1. Gently separate: First, try to gently separate the leather bag from the mineral water bottle. Try using some lubricant, such as olive oil or vaseline, and then gently try to separate the two.

2. Cooling method: put the glued leather bags and mineral water bottles in the refrigerator for a period of time, and use the principle of thermal expansion and cold contraction to reduce the shrinkage of plastic bottles, thus reducing adhesion.

3. Blower: Heat the bonding place with a blower to melt the plastic at the bonding place, and then dry it with a paper towel.
