All About SubstratesWe carry a wide variety of white & clear, metallic, and specialty substrates. Most are vinyls (PVC) and polyesters (PET), with some BOPP & Paper. Contact your Custom Label Specialist to find out what would be the best for your application.
- Low Temperate Resistance, generally less brittle at lower temperatures than other substrates
- Good UV Resistance, Vinyls hold up well to UV in outdoor applications.
- Conformable, works good for curved or irregular surfaces.
- Good Printability, Generally has the best printability with most print processes.
- Shrinks, especially when printed with solvent inks, slight shrinkage to be expected and can be compensated for, always test for tolerant critical applications.
Cast VinylsCast vinyls are poured into a cast or mold. Cast vinyl is generally thin 2-3 mil (0.002” – 0.003”). Cast vinyl will generally have little shrinkage and very good conformability. Calendared Vinyl is extruded and calendared down to the appropriate thickness. Calendared vinyl is generally 3-5 mil (0.003” – 0.005”).
Calendared VinylsCalendared vinyls generally tends to shrink more but are less expensive than cast vinyls. Calendared vinyls tend to shrink more one direction then the other and will shrink more when printed with solvent based inks.
- Dimensionally Stable, does not stretch or shrink.
- High Temperature Resistance, can withstand higher temperatures generally than vinyls.
- Inert, is less reactive with chemicals than vinyl generally is more chemically resistant
- Rigid, is generally more rigid than vinyl and doesn’t work on curved surfaces as well and will not work on compound radius surfaces.
- Less Conformable, doesn’t work on curved surfaces as well and will not work on compound radius surfaces.
- Less Printability, isn’t as printable as vinyl, solvent inks will not print on polyester and most print processes perform better on vinyl.
Polyester substrates are very rigid and inert. Polyesters are generally easier to handle and apply than vinyls of the same thickness. Polyester is a good outdoor durable product but is generally not as outdoor-durable as vinyl. Polyesters have slightly better chemical resistant properties than vinyl and also the white polyesters have a “pearl” appearance. Polyesters are not conformable and are not recommended for curved or irregular surfaces. Polyester has good abrasion resistance and dimensional stability. Polyester is good for dimensionally critical labels. Polyester is not printable with solvent inks. Most metallic substrates are polyester.
