Peel Test
A peel test is a workshop quality check that verifies window film adhesion by attempting to lift a small corner of installed film; properly cured film resists peeling.
Peel tests are done on test panels during installer training rather than on customer vehicles. The metric is how much force lifts a defined area of film.
Standard adhesives bond strongly enough that a fingernail cannot lift them after cure. Films that peel easily indicate adhesive failure or installation defect.
For Singapore workshops, peel tests are also part of the QC for incoming roll stock — a quick test panel before installing on a customer's vehicle catches batch issues early.
