The film, obtained from multiple suppliers, is 70-ga polypropylene, extrusion-laminated to 70-ga metallized polypropylene. Flexo-printing/converting procedures are performed by Genpak (www.genpak.com). The bag rollstock then is formed, filled, and lap-sealed on multiple f/f/s systems at three Humpty Dumpty production locations.
The snack processor had used PMS line work printing for these 50-g to 300-g bags. But this printing process had limitations. As Lynda Murray, vp of marketing for Humpty Dumpty, says, “I’m a big believer in the Opaltone® process. It gives us bolder, brighter graphic design capabilities and an endless range of color combination possibilities that make our packaging a more powerful marketing tool. Package appearance has been improved, and the printing is of consistent high quality. Consumers have responded positively to the new bags.”
