To preserve your cabbage be sure to store in in the refrigerator, and if you want it to keep long, you could store it in a plastic bag. Cabbage will last for several weeks. 

FreshFix Tip: Before using, remove any wilted outer leaves and wash thoroughly.  Slice the cabbage in half and remove the large white core.  Once the core is removed, slice into strips for shredded cabbage or prepare as directed.
