What is the direct relationship between bursting strength and compressive strength of cartons?

The factors affecting the compressive strength and stacking strength of cartons are analyzed from the following five aspects: 1, raw material quality; ? Base paper is the decisive factor to determine the compressive strength of cartons, which can be seen from kellicutt formula. At the same time, the influence of other conditions in the production process of corrugated board, such as adhesive dosage, impregnation, coating and composite processing, can not be ignored. 2. Corrugated board with high water content for moisture-proof cartons, or stored in a humid environment for a long time, will also affect its compressive strength and stacking strength. 3. Box type specification refers to the type of box and the size ratio of the same type of box, which also has obvious influence on compressive strength and stacking strength. The compressive strength and stacking strength of cartons made of different layers of corrugated cardboard are also different. Under the same conditions, the higher the box, the worse the stability, and the lower the stacking strength and compressive strength. 4. Printing and punching printing will also reduce the compressive stacking strength of cartons. This is because punching holes on the surface of the box or punching holes on the side of the box will reduce the compressive stacking strength of the carton, especially when the hole area is large and biased to one side. 5, processing technology deviation; Generally, you need ink printing slotting machine, and you need to determine several colors according to the box you make, because the printing requirements, configuration and materials are different. The general price is 500,000-500,000. For export cartons, 20,000 thin knife machines are optional, and one box nailing machine is enough. Generally, it is about 65,438+020,000. Improper line pressing, too deep grooving and weak combination will also reduce the compressive strength of the box. If the finished carton needs to reach a certain strength, it must be tested for compression resistance (carton compression tester), stacking, ring pressure, solid pressure, edge pressing, bonding (ring pressure tester) and bursting strength (bursting strength tester) to evaluate whether the carton meets customer requirements or national standards. ?
