PRODUCT PACKAGING ARRANGEMENT USING INVISIBLE MARKING FOR PRODUCT ORIENTATION

A system and method of arranging products, such as batteries, in a display package according to a desired orientation with efficient space utilization. The method includes providing products to be packaged, and applying an invisible orientation marking on each of the products. The orientation marking is visible when illuminated with ultraviolet light and is generally invisible to consumers under normal ambient light conditions. The method also includes illuminating the products with ultraviolet light, scanning each of the products, detecting the orientation marking on each of the products, orienting each of the products based on the detecting steps, and disposing each of the oriented products in a package so that the products have a desired orientation.
