A PET backlit film made for super-thin lightbox systems — the edge-lit frames retail and transport specify now. It carries dense, saturated image on a dimensionally stable PET base.
For distributors, importers and wholesalers only — we do not sell to end users.
Slim edge-lit lightboxes are unforgiving: the light travels sideways across a very short depth, so any media that stretches, ripples or blocks light shows every flaw. PET Backlit Film is built for that geometry — a stable PET base that stays flat in the frame and holds saturated colour under transmitted light. It is the media that makes the thin-lightbox category work.
Slim edge-lit frames are replacing deep lightboxes in retail and transport. The media sells with every unit.
Thin frames expose ripple and stretch. A stable base is the difference between a premium display and a returned job.
Backlit artwork lives or dies on density. This is where the customer can see the quality difference immediately.
