A first web is fed over a rotating thermoforming drum which vacuum forms a plurality of pouches for receiving a product to be packaged, and a second web, maintained under constant pressure, is progressively disposed in sealing relation to the peripheral edges of the formed pouches in the first web as the pouches approach a vertical position while the product is simultaneously introduced into the progressively formed package at a rate not exceeding the volume of the package as it is formed.
