Abstract: A packaging method and apparatus employ web material having cohesive on facing surfaces of two web portions between which an item is packaged. The cohesive adheres to itself by application of pressure alone, without heat, but tends not to adhere to other surfaces. The web portions are sealed together about the item by seal devices that apply pressure without heat to the web portions. The web portions and item can be passed through a resilient nip formed by two rolls, at least one of which has resiliently compliant roll portion(s) for pressing the web portions closely about the item.

Abstract: A system for heating and dispensing foam-in-bag packaging bags comprises a housing that rotatably supports a roll of a continuous web of interconnected foam-in-bag packaging bags, and at least one heater for heating bags to an elevated temperature prior to the bags being dispensed from the housing. A heated bag is dispensed and is detached from the web, and is then manipulated to mix foam precursor chemicals contained in separate compartments in the bag to begin a foam-forming reaction in the bag.
