Introduction to the determination method of cardboard burst resistance

NPD-D paperboard burst resistance tester is the basic instrument of paper and paperboard strength performance testing, its performance parameters and technical indicators in line with ISO2759 "paperboard - damage resistance determination", GB1539 "paperboard burst resistance determination" and ISO2758 "paper-break resistance determination" and GB454 "paper breakage resistance determination" and other standard provisions and requirements, suitable for all kinds of paper and paperboard burst strength test
.
The instrument is simple to operate, reliable performance, advanced technology, is the ideal equipment
for scientific research, paper manufacturers, packaging industry, quality inspection department.

Quality: 65kg National standard: ISO2759, GB/T1539, ISO2758, GB/ T454 label: The burst resistance of cardboard tester corrugated cardboard has a close relationship
with the breakage resistance of boxboard (corrugated base paper), the thickness and bonding strength of corrugated cardboard.
It can be considered to be the sum of the burst resistance values of each layer of paper, it is a recognized performance index of great significance, to improve the burst resistance of corrugated cardboard, the quality of the base paper and the production process
of corrugated cardboard should be strictly controlled.
