When crossing into a foreign country, local authorities are concerned about FRESH fruit and vegetables. Processed and packaged fruits and vegetables are rarely of concern. Most, if not all of the insects or parasites that "piggyback" on fresh items are usually eliminated by the processing.
So, yes, dried fruit is fine to take into any EU country. Packaging is immaterial.
Also, once you are there, dried fruits (& nuts) are called "fruta seco." They are sold everywhere, and are typically found adjacent to each other in any supermercado. When asking for either, use the "fruita seco" phrase.
I hope this helps.
