An expressive constraint programming (CP) formulation has been proposed to address the scheduling problem of a make-and-pack process. The resulting CP model is able to consider the typical processing stages of food industries in an integrated fashion, while capturing many features found in the industrial practice. The proposed CP formulation has been extensively tested and compared with other existing approaches. The results have shown that the model can efficiently solve medium and large-scale problem instances with multiple constraining features. The examples that have been solved show that the proposed formulation is computationally efficient
