Abstract
A packaging method and apparatus wherein each product is packaged by capturing the product in flexible packaging material. The packing apparatus includes a product detector for detecting the presence or absence of a product to be packaged. The detection of the product may cause the advancement of packaging material and the product through a nipping station to form a package. The failure to detect a product may cause the advancement of the packaging material to stop and conserve packaging material until a product is detected. The product detector may be a color sensor trained to detect a color of the first web, a luminescence sensor trained to detect a luminance of the first web, or a light-sensitive sensor trained to detect a difference in light passing through the first web. Also, a luminescence additive may be joined with the lower web to provide a distinct luminance.
