ATMOSIScience announces that the Fiber Humidity Liner, a state-of-the-art moisture barrier solution engineered by Shanghai HengyuanMacromolecular Materials Co., Ltd., has earned dual regulatory certifications from the U.S. FDA: 21 CFR 176.170 for food contact materials safety, and CPG 7117.05 for heavy metals safety compliance. This coveted dual approval exemplifies ATMOSIScience’s expert material engineering and product safety leadership.
Unpacking Dual FDA Regulatory Compliance
21 CFR 176.170
This code ensures paper-based packaging materials used in aqueous, fatty, and alcoholic food contact applications limit harmful substance migration, verified by chemical extraction analysis.
CPG 7117.05
The Compliance Policy Guide focuses on ensuring food-contact materials like paper and aluminum coatings are free of dangerous impurities such as lead (Pb). It guides acceptable limits to ensure no toxic exposure.
Achieving compliance to both standards requires precise chemical composition management and advanced testing protocols encompassing extractable substances and trace heavy metals: a recognition of outstanding product safety.
