Abstract
A substantially flat flexible wrap for incoherent, flowable products is described, containing inside at least a rigid roundish body which prevents a complete flattening and crushing of the wrap when compressed between substantially flat bodies. An emission or loss of the flowable products in the wrap is thus avoided.
