Two primary manufacturing processes differentiate vinyl films: casting and calendering. Casting involves pouring liquid vinyl onto a flat surface, allowing it to cure into a thin, consistent sheet. Calendering, conversely, uses rollers to press vinyl resin into sheets, a process involving heat and pressure. This fundamental difference in production leads to distinct characteristics in the final product, impacting durability, flexibility, conformability, and application suitability.
The distinct properties arising from these manufacturing methods influence material selection for various applications. Films created through casting exhibit superior dimensional stability and are less prone to shrinkage or distortion, making them ideal for demanding applications like vehicle wraps or high-resolution graphics. Calendered films, while generally more economical, offer good performance for less demanding applications such as flat surfaces or short-term signage. Understanding these inherent differences ensures appropriate material selection, optimizing project outcomes and maximizing return on investment.
