Abstract: Heat shrink wrap product packaging oven or tunnel apparatus and processing methods are provided which incorporate or utilize airfoils in conjunction with hot air-providing side walls to desirably control impact of hot air onto a product wrapped with a tube of heat shrink wrap film and being conveyed on a conveyor thereby. In such heat shrink wrap product packaging apparatus and methods, such airfoils can be movable, e.g., rotatably moveable, relative to the side walls to vertically alter an air impact point onto the product.
