Common questions about FreePost® AC
Q1What printers and inks is FreePost® AC series PET film compatible with?
FreePost® AC series is designed for desktop water-based (aqueous) inkjet printing. Its coated PET face accepts dye and pigment water-based inks, making it suitable for desktop inkjet printers used in offices, photo labs and small-format sign shops.
Q2Is FreePost® AC film removable without residue?
The AC series uses a strong adhesive layer for secure, long-term bonding on clean flat surfaces rather than a low-tack removable adhesive. For guaranteed residue-free removal, choose the gecko-toe WALLIZARD®, vacuum Easy Cling™ or dot-adhesive Spider™ series instead.
Q3Can FreePost® AC series be used outdoors?
Selected AC models are rated indoor & outdoor. The series offers good dimensional stability and weather resistance with a waterproof coating, supporting short- or long-term use depending on the model — check each model's indoor/outdoor rating in the catalogue.
Q4Is FreePost® AC series PVC-free?
Yes. FreePost® AC series films are PET-based and PVC free, making them an environmentally friendly alternative to vinyl for window stickers, decorative stickers and sign stickers.
