Bursting Strength Tester – Prevent Package Rupture & Reduce Losses

The bursting strength of packaging materials directly impacts product safety and loss during storage and transportation. Whether it is corrugated cartons, folding cartons, or flexible packaging composite bags, insufficient bursting resistance makes them prone to rupture under external forces such as stacking and impact, leading to damage to the contents. Therefore, a precise and stable Bursting Strength Tester is an indispensable professional instrument for quality control laboratories in packaging enterprises and third-party testing institutions.

The Bursting Strength Tester (also known as a Burst Tester) is mainly used to determine the maximum pressure, applied perpendicularly to the specimen surface at a uniformly increasing rate per unit area, that paper, paperboard, corrugated board, aluminum foil, and certain flexible composite packaging materials can withstand. The result is expressed in kPa or kgf/cm². The instrument applies pressure to the clamped specimen at a constant rate through a hydraulic or pneumatic system until the specimen ruptures, thereby obtaining critical data such as paper bursting strength or paperboard bursting strength.

The Bursting Strength Tester is not only a requirement for compliance with national standards (GB/T 454, GB/T 1539) and export regulations, but also a practical need to prevent economic losses.

The bursting strength of the liner and facing paper of corrugated cartons directly determines the compression resistance of the carton, while the burst strength of flexible packaging bags affects seal integrity. Without effective testing using a Bursting Strength Tester, batch-to-batch quality fluctuations may go undetected, potentially leading to entire shipments being rejected or claimed due to transport damage, thereby harming brand reputation.

Therefore, whether you are a paper packaging manufacturer, end brand owner, or food/drug flexible packaging producer, equipping a Bursting Strength Tester is a strategic investment to control quality from the source and mitigate risks.
