A hang hole in flexible packaging means a flat sealed header pouch with a die cut shape that allows a package to be placed on a retail display hook. The hang hole is usually near the top of the bag and is uses the added stabilit around the hole from the initial flat header seal. Holes are typically ¼" , but are also available in configurations such as OSHA (also known as Delta), and Sombrero (also known as Inverted T), to accommodate any retail display system.
