(1) Using instant-coated film as a cover protects the paper. Lamination extends the lifespan of the cover (or printed surface), which is particularly beneficial for student textbooks, leading to its increasing use.
(2) Imprints are less likely to be damaged. Instant-coated film enhances the color effect and protects color-printed graphics from wear. This allows publishers' graphic designers to create various artistic designs on the cover or printed surface according to their needs, further driving up usage.
(3) Instant-coated film production is highly profitable. Instant-coated film production is low-cost, easy to implement, and profitable, allowing companies to profit.
These three points have made instant-coated film popular, but the quality problems it presents and its impact on binding quality have received little attention. This will be further analyzed below.
