It basically depends on process, the product and quality requirements of the final product. In my view i think there is no standard packaging machinery, the best machinery to use for any process is basically what will produce desired product,quality requirements and satisfies your production requirements(i.e output, less downtime, operation duration e.t.c.)
So if cheap chinese machinery meets your production requirements and regulatory requirements then its the best machinery for operations. There is no need to buy something very expensive one..
