High-Clarity, Cast Polypropylene Produce Pouch and Method

Abstract

A high-clarity, cast polypropylene produce pouch with first and second sidewalls and a bottom panel joined to form a pouch wherein the first and second sidewalls and the bottom panel are formed from cast polypropylene. The bottom panel can be a bottom gusset panel. The first and second sidewalls and the bottom gusset panel can have edges joined by side welding or heat sealing. Zipper or slide closures can close the first and second sidewalls. A method for forming a high-clarity, cast polypropylene produce pouch comprises creating a polypropylene (PP) resin, passing the polypropylene (PP) resin through a cast extruding machine and extruding molten polypropylene (PP) to produced extruded polypropylene (PP), rolling the extruded polypropylene (PP) in a cooling roller, and applying a surface-modifying corona treatment to the extruded polypropylene (PP).
