Provides a method of protecting a Low-E glass sheet that prevents or inhibits deterioration of the Low-E layer. Provides protection for Low‑E glass panels. The protection method is a method of protecting a Low-E glass plate: a protection sheet having a base material and an adhesive layer provided on at least one surface of the base material is attached to a material containing a zinc component through the adhesive layer. The Low-E layer of the Low-E glass plate is thus protected. This method is characterized in that, as the protective sheet, the pressure-sensitive adhesive layer is formed of a water-dispersed pressure-sensitive adhesive composition, and the ammonia content of the pressure-sensitive adhesive layer measured by hot water extraction is relative to the pressure-sensitive adhesive layer. The weight of the protective sheet is less than 850μg/g. |
