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…

Can seaming to achieve robust, hermetically sealed metal packaging is a preferred practice to protect a wide range of types of products across many industries. An effective double seam is crucial to the integrity of a can. The process of can seaming has been around for decades and has undergone some massive transformations over the…

Thickness, also called caliper, is the perpendicular distance between the two principal surfaces of a sheet of paper or board, measured under a defined static load between hard metal platens. It's one of the most fundamental physical properties in paper and board manufacturing, and it directly influences strength, stiffness, bulk, and how a material runs…
Thickness, or caliper, is one of the first properties many mills measure, and one of the most revealing. It tells you how much material is in a sheet, and it points to how that sheet will behave under stress, through a press, and inside a finished package. Getting it right is a balancing act between…
Key terms Caliper: Another word for thickness; the perpendicular distance between the two principal surfaces of a sheet, measured under load. Single sheet thickness: The thickness of one sheet of paper or board, measured under a defined static load. Bulking thickness: The thickness of a single sheet, calculated from a pack of superimposed sheets measured…
The neck finish is the topmost section of a plastic bottle or container - including the threads, sealing surface, and opening dimensions. In plastic bottle manufacturing, neck finish quality control refers to the systematic inspection and measurement of these features to verify they conform to specification. Why It Matters The neck finish determines whether a…
Introduction: Small Tolerances, Big Consequences In plastic bottle manufacturing, seemingly minor dimensional variations in the neck finish or body geometry can have significant downstream consequences - from cap incompatibility and leakage to structural failure, line stoppages, product recalls, and lasting reputational damage. As packaging designs become lighter, more sustainable, and increasingly complex, tight, repeatable quality control of…
Key terms and definitions for packaging quality professionals, QA managers, and production engineers working with plastic bottle inspection. Neck Finish The uppermost section of a plastic bottle or container, including the threads, sealing surface, and opening. The neck finish is defined by standardized dimensions including T (thread outer diameter), E (inner diameter), I (inner neck…
A reference glossary for quality, operations, and process engineers working with coated flat sheets in metal packaging production. Coat weight (film weight) The mass of dried coating applied per unit area of substrate, typically expressed in grams per square metre (gsm) or milligrams per square inch(mg/in2). Coat weight is the primary quality parameter monitored on flat sheet coating…
The challenge with traditional coating measurement on flat sheet lines For decades, metal packaging manufacturers have relied on gravimetric testing and capacitance-based methods to verify that coating film weights on flat sheets meet specification. Both approaches have a fundamental limitation in common: they are offline, snapshot-based, have measurement variability, and are reactive. With gravimetric testing, operators weigh sheets before and…
Flat Sheet Coating Measurement for Metal Packaging Production Flat sheet coating measurement is the process of determining the thickness or film weight of a coating - such as a lacquer, varnish, or base coat - applied to metal sheets during the manufacturing of packaging products such as cans, closures, and aerosol components. In metal packaging production, coated…
