An envelope tray adapter is designed to protect a horizontal stack of envelopes positioned in a postal tray having outwardly angled sidewalls. The adapter has pairs of side and end panels joined end to end and sized to fit on the bottom wall of the tray. Each panel has a height greater than the envelope stack, but less than the sidewalls of the tray for supporting a second postal tray nested on top and protecting the envelopes from crushing. The panels may be formed from a continuous length of material that is folded to form the end and side panels. The adapter panels may also be formed of a corrugated paper material. One end of the panels has a free end including a glue flap that overlaps and adheres to the inner surface of the adjacent panel.
