Abstract
A carrier for use in a pneumatic tube transport system includes first and second shell members, at least a first hinge for pivotally interconnecting the first and second shell members such that the shell members can move relative to one another between open and closed positions, and at least a first seal band interconnected to at least one of fore and aft portions of the first and second shell members. At least the first seal band includes a plurality of fibers mountable on a first backing strip, the fibers having a modulus of elasticity of at least about 1.times.10.sup.5 psi, being mounted perpendicularly relative to the first backing strip, and uniformly distributed on the first backing strip.
