Crush strength tester-Another side of the paper

Paper and cardboard are an important packaging material in the packaging industry. The manufactured cartons have good rigidity, strength and cushioning properties. With the advantages of environmental protection, low cost, easy storage and transportation, etc., they have gradually replaced wooden boxes and other packaging. Containers have become the main force in transportation and packaging.

Compressive strength is the maximum pressure that a material can withstand after being compressed to crushing. It is an important performance index of white paperboard and corrugated paperboard. It can reflect the comprehensive characteristics of the entire box-making process and the inherent strength quality of the carton. Among them, ring compressive strength, flat compressive strength, and edge compressive strength are indicators of the compressive strength of paperboard.
