Bubbles or edge lift can affect surface coverage and package appearance. Causes can include preparation, application method and film compatibility.
During application
Ensure the surface is clean and dry as required by supplier instructions. Apply the recommended pressure; pay particular attention to samples on textured surfaces and narrow edges.
Track the issue
Record whether lift occurs immediately or after storage. Change one variable at a time when reviewing surface, pressure and environment. Verify suitability with the supplier before reapplying.
