What is the difference between vinyl and film when working with heat transfers?
The words “vinyl” and “film” are both commonly used when referring to heat transfer material. Although these terms are often used interchangeably, there is a distinction. Technically, vinyl implies a polyvinyl chloride (PVC) composition, which is not safe for use on children's wear or laser cutting. Vinyl can have a negative connotation to consumers, as well as being an “old school” reference.
While heat transfer vinyl has become somewhat of a generic classification, there are relatively few of these materials today that are truly vinyl. This makes the terms “film” or “flex” more accurate and less pejorative alternatives for describing them.
