Series 3210: 1.3-mil, most conformable, softest of the three, when paired with SLX it drapes better and allows for easier "cold" stretch during installation (GLOSS ONLY) Series 3220: 2-mil, conformable, softer than 3270 so FLITE won't slide as easily, but will "cold" stretch better than 3270 Series 3270: 2-mil, same conformability as 3220, stiffest cast overlaminate which allows for SLX to float over the substrate
Series 3210: This is the thinnest overlaminate we offer at 1.3-mil. When paired with SLX, it allows for the best "cold" stretch of the film during install. This film is most ideal when paired with DPF 6700 installed over textured surfaces.
Series 3220: This is our standard 2-mil overlaminate and is a good middle ground between 3210 and 3270. It does some "cold" stretch and can prevent stretching during installs of large panels. It is less stiff than 3270, but more stiff than 3210.
Series 3270: Standard 2-mil overlaminate that was designed to be used with SLX to give it a board-y feel(stiffer) that allows it to slide most easily over a surface. This is the stiffest of our cast laminates and its benefits are mostly seen when doing large panels (such as side of trailers or box trucks) where it retains the shape of the graphic during installs and prevents the vinyl from stretching.
