In the soundproof room of our company's corrugated cardboard line, the ambient noise has been reduced from about 110 decibels to about 80 decibels, and the workshop temperature can be reduced by about 8 to 10 degrees.
Zhejiang Ningbo Rihe New Material Packaging Co., Ltd. will launch a new BHS 2.8-meter five-layer corrugated cardboard line project in 2022, and installed our company's first set of soundproof rooms. Due to the remarkable noise reduction and sound insulation effects, their company has recently installed them continuously. 7 sets of corrugated cardboard line soundproof rooms were built.
