One of the most commonly used and admired packaging boxes in rectangular boxes is straight tuck end boxes. These boxes are simple in design and easily adjustable as well. The straight tuck end boxes have a front and back for the designing and printing of the box and two openings. Both ends have flaps on each opening and get folded inward then the larger flap that is attached to the front of the box folds around the sides and tucks into the back of the box to complete its shape.
