ATMOSIScience proudly announces that the Fiber Humidity Pack, engineered and manufactured by Shanghai HengyuanMacromolecular Materials Co., Ltd., has achieved full certification under the rigorous U.S. Food and Drug Administration (FDA) regulation 21 CFR 176.170. This milestone strengthens ATMOSIScience’s position as a global leader in manufacturing safe, reliable, and environmentally sustainable humidity control materials for food, pharmaceutical, and consumer applications.
Comprehensive Overview of FDA Regulation 21 CFR 176.170
The FDA’s Code of Federal Regulations (CFR) Title 21, Part 176.170 specifically regulates the components of paper and paperboard that come into contact with food. The objective is to control extractable substances under typical contact conditions to ensure safety and prevent harmful migration into food products.
Paper-based materials can contain additives such as binders, coatings, sizing agents, and colorants necessary for their function. FDA 21 CFR 176.170 mandates that these components do not release harmful chemicals or exceed specific limits of extractable migrates during contact with aqueous (water-based), alcoholic, fatty, or acidic foods, which represent broad categories of potential consumer products.
Rigorous Testing & Validation of Fiber Humidity Pack
ATMOSIScience engaged Shenzhen Southern LCS Compliance Testing Co., Ltd., a renowned independent laboratory, to test the Fiber Humidity Pack extensively from October 13-20, 2025. The testing regime was designed to mirror worst-case prolonged exposure to food under elevated temperatures and varying solvent conditions to challenge the material’s chemical stability:

The consistent results show excellent chemical inertness with extractable substances well within regulatory limits, reassuring potential users on product safety.
Advanced Material Composition & Sustainability
The Fiber Humidity Pack is composed of premium cellulosic fibers sourced responsibly, combined with biodegradable binders that meet industry environmental standards. This product not only ensures compliance with FDA requirements but also aligns with FSSC 22000 food safety management standards, SGS RoHS environmental compliance, and industrial compostability under EN 13432 certification.
This triple validation ensures that while delivering high-performance moisture control, the product supports a circular economy with minimized environmental footprint—crucial for firms prioritizing sustainability.
Real-World Application Insights
