TIGHTLY PACKED is a term used to describe something that is filled with items in a way that leaves no space between them. This can be seen in the crossword solutions WEDGED (6 letters), DENSE (5 letters), and CHOCKABLOCK (11 letters). WEDGED implies that the items are pressed together in a way that creates a wedge shape, while DENSE suggests that the items are closely packed together.
