Abstract
Abstract A stack of flexible packaging bags, such as used in the meat packing industry in conjunction with automatic and semiautomatic packaging apparatus, made by assembling a multiplicity of flattened stacked wicket-holed bags on a flexible tubing binding threaded through the bag wicket holes to define a severable loop handle element, shank elements passing through the wicket holes in the stacked bags, and shank portion extensions adapted to secure the shank portions of the binding to wicket mounting means and to mount bag stack securing means.
