How do peppers stay firm?
Utah State notes prepackaging peppers in plastic film helps retain moisture plus can extend storage life up to a week beyond unpackaged fruit. It advises cutting fruit from the plant with a one inch stem, though careful twisting also works.

Troubleshooting
Wrinkles on the plant: uneven soil moisture. NC State advises even moisture.
Soft fruit in storage: too warm. Utah State notes warmth above 55°F speeds soft rot.
Damage after cold storage: chilling injury below 45°F, per Utah State.
