Unwind force is the spec nobody writes down

Most carpet film specifications list width, thickness and length. Very few list unwind force — the effort it takes to pull the film off the roll — or the window in which the film can be removed cleanly. Those two numbers decide whether the installer finishes the room or fights the roll.

When we looked at public reviews of carpet protection films, the most common complaint was not adhesive left on the carpet. It was film that grabbed itself, tore at the edge, or became impossible to lay flat. Residue came fifth.

The fix is not “more tack” or “less tack”. It is a specified range: a peel value that holds the film down without welding it to the pile, and a removable window that matches the job. A two-week fit-out and a six-month renovation are not the same film.

If you buy carpet film, ask for three things: the peel range, the removable window, and the unwind force. If a supplier cannot give you those numbers, they are selling you a roll, not a specification.
