What causes the black paper in the film packet to become stuck to the film?
What will be an ideal response?
A tear or break in the outer protective wrapping of the film packet enables saliva to penetrate to the emulsion, causing the paper to stick to the surface of the film. Moisture softens the emulsion, causing the black paper to stick to the film. Careful handling prevents a break in the seal of the film packet.
