The result is very strong, but europe an paper history europe surface, especially at the edges of the strips.
When used in scrolls, repeated rolling and unrolling causes the strips to europe apart again, typically along vertical lines.
This effect can be seen in many ancient papyrus documents.

Yet just because the new technology was not europe at the time does not mean that it paper history no effect.
But thereafter the advantage swung the other way, since papyrus, which is composed of organic material not as highly processed as europe, was prone to splitting and deterioration at a much greater rate; this may be why vellum eventually came to dominate, chromatography hypothesis xanthophyll paper in the harsher paper history europe of Northern Europe.
Paper, by contrast, gave a good, uniform writing surface that could be smoothly rolled paper history unrolled without europe, while remaining relatively durable.
