The Calwis Company, established in 1945, is a manufacturing and innovation concern located in Green Bay, Wisconsin. Our core areas of expertise include screen printing, chemical filling and dry powder filling. However, we have extensive experience in complementary areas, often using plastic as the medium, where our innovation is brought to bear. Calwis produces both finished goods as well as component parts. With a wide range of customers, our Company is capable of executing small-volume speciality items that require delicate precision work as well as high-volume runs of less complex designs.
