LOW MELTING POINT OUTER LAYER
摘要
<p>A film structure including at least a base layer containing a thermoplastic polymer and at least an outer layer containing a low melting point polymer. Methods of manufacturing the film structure, including the steps of coextruding melts corresponding to the individual layers of the film structure through a die and thereafter: simultaneously biaxially stretching the coextruded film sheet; or sequentially biaxially stretching the coextruded film sheet, wherein the machine-direction orientation (MDO) is performed with a radiant-heated MDO stretcher. An extrusion-coated film structure exhibiting strong bond adhesion, and a method of manufacturing the same are also provided.</p>
