The Butterfly Pack unit-dose packaging was developed for single-handed dispensing using a sachet format. It is made from two high-barrier films, a flexible top web and a semi-rigid forming web. To dispense, the pack is picked up by using one hand. By squeezing the opposite edges toward each other, the pack folds and snaps open, providing an engineered and controlled release of the contents. Features and benefits of the pack include accurate product dosing to eliminate product overfill, controlled dispensing to avoid accidental spills, lower costs versus bottles and tubes, and improved image quality versus wrinkled and hard-to-open sachets.
