Vacuum Metallizing & Coating
Why Is My Vacuum-Deposited Barrier Coating Hard To Improve? Paid Members Public
The most frequently asked question that I get is, “Why is my barrier coating hard to improve?” Like the coatings, the answer can vary from simple for very basic barrier coatings to much more complex for higher-barrier performance coatings.
High-performance AlOx thin films for next-generation sustainable flexible packaging: Part 2 Paid Members Public
AlOx has long been touted as a suitable transparent layer for packaging applications and indeed has found use in a range of retort applications based on high-performance PET substrates.
Vacuum Verbiage: In these cost-conscious times, how do we save energy in metallizing? Paid Members Public
Globalization can have advantages, but we have seen the disadvantages in recent times with the impact of COVID-19 on travel, trade and individual freedom. More recently, the invasion of Ukraine by Russia has caused a massive increase in fuel costs. The increasing cost of fuel already was happening due to
VACUUM VERBIAGE | Are today's fillers for various polymer films a necessary evil? Paid Members Public
I have a tendency to view fillers as problematic; hence, the title of this column. Polymer films made without fillers often are very smooth, which makes them very hard to wind well. As the film is wound, the air between is squeezed out, and so there is a very high
Role of vacuum coating in sustainable flexible packaging Paid Members Public
Thin films deposited by vacuum coating, with their unusual properties of being extremely thin and relatively impervious to the diffusion of gas, water vapor and aromas, lend themselves to being ideal components for future recyclable packaging. This article will describe the main trend in vacuum deposition, including the development of
Metallized-PE films: Challenges & opportunities to meeting market needs for recyclable, high-barrier flexible packaging Paid Members Public
Currently, the only path to have flexible packaging recycled in North America is via Store Drop-Off programs, which require these packages to be predominantly based on polyethylene (PE). For many barrier applications, these PE packages must use an EVOH layer, metallizing or topcoating. We will look at all three as
