Design Considerations For MDO-PE Polyester Replacement Structures, 24FlexPack Conference

Polyester (PET) print webs find extensive use in flexible packaging. Machine Direction Oriented Polyethylene (MDO-PE) films are an increasingly prevalent recyclable alternative to PET, as companies start to focus more on sustainability. PET functions well as a print web because of its high heat resistance, low haze, and high stiffness. However, these three variables often conflict with each other when designing and producing an MDO-PE print web. Moreover, bubble stability and a low gel count are essential for process stability and must be considered. This presentation will examine the relationship between stiffness, haze, extensibility, heat resistance, bubble stability, and low gel count in an MDO-PE print web.
