Nfinite produces semi‑finished ultra‑high barrier paper rolls that replace flexible plastic packaging. The paper is printable, heat‑ and cold‑sealable, and can run as a drop‑in replacement on existing horizontal and vertical form‑fill‑seal lines without lamination, while offering moisture, oxygen and grease resistance comparable to plastic. Its water‑based dispersion coating and spatial atomic layer deposition create an invisible, fully recyclable barrier, delivering a 40% lower carbon footprint than conventional plastic films.

Problem
Flexible plastic packaging provides essential moisture and oxygen barriers but is not recyclable in standard paper streams, leading to persistent environmental pollution and high carbon emissions. Manufacturers lack a drop-in material that matches plastic barrier performance while being fully curbside recyclable and compatible with existing high-speed packaging equipment.
Solution
Nfinite offers ultra‑high barrier paper rolls that replace flexible plastic films in packaging applications. The paper combines a high‑performance cellulose substrate with water‑based dispersion coatings and a nanometer‑scale barrier layer applied via Spatial Atomic Layer Deposition (SALD). This creates an invisible, multi‑layer ceramic oxide coating that delivers moisture transmission rates below 0.3 g/m²·day and oxygen transmission below 1 cc/m²·day, comparable to conventional plastics. The coating is ultra‑thin, non‑metallic, and dissolves during recycling, keeping the material 100 % curbside recyclable and compostable. Nfinite’s paper is printable, sealable (heat‑seal or cold‑seal), and engineered to run on standard horizontal and vertical form‑fill‑seal (FFS) lines without speed penalties, enabling manufacturers to adopt a sustainable alternative without retooling.
Target Audience
Primary customers are consumer‑goods manufacturers, food and beverage packagers, and CPG brands seeking recyclable barrier packaging that can be processed on existing high‑speed form‑fill‑seal lines.
Features
- Water‑based dispersion coating that primes and protects the paper while remaining invisible and recyclable
- Spatial Atomic Layer Deposition (SALD) creates hundreds of sub‑nanometer ceramic oxide layers, providing <0.3 g/m²·day WVTR and <1 cc/m²·day OTR
- 85‑95 % fiber content (50‑70 gsm) for high strength and flexibility on existing high‑speed FFS equipment
- Full compatibility with flexographic, gravure, and digital printing processes
- Heat‑seal and cold‑seal versions offering excellent sealability without additional lamination
- 100 % curbside recyclable in standard paper streams; coating dissolves during recycling, eliminating plastic waste
- Low‑temperature, high‑efficiency roll‑to‑roll coating (100‑300 m/min) reducing manufacturing carbon footprint
