Abstract:
Air leaks in a seal beneath a vacuum bag are detected using a leak detection film inside the vacuum bag. The film includes a gas permeable binder and a gas sensitive material held in the binder. The gas sensitive material has at least one visual characteristic that changes in the presence of gas entering the vacuum bag through a leak in the seal.
