A new heuristic algorithm for the heterogeneous MCLP(Multiple Container Loading Problem) is proposed in this paper. In order to solve MCLP, this algorithm generates an initial solution by applying the new SCLP(Single Container Loading Problem) algorithm to given boxes with sequential loading strategy. An improvement algorithm improves the initial solution by reducing the total number of containers of the solution. The SCLP algorithm generates single container by filling empty spaces with the homogeneous load-blocks of identically oriented boxes and splits residual space into three sub spaces starting with an empty container. A loading pattern of the container is built by applying this approach recursively until all boxes are exhausted or no empty spaces are left in the container. Numerical experiments with 47 test cases show the good performance of this new algorithm
