A Bursting Strength Tester is a laboratory testing device used to assess the strength and durability of products such as cardboard, paper, fabric, and corrugated boxes. The tester provides a measurement for the pressure it takes to burst the product sample by applying increasing hydraulic pressure from an elastomeric diaphragm until the product sample ruptures. The test will measure the material's resistance to tearing, wear, or pressure while being handled, packaged, or transported. Bursting strength may be an indication of how "good" or appropriate a packing material is when determining a packaging material's characteristics and performance.
A bursting strength tester is a critical quality control tool employed for the determination of the resistance of materials such as paper, cardboard, fabric, and corrugated sheets to bursting under pressure. It measures the maximum pressure needed to burst the sample, which in turn indicates its durability and strength.
The tester is based on the hydraulic pressure principle, in which even pressure is applied through a rubber diaphragm until the material bursts. The value of bursting strength obtained indicates the material's resistance to mechanical stress in packaging, handling, and distribution, maintaining the integrity of the products and structural integrity of the package.
In a bursting strength testing machine, the test specimen is placed between two circular discs in a special fixture. The test specimen is then subjected to hydraulic pressure through a flexible rubber diaphragm, taking up the hydraulic pressure uniformly and, thereafter, elongating the material to the point of bursting. The highest pressure that is recorded at the point of the specimen bursting is the bursting strength of the material.
Here are the benefits of the Bursting Strength Tester explained in detail:
Maintains Material Quality
The Bursting Strength Tester assists manufacturers in evaluating the integrity and uniformity of packaging materials such as cardboard and paper. Through their pressure resistance, it ensures that only high-quality, dependable materials are utilized for manufacturing, reducing failures and optimizing overall product performance while being handled and transported.
Minimizes Product Damage
Through testing the bursting strength of packaging materials, companies can make boxes or containers capable of withstanding mechanical pressure. This minimizes bursting, tearing, or crushing during transportation, ultimately preventing damage to products and enhancing customer satisfaction by ensuring goods arrive safely and undamaged.
Facilitates Cost Efficiency
Pre-production testing of materials prevents expensive packaging failure. The Bursting Strength Tester facilitates proper material grade selection, minimizing rework and waste. It guarantees packaging strength compliance without unnecessary consumption of resources, resulting in optimal costs and raw material utilization.
Supports Quality Control Compliance
The tester assists manufacturers in fulfilling national and international packaging regulations by delivering accurate bursting strength results. It ensures quality norms compliance, adds value to the brand reputation, and offers credible information for audits, certification, and customer assurance of product durability and safety in transit.
Here are the applications of the Bursting Strength Tester summarized in detail:
Paper and Packaging Industry
In the paper and packaging industry, the digital Bursting Strength Tester measures the strength of paper, paperboards, and corrugated boxes. It validates that the materials are capable of resisting external pressure while packaging, storing, and transporting, thus avoiding bursts and guaranteeing the safe arrival of goods to consumers or retailers.
Textile Industry
In the textile industry, this tester measures the bursting strength of fabrics, leather, and plastic materials. It measures the resistance of the fabric against rupture when subjected to stress, with manufacturers ensuring quality control, durability, and performance levels in garments, upholstery, industrial fabrics, and all other textile-based uses.
Plastic and Flexible Packaging Industry
The testing device is used to test films, laminates, and plastic sheets in flexible packaging. This is to be sure that the materials used are structurally sound and will not burst while they are being filled, sealed, or transported. This keeps all packaged products safe from intrusion, leakage, and/or contamination.
Corrugated and Carton Manufacturing
Corrugated carton and box producers employ the Bursting Strength Tester to inspect the strength and load capacities of packaging materials. It allows for the selection of boxes for different shipping and storing conditions, so that the package remains undamaged by compressions, handling pressures, and stacking forces.

We all know that friction testing is considered to be a crucial aspect of quality control, especially in the case of flexible packaging films. The co-efficient of packaging can significantly impact how easily the package will slide or move during transit. A low COF can cause the package to slide too easily, risking damage to its contents. Conversely, a high COF can make the package difficult to handle, potentially causing delays.
