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…

To ensure that paints and coatings are easy to apply and durable in their nature, oils and additives are required. To know that the addition of these components doesn’t adversely affect the composition of your final paint or coating, you need thorough and efficient viscosity testing. Oils and lubricant additives in paint The addition of…

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…
Paper & Corrugated Packaging Color Measurement Glossary Brightness (ISO) A measure of the reflectance of paper or board at 457 nm blue light, expressed as a percentage. Governed by ISO 2470-1. Higher brightness values indicate a whiter, cleaner-looking sheet. Standard instrument geometry: d/0°. CIE (International Commission on Illumination) The international body that defines standardised color scales and measurement…
Overview: How to Measure Color Consistency Color consistency is one of the most commercially sensitive quality parameters in paper and corrugated packaging production. Whether you are a paper mill supplying liner to a converter, a corrugated board manufacturer running print lines, or a brand owner specifying packaging, color that drifts between batches or production runs…
Color Consistency in Paper Packaging Color consistency is the ability to reproduce a defined, measurable color repeatedly and accurately across a production run, across substrates, or across multiple production sites. In paper and corrugated packaging, it is a critical quality parameter that directly affects brand integrity, print quality, and customer acceptance. For converters, brand owners,…

What is the purpose of the Technidyne paper calibration standards? To ensure the accuracy of your paper and pulp tests, in line with national and international testing standards, and to ensure the accuracy and verification of your instrument’s…
The weight of paper or card tells you a lot about its other properties, making paper weighting and grammage testing a must for all paper mills and flexible packaging manufacturers. Paper weight is normally recorded as a number of grams per square meter and expressed as either gsm or g/m2. It can also be expressed…
When you need details on contamination, adhesion, surface energy, and printability of a surface, a goniometer could be just the test and measurement solution you need. These handy devices offer a non-destructive testing method that measures the contact angle of a droplet on a surface to determine a number of important material properties. What is…
