A plastic bag, glued to the inside of a carton during manufacture, provides the required separation of an in situ foamed cushion from the product packaged by the foam. This saves time and eliminates problems encountered in handling a separate sheet of plastic. Fig. 1A shows plastic bag 10 hanging inside carton 20, as it appears after the carton is opened. The edges 30 of the bag are glued to the edges of the upper flaps of carton 20. Fig. 1B shows that the edges 30 of bag 10 may be pleated at the point of attachment to carton 20. The bag is slit at the four corners, the width 15 of the upper carton flaps, to permit the flaps to be freely opened and closed. Fig. 2A shows carton 20 inverted over product image 40 on work table 50 with bag 10 loosely draped over product image 40.
