Pickles have a long shelf life and do not get spoiled for months, why?

Table salt, sugar vegetable oils and sodium benzoate, etc. are used as preservatives. These do not allow moisture and air to enter the material and hence, bacteria cannot thrive on them. Therefore, pickles do not get spoiled for months.
