Bursting Strength Tester | High-Accuracy Paper & Packaging Strength Testing Machine

A Bursting Strength Tester is a precision testing machine used to determine the maximum pressure that paper, cardboard, packaging sheets, laminated board, and other flexible materials can endure before they rupture. It is one of the most essential quality-control instruments for industries like packaging, printing, paper manufacturing, logistics, and corrugated box production.

The tester works by applying uniform hydraulic or pneumatic pressure on a clamped sample until it bursts, accurately recording the highest force applied. This test helps manufacturers evaluate material durability, compare quality grades, optimize packaging design, and ensure that materials comply with global standards during stacking, transport, and load-bearing conditions.

Core Purpose & Applications

• Bursting Strength Testing – Measures rupture pressure for paper, cardboard, kraft board, and packaging sheets

• Quality Assurance – Ensures compliance with ISO, ASTM & TAPPI standards

• Material Innovation – Helps in R&D for paper mills and packaging developers

• Packaging Optimization – Ensures safe carton design and material selection

• Industrial Safety Compliance – Validates strength for transport, handling, and storage
