Abstract
A packaging apparatus includes a pair of rolls forming a nip through which two web portions are passed with an item to be packaged between the web portions. The rolls include resiliently compliant roll portions that deform to accommodate the thickness of the item, and the roll portions press the web portions to seal them together in peripheral regions surrounding the item and to center the item between the webs in the thickness direction. The apparatus also includes side seal devices that traverse inwardly toward the item to seal the webs together close to the item's opposite side edges to prevent the item from laterally shifting. The web portions may have cohesive disposed on their facing surfaces such that the web portions adhere to each other with pressure but tend not to adhere to the packaged item or other surfaces.
