Unlike vinyl records, which can suffer "expansion warp" at higher
(which is essentially uncorrectable), shellac records warp (correctably) due
the fact the material becomes soft, and thus flexible, when warm. If the
are tightly packed in their containers (a necessity for shipment in any
they cannot bend and thus will not warp. I would doubt that the temperature
inside a truck box would (or could) reach a point where the shellac
melts and begins to flow...
