06 Aug 2018 --- Researches at Virginia Tech have created innovative “slippery” plastic packaging designed to minimize the food waste commonly left behind in condiment, dairy and beverage packaging. The study, which was published in Scientific Reports and has yielded a provisional patent, establishes a method for wicking chemically compatible vegetable oils into the surfaces of common extruded plastics. While cutting down on food waste, the “slippery” packaging also helps combat the frustration felt by consumers when they are unable to squeeze the last drop of sauce from small packets.
