Testing of paper and cardboard
[Project Introduction]
The papermaking industry, paperboard industry and printing industry have increasingly higher requirements for the performance indicators of base paper. TTS has an independent 25-square-meter laboratory with constant temperature and humidity (maintaining 23℃ and a relative humidity of 50%), providing us with a stable working environment. All the test items we can provide are analyzed in accordance with standards such as GB, HG, ASTM, ISO, JIS, and TAPPI to assess the performance indicators of the base paper and provide sufficient guarantees for your production. The quality of paper applied in life and work is closely related to the quality of our life and work. TTS will provide your technical regulatory authorities with effective test data and offer more effective guarantees for users to select more suitable suppliers.
