Abstract
A method for packaging a product includes the steps of providing a composite film including a non-barrier layer and a peelable barrier layer; providing a bottom web having the product supported thereon; removing a strip of the non-barrier layer from an edge of the composite film so as to provide an extending portion of the barrier layer which extends beyond the non-barrier layer; and sealing the composite film over the product to the bottom web so that the non-barrier layer overwraps the product and is sealed to the bottom web wherein the extending portion of the barrier layer forms a pull tab for peeling the barrier layer from the non-barrier layer.
