Abstract
The invention relates to liquid board comprising one or more layers of material containing cellulose, one or more of said layers comprising an additive that has the capacity to react with or decompose a disinfectant with which said liquid board is treated, so that a gas is formed that acts as a barrier and thereby prevents the penetration, especially edge penetration, of said disinfectant into the paperboard layer/layers.
