Carrier Sheet

A carrier sheet is the clear polyester film laminated to the face of HTV before it ever reaches a cutter, and on printed transfers it plays the same role from the other side. For vinyl, the cutter plots the design through the colored film while it's still stuck to the carrier, and after weeding pulls away every scrap that isn't part of the design, the carrier is what keeps the remaining letters or shapes from scattering.

Anyone handling a raw HTV design or an iron-on transfer at home is working with this sheet directly, laying it face-down against the garment, checking alignment through the clear film, and peeling it back once the press has bonded everything underneath. Multi-letter names and numbers depend on it entirely, since without the carrier holding spacing, an M and a 7 cut separately would have no way of landing in a straight line.

Whether the carrier peels while the garment is still hot or after it cools depends on the specific vinyl or transfer, and pulling it at the wrong time is the single most common reason a fresh press looks perfect and then fails: letters lift with the carrier, edges curl, or the adhesive hasn't fully set yet. Pros always check the roll's spec before touching the peel.

New buyers sometimes treat the carrier sheet as disposable packaging and peel it off the moment the press opens out of habit, but on a cold-peel material that's exactly the mistake that pulls half the design away with it. The carrier stays doing its job until the specific transfer says it's safe to remove.
