Overview Burst strength testing is one of the most widely used methods for evaluating the performance of sealed flexible packaging. It applies controlled internal pressure to a package until failure, measuring the point at which the seal or material gives way. For quality managers, R&D specialists, and operations experts working across flexible packaging production, burst…

Definition: Wet coating thickness measurement is the process of measuring the thickness of applied coating or paint layer immediately after it has been applied to a metal coil substrate — before the coated product enters the curing oven and dries. This is achieved using non-contact, optical sensor-based technology positioned inline at the point of application. Why it matters: In coil coating production lines, coatings travel at high…

Color consistency in metal can manufacturing refers to the ability to reproduce a brand's specified colors accurately and repeatedly across every decorated aluminum or steel beverage can - regardless of production run, facility, or geography. In the can-making industry, color is measured using three attributes: hue (the recognized color, such as red or blue), chroma (the vividness or saturation of that color), and lightness (how light or dark the color appears). These are quantified using…

Definition Fiber tensile strength describes the maximum pulling force a pulp fiber network or paper sheet can withstand before breaking. It is one of the most important mechanical properties in paper and pulp manufacturing, directly influencing how well finished materials perform under real-world stress. For paper and handsheet testing, tensile strength is typically reported in kilonewtons per meter (kN/m)…
Zero-Span Tensile Testing overview Zero-span tensile testing is the industry-standard method for measuring the intrinsic strength of individual pulp fibers within a paper sheet. Unlike conventional tensile tests - which measure the combined effect of fiber strength and inter-fiber bonding - zero-span testing isolates fiber wall strength by gripping the sample at a gauge length of zero…
Key terms, definitions, and facts for fiber strength and material performance testing in paper and pulp manufacturing. Key Terms Zero-Span Tensile Strength The breaking strength of a paper sample measured at zero (or near-zero) gauge length. Isolates the intrinsic tensile strength of individual pulp fibers from inter-fiber bonding effects. Measured to TAPPI T231. Expressed in kN/m or as…
Whether you're testing the peel strength of a pharmaceutical blister pack, the tensile properties of a flexible film, or the compressive load bearing of a structural component, the Universal Testing Machine (UTM) is one of the most essential instruments in your quality and R&D toolkit. Used across industries from packaging and medical devices to automotive and aerospace, UTMs…
UTM Key Terms: Glossary & Fact Sheet A quick-reference guide to the most important terms in Universal Testing Machine (UTM) operation and materials testing. For a full explanation of how these terms are applied in practice, see our Test Method Explainer. Load frame The structural component of a UTM that houses the crosshead, columns, platens, and drive system. Designed…
Universal Testing Machine (UTM) A Universal Testing Machine (UTM) is a precision mechanical testing instrument used to measure the physical properties of materials, components, and finished products under controlled tension, compression, flexure, peel, and shear forces. The term "universal" reflects the machine's ability to perform a wide range of standardised tests on a broad variety…
Burst strength testing in flexible packaging is the process of applying increasing internal pressure to a sealed package until it fails - measuring the maximum pressure the package can withstand before rupture. It is a fundamental method for evaluating seal strength, material performance, and overall package robustness. Where leak detection identifies defects that already exist…
