ABSTRACT Packaging of series of relatively small articles between long webs of wide packaging laminates having faces of resilient heat-sealable foam. One web is fed foam-face-up across a table, the articles to be packaged placed on it in spaced locations, heated melting shoes applied to web edges to melt the foam surfaces there, and a second web applied foam-face-down over the spaced articles and heat-sealed to the lower web at its melted edges. Transverse heat sealing, and severings, are effected between successive articles. The heat sealings can be set by cold pressings. Web backings can be made relatively non- porous to minimize bleed-through of melted foam. Before sealing, sandwiched articles can be pressed between upper and lower resilient fingers to urge articles to level at which they project up as much as they project down, from plane of web edges.
