Waterloo, Ontario – October 07, 2026 -- Nfinite has demonstrated continuous roll-to-roll production of its proprietary Atmospheric Pressure Spatial Atomic Layer Deposition (AP-SALD) technology at speeds exceeding 100 meters per minute, a milestone the company says proves recyclable high-barrier paper packaging can now be manufactured at industrial scale.
Nfinite coats a 24-inch paper web over 100 meters at 100 m/min
At its pilot manufacturing facility in Waterloo, Ontario, Nfinite coated a continuous 24-inch-wide paper web for more than 100 meters while running its AP-SALD platform at 100 meters per minute. The company is now targeting continuous coating runs of thousands of meters by year-end, moving beyond the lab-scale limitations that have historically confined atomic layer deposition to semiconductor and electronics manufacturing.
Moisture barrier performance hits 0.2 g/m2/day, matching metalized plastic film
The demonstrated web achieved coating uniformity with moisture barriers below 0.2 g/m2/day under tropical conditions, a result Nfinite says delivers projected shelf life equivalent to metalized plastic films. Matching that benchmark is the threshold brand owners require before replacing non-recyclable metalized plastic film with curbside-recyclable paper for food and consumer goods packaging.
CEO says the industry questioned whether ALD could ever scale for continuous manufacturing
"This milestone demonstrates that our vision is becoming an industrial reality," said Miguel Galvez, Chief Executive Officer of Nfinite. "For years, the industry has recognized the potential of spatial atomic layer deposition for packaging, but questioned whether it could ever be scaled for continuous manufacturing. We have now demonstrated that it can."
Co-Founder and CTO Jhi Yong Loke said maintaining atomic-scale coating precision while paper moves through a production line at more than 100 meters per minute represented "an extraordinary engineering challenge," while COO Guillaume Stal said the result shows the technology can be "manufactured continuously using processes compatible with commercial production."
University of Waterloo spin-off eyes first commercial facility to supply global packaging markets
The milestone supports Nfinite's plan to scale production through its first commercial manufacturing facility and supply high-performance barrier paper to global food and consumer goods packaging markets, offering brands a path away from conventional multilayer plastics without sacrificing shelf life or manufacturing compatibility.
