The envelopes are made using specialized materials that cannot be tampered with without causing visual deformity. Used for preventing unwanted viewing and making certain that products remain protected, the envelopes can be sealed to prevent access to items. The seal on the envelopes cannot be removed without causing damage to the bag. Thus in the event that the bag is tampered with, receivers get a clear indication.
