How can PUR edge banding and EVA edge banding be distinguished with the naked eye?

EVA edge banding has a visible glue line and tends to come unglued when heated; PUR edge banding has a fine glue line, resists heat and moisture, and is not prone to peeling over long-term use. The workshop has samples of both types of edge banding for on-site comparison, and the contract will specify the edge banding process to avoid substitution midway.
