In some embodiments, a molding packaging material includes an outer side base layer made of a heat resistant resin, an inner sealant layer, a metal foil layer arranged between the outer side base material layer and the inner sealant layer, and a matte coat layer formed on a side opposite to a metal foil layer side of the outer side base material layer. The scan test architecture provides a method of performing scan test of unbalanced scan chains. The first and second side panels of the tunnel each include a running board supported by the steering hoop structure. The respiratory mask may also include an external shield to enhance sealing and provide a barrier of protection for the healthcare provider.
