Release Coatings: How to Specify for Low Friction and Non-Stick
Release coatings help reduce sticking, lower friction, and improve cleanability in converting and web processes. This guide explains how to specify release coatings based on failure mode, operating environment, surface finish, and mechanical requirements. Release coatings get talked about like they’re a single thing: “We need a non-stick roll.” But in converting and web processes, […]
Hygienic Roller Surfaces for Medical and Pharma Packaging
Hygienic roller surfaces are important in medical and pharma packaging because small surface changes can affect cleanability, contamination control, and process consistency. This guide explains what makes a roller surface hygienic, where these surfaces matter most, and what to include when requesting a recommendation. Medical and pharma packaging lines are unforgiving. Small surface issues that […]
Bath Rollers and Squeeze Rollers in Sizing Lines
Bath rollers and squeeze rollers play a major role in pickup control, wetting, and uniformity in sizing lines. When roll surfaces change from chemical attack, abrasion, or build-up, the result is often cross-web variation, streaks, or unstable pickup. This guide explains what these rolls do, what usually goes wrong, and how to think about surface […]
Heat Transfer Rolls and Why Uniform Temperature Matters
Heat transfer rolls help control web temperature during converting and other continuous manufacturing processes. When temperature is not uniform across the roll face, it can lead to wrinkles, curl, adhesion issues, and product variation. This guide explains what heat transfer rolls do, why temperature uniformity matters, and what to include when requesting a quote. What […]
Corona Treatment and Dyne Level 101
Corona treatment and dyne level are closely linked in web converting, printing, coating, and laminating. If surface energy is too low, inks and adhesives will not wet out or bond consistently. This guide explains what corona treatment is, what dyne level means, and how to evaluate treater roll performance. What Is Corona Treatment? Corona treatment […]
A Study of Energy Savings In Corona Treatment of Packaging Films
During 2005, the New York State Energy Research and Development Authority (NYSEDRA) funded a multi-client study of the electrical energy utilization of the corona treatment process. The purpose of the study was to detail the energy saving (up to 40% reported) previously found with replacement glass-coated dielectric rolls used in corona treaters.
Factors Affecting Treater Roll Durability
The film manufacturing and converting industry creates an environment that is very tough on rollers and roller coverings. The continued drive for increased productivity, faster line speeds, and improved quality places added stress and wear on rollers and roller surfaces.
