Abstract
A food product package includes a bulky food product hermetically sealed in a bag of heat shrunk film. The package has an integral self-supporting handle which is formed from plies of the film and which extends out from an end of the package in a conventional handle shape. The handle is formed by causing a skirt portion of the bag to heat shrink about a rigid member positioned to maintain the skirt portion spaced from an end of the package during shrinking.
