The terms “film” and “sheet” are often confused with each other, as they are sometimes used interchangeably. Although both refer to thin, flat materials, they have distinct characteristics and applications
Uses and Applications
Broadly, three major markets exist for films:
- Packaging: Encompasses applications like food wraps, bags, and other packaging solutions.
- Industrial: Includes diverse uses such as tapes, photographic film, and various industrial applications.
- Soft goods: This category covers items like raincoats, shower curtains, and upholstery materials.
In the case of sheets, thinner gauges find their primary application in thermoformed food packaging. Beyond food packaging, thinner sheets find diverse uses in:
- Stationery and office products: Creating lightweight, durable folders, dividers, and presentation materials.
- Tanks, ducting, and industrial applications: Offering a combination of strength, formability, and chemical resistance for various industrial needs.
Classifying film and sheet based on thickness
Specifically, differences between films and sheets are related to their technical characteristics. Films typically measure less than 0.25 mm (0.01 inches). While Sheets exceed 0.25 mm in thickness. In some industries, 0.004 inches (0.10 mm) serves as the dividing line between film and sheet.
In conclusion, the easiest way to differentiate is: Sheets are typically sturdier and used for applications requiring rigidity and durability, while films are commonly used for packaging and wrapping due to their flexibility.
