Abstract
Abstract This invention is a hang bag and the method for making it. The hang bag is designed to be hung on peg board displays at supermarkets and the bag comprises a non-shrinkable, heat sealable strap across the width of a side seal heat shrinkable bag. After the product has been put in the bag and the bag has been shrunk, the unshrunken strap forms a convenient loop for easy hanging.
