Nfinite Achieves Major Roll-to-Roll Manufacturing Breakthrough for Eco-Friendly Paper Packaging

Nfinite's Breakthrough in Eco-Friendly Packaging

Nfinite, a cutting-edge materials firm specializing in next-gen high-barrier paper packaging, has made significant strides in manufacturing technology. On October 7, 2026, the company announced a remarkable achievement in the roll-to-roll production of its proprietary Atmospheric Pressure Spatial Atomic Layer Deposition (AP-SALD) system–a groundbreaking step towards revolutionizing eco-friendly packaging solutions.

Bridging the Gap Between Paper and Plastic

Paper has long been heralded as a promising alternative to conventional flexible plastic packaging. Yet, despite notable advancements in fiber-based materials, its ability to effectively substitute plastic has been limited due to inadequate barrier performance. Traditional paper often falls short in providing the protective qualities necessary to keep food and consumer goods safe for their intended shelf life.

The solution lies in atomic layer deposition (ALD), a technology that has shown potential in this arena. By applying transparent ultra-thin ceramic layers in nanometer thickness, products can achieve outstanding barriers against moisture and oxygen. Historically, however, ALD has been mostly confined to high-tech domains like semiconductors due to challenges in adapting it for continuous roll-to-roll manufacturing, particularly on flexible substrates.

Nfinite Breaks Through

Nfinite's significant milestone, confirmed at their pilot manufacturing facility in Waterloo, Ontario, displayed the successful coating of a continuous 24-inch-wide paper web, accomplishing speeds of over 100 meters per minute. Furthermore, the company is ambitious, aiming to expand the lengths coated to thousands of meters by year's end. This achievement validates that its proprietary AP-SALD technology can perform effectively under industrial conditions—a pivotal step toward scaling its commercial production.

In achieving remarkable coating uniformity and ensuring moisture barriers below 0.2 g/m²/day even in challenging tropical conditions, Nfinite has positioned itself to offer paper packaging that could match the shelf life of traditional metalized plastic films. This breakthrough is crucial for brands keen on transitioning from non-recyclable products to 100% curbside recyclable paper alternatives.
