A bag or package which can separate and retain fines or particles filtered from the contents of the bag or package is disclosed. The bag or package may be dual-layered. The inner layer, or second layer, may include one or more grates, holes, mesh portions, openings, perforations, or slits disposed in one or more surfaces of the second layer. The openings can filter fines or particles from the contents of the second layer into a gap or pocket formed between a portion of the inner layer and the outer layer, or first layer. Alternatively, the bag or package may be single layered and include a septum in its interior. The septum can have one or more openings that filter fines or particles from the contents of the bag into a gap or pocket.
