Large blow molded objects are produced by extruding a generally tubular form in a horizontal direction so as to form a large pillow shaped object upon sealing. The sealed pillow shaped article is severed and conveyed to a mold having a predetermined configuration and blow molded into a desired shape. The horizontal production of the parison used for blow molding permits the production of large parisons without the sag associated with a vertical process and also permits continuous coextrusion of large parisons without the need for complex accumulating equipment.
