The amount of formaldehyde.

The thickness of the laminate directly affects its durability and resistance to shock load. The thicker the sheet, the stronger it is. Moisture resistance is an important quality that is better not to neglect, since it is impossible to repair a laminate. And finally, the amount of formaldehyde in the laminate should not exceed safe norms. For example, a certified Kaindl laminate is marked by E1. And his Chinese analogues are unlikely to have this mark that says that the flooring is safe even for children.
