Our exclusive Heritage Corrugated Board sets the standard in the next generation of archival corrugated board. Greatly exceeding the quality of other boards available on the market today, and passing much more stringent testing for permanence than simply the Photo Activity Test, this is the next generation board.
This multi-use board is blue/gray on one side and white on the other, making it perfectly suited for framing, box making, and other types of enclosures where the objects can sit against a non-pigmented surface, while still maintaining the traditional blue/gray color on the outside.
