Paper and board testing standards and methods

Paper and board testing

The paper, cardboard and printing industries have more and more requirements for the performance of raw paper. TTS Lab has independent 25 square meters Constant temperature and humidity test room (maintain temperature 23 °C , humidity 50% RH ), provides a stable working environment for material testing, provides all testing items, analyzes the performance indexes of raw paper according to GB , HG , ASTM , ISO , JIS , TAPPI and other standards to provide enough for your production. Guarantee. For the user, the quality of the paper for life and culture will affect the quality of life or work. TTS provides effective inspection data for the technical supervision department, which provides a high degree of protection for the merchants to integrate the suppliers.
