Dynamic Strain Rate Modeling for Multi Ply Boxboard under Rapid Compression
Dynamic strain rate modeling predicts multi-ply boxboard Z-direction compression and interlayer shear collapse during high-speed converting and package drops.
Packaging Impact Test
Dynamic Assessment
Verifying the durability of a fully loaded shipping container under sudden mechanical shocks is required to ensure product safety during distribution. The packaging impact test measures the ability of the combined board to withstand sudden decelerations. This evaluation provides the data needed to optimize protective packaging designs.
Simulation Procedure
Performing this evaluation involves subjecting the packaged product to controlled drops or horizontal collisions. The packaging impact test utilizes specialized equipment, such as drop testers or inclined ramps, to replicate the forces experienced when a carton falls from a delivery truck or slides against a railcar wall. These instruments are calibrated to deliver a precise amount of kinetic energy to the specimen.
This structured testing helps engineers identify the weak points in the outer box and the internal inserts.
Failure Evaluation
Analyzing the results of the shock allows technicians to determine if the protective elements have performed as intended. The packaging impact test looks for damage to the product, such as deformation or breakage, and signs of structural failure in the paperboard carton. If the packaging fails, the designer can adjust the board grade or change the cushioning material to increase shock absorption.
This continuous refinement ensures that the finished pack can survive the hazards of the logistics chain.
