Abstract: An improved method of and machine for making a bulk container. The container has a main body which is strengthened as compared to at least the container top or bottom by at least one additional material layers, those material layers comprising in combination a single face liner and attached fluting medium. The variable layer construction being accomplished by machine combination of material layers of different cross-machine dimension. The method of this variable dimension multi-layer combination encompasses a single lamination step of the several material layers to provide a strengthened bulk container blank and therefrom the improved container of this invention.
