A disposable carton is disclosed which is adapted to hold a stack of copy sheets equivalent to a plurality of reams for a printing machine. The carton is constructed of portions which are sequentially removed to expose the stack and permit the operator to carry the stack to a sheet supply platform without disrupting the stack. A remaining portion of the carton which serves to permit the operator to place the stack upon the platform is adapted to be slideably removed from under the stack thus effecting the loading of the stack in the printing machine preparatory to the sheet feed operation.
