What is the difference between PUR edge banding and laser edge banding?

You can tell the difference by looking at three things: whether the glue line is obvious, whether the edges easily absorb moisture and swell, and whether they warp after prolonged use. PUR edge banding uses a reactive adhesive and performs well in water resistance and temperature resistance; laser edge banding has almost no glue line and looks cleaner. Both can be done; when choosing, consider your budget and the humidity of the space.
