I believe what you are talking about are "fresh pack" pickles:
Fresh pack or quick process pickles are not fermented. Instead, the acid necessary to preserve this product is added in the form of a ‘pickling solution’ of vinegar and spices. Sugar may also be added. Popular pickles such as bread-and-butter, and fresh pack dill are examples of this type of pickle. Also in this category are fruit pickles and relishes.
Hope this helps.
