Abstract
PURPOSE: To eliminate slacks appeared at the edges due to moisture absorbing, by heating up the surface of a thick polyester film within a specific temperature range.
CONSTITUTION: When polyester films or their products with a thickness of 50μ or more are rolled or piled up for a long time and then they are spread out to sheets, slacks always appear at the both edges due to moisture absorbing. In this case if the surface of the film is heated at a proper temperature in a range of 50W130°C, thermal strain can be eliminated because difference of moisture rates at the edge and the center in the direction of the width is kept at 0.05% or less. As a result, a sheet having high surface characteristics which prevent dislocation during a secondary operation such as printing, coating, drilling, or cutting, is obtained.
