Abstract
An inflatable web (10) includes a top film (30) heat sealed to a bottom film (32) to define sealed regions (40) and non-sealed regions (214). The non-sealed regions include inflatable regions (216) that are inflatable through one or more inflation ports. The top film (30) may have a color that differs from the color of the bottom film (32) to create a visual contrast between the sealed regions (40) and the adjacent non-sealed regions (214) when the web is viewed from the top film side. The ratio of the surface area of the inflatable regions (216) to the total surface area of the inflatable web is at least 50% and at most 95%.
