Gypsum board sealing paper is primarily used to secure two sheets of gypsum board together and enhance their overall strength. It also provides identification and aesthetic benefits.
1
Securing and Protecting
Block paper bonds the ends of two gypsum boards together, creating a stable structure similar to a pair of chopsticks. This prevents breakage caused by the fragility of the individual sheets during handling or installation.
2
Strength Enhancement
Approximately 80% of gypsum board's strength comes from the cover paper (also known as the cover paper). By tightly bonding with the gypsum crystals, it significantly enhances its flexural and tensile strength.
3
Identifying and Beautifying
Block paper often features brand logos or advertising information, making it easier to distinguish between products and enhancing visual appeal.
