To uncurl paper, you can try gently rolling it in the opposite direction of the curl and then placing it under a heavy book or object. You can also lightly mist the paper with water and then flatten it out with your hands. Another method is to carefully use a hairdryer on a low setting to warm the paper and help it uncurl.
Is cellophane paper plastic or paper?
Cellophane is a plastic made from paper. The same wood cellulose found in paper is the basis for cellophane. The thin film is "regenerated" from cellulose that has been dissolved in caustic soda, then treated with sulfuric acid.
The same material (called viscose) that forms cellophane is the base for the "semi-synthetic" polyester fiber known as rayon.
When paper becomes wet, the fibers in the paper absorb the water unevenly, causing them to expand and contract at different rates. This uneven expansion and contraction create stress on the paper, leading to curling as it dries.
That is tricky, because most things that will wash ink off will also destroy paper; furthermore, there are many different kinds of inks, having different chemical properties. That said, your best best is to delicately apply chlorine bleach. That might work. No guarantees.
