A packaging system is configured to package a product to form a packaged product assembly. The packaging system includes a lid including a major panel, side panels, and a tab extending from one of the side panels. The packaging system also includes a box hingedly coupled to the lid that includes side walls and a bottom wall with a slot defined therein. The product may be retained by the lid against the major panel by first and second end flaps. As the lid and box are folded toward one another, the product may be loaded into the box and the tab and an adhesive member coupled thereto may extend through the slot in the bottom wall of the box. The adhesive member may then be adhered to a back surface of the box to retain the product in the packaging system. Related methods are also provided.
