1. The identification of the hand.
The peritoneal aluminum composite panel is the temperature of the plastic, and the hand feel is warmer; the surface temperature of roll-coated aluminum composite panel is the temperature of the metal, and the hand feel is cooler.
2. Listen to the sound identification.
Lightly hit the center of the laminated aluminum composite panel, the laminated aluminum composite panel will make a dull sound; tap the center of the roller-coated aluminum composite panel, and the roller-coated aluminum composite panel will make a crisper sound.
3. Identify with a pair of scissors.
Look at the edge of the board with a pair of scissors to see if it can be separated. If it is a laminated sheet, the surface film is easily separated by the scissors. If it is a roll-coated sheet, it can't be knocked off with a pair of scissors.
