Aiming at the equivalent thin-wall box,the modal experiments which included different viscous medium,different liquid mass and double-layer plate with different inner plate\'s distance were designed,and the corresponding damping ratios were gained.

In this paper,several liquid direct dyes were applied to dye liner board and their effects were introduced.

Burst strength testing of liner board and the affecting factors of bursting strength were analysed.

The process technology and main equipment for the Desert Willow growing in Inner Mongolia as raw material manufacturing corrugating medium and liner board are briefly introduced and technology parameters and the characteristics of the resultant products are presented.

The paper provides an analytical prediction on the gross profit rate and price trend of pulp, newsprint, linerboard, coated paper, offset printing paper and white cardboard and offers relevant investment ratings.

The purpose of the study is to develop tobacco stalk as a new pulping raw material and produce pulp appropriate for making grade A corrugating base paper and Grade A linerboard with the explosion pulping and to produce qualified kraft envelope paper and fine kraft paper.

The laboratory experiment and production experiment of the application of a new loading material-mineral complex fiber-in bag and kraft test linerboard were carried out and the results show that the mineral complex fiber had a remarkable influence on the physical intensity, smoothness, color and opacity etc.
