Bubble cushioning is constructed of pockets of air locked between a top and bottom layer of polyethylene film. for this air bubble cushioning, air bubbles with a bubble height of 3/16” or 1/2" were made. bubble wrap combines the ultimate in protection from shock, vibration and abrasion with extremely light weight. additionally, it is more flexible and resilient than tissue cushioning, and normally thicker than foam. in many cases, less is needed than with other types of cushioning, which results in cost savings. our bubble wrap rolls are perforated every 12 inches for easy tearing and to eliminate hand cutting.
