Nanwang Leads Fluorine-Free Revolution: Greaseproof Paper Meets China’s New Food Packaging Standards

National Policies Drive the Shift: Fluorine-Free Greaseproof Paper Emerges as Industry Standard

Recently, the National Food Safety Risk Assessment Center, entrusted by the National Health Commission, is leading the revision of the “National Food Safety Standard for the Use of Additives in Food Contact Materials and Products” (GB 9685-2016) and which has opened it up for public comments. This move sends a clear signal: the “fluorine-free” transformation of food packaging materials has entered its countdown!

Traditional greaseproof paper relies on fluorinated compounds (PFAS) for its oil-resistant function. However, PFAS, due to its “forever chemical” characteristics, easily accumulates in the human body and the environment, posing health and ecological risks. This standard revision marks China’s accelerated elimination of fluorinated additives, promoting the upgrade of food packaging towards safer and more environmentally friendly options.

Fluorine-Free Greaseproof Paper: A Dual Choice for Health and Environmental Protection

Currently, there are two main types of mainstream fluorine-free greaseproof paper on the market. These are environmentally friendly alternative developed to address the environmental pollution and health risks of traditional fluorinated oil repellents (such as PFAS/PFOA). Based on raw material sources, they are mainly divided into two categories: petroleum-based and bio-based.

1. Petroleum-Based Fluorine-Free greaseproof Paper
   Production Principle: A low-surface-energy coating or physical barrier layer is formed on the paper surface using petroleum derivatives, reducing the penetration of oil and water.
   ✅ Advantages
   •Delivers stable performance: Achieves KIT 6 oil resistance. Excellent high-temperature resistance, suitable for hot food packaging. Abundant petroleum raw material reserves, mature production processes, and controllable large-scale production costs.
   •Strong Process Adaptability: Can be directly integrated into existing paper bag production lines without major equipment modifications or auxiliary material replacements.
2. Bio-Based Fluorine-Free Greaseproof Paper
   Production Principle: Utilizes the self-assembly, modification, or compounding of biological macromolecules to construct nano-barrier structures.
   ✅ Advantages
   •Environmentally Friendly: Raw materials are renewable and compostable. No bioaccumulation toxicity, in compliance with European and American PFAS bans.
   •Multi-functional: Oil resistance can reach KIT 6, capable of resisting 85℃ hot oil for 30 minutes without penetration.
   •Food Safety: Bio-based components (such as cellulose, chitosan) are GRAS (Generally Recognized As Safe) substances with no migration risks. Nanwang’s fluorine-free greaseproof paper is an environmentally friendly product developed based on petroleum-based and biomass-based materials, eliminating the use of fluorides at the source and providing a superior solution for the Food Wrapping Paper industry.

Nanwang’s Fluorine-Free Greaseproof Paper: Four Core Advantages Redefining Food Packaging

1. Fluorine-Free and Healthy: A Safe Choice
   “Fluorine-free” means that the fluorine content meets the indicated value requirements and is not intentionally added. Fluorine-free greaseproof paper differs from existing greaseproof paper produced with fluorinated compounds (PFAS), reducing the chance of fluorine substances coming into contact with the human body, and does not contain substances harmful to humans, meeting market demand for prohibiting fluorinated compounds in food packaging, ensuring safety and health.
2. Environmentally Sustainable, Recyclable
   Utilizes biomass-based materials, 100% naturally degradable, and supports paper recycling, reducing resource waste. The non-laminated design avoids the environmental burden of traditional laminated paper, which is difficult to degrade, contributing to carbon neutrality goals.
3. 3. Efficient Oil Resistance, Excellent Performance
   Oil resistance reaches the industry-leading KIT 6 level, easily resisting hot oil above 85℃, suitable for various scenarios such as fried foods, fast food takeout, and baking packaging, balancing environmental protection with practicality.

• KIT test method, no penetration marks.
• 85℃ hot oil test, no penetration marks.
  4.Widely Applicable to Various Food Packaging Scenarios
• Western Fast Food Industry: Fluorine-free greaseproof paper is becoming a core choice for packaging upgrades in the Western fast food industry. Functionally, its efficient oil penetration resistance can withstand oil erosion from high-grease foods like hamburgers and fried chicken, while maintaining paper breathability to keep food crispy. It not only meets increasingly strict global environmental regulations but also eliminates the risk of chemical substance migration at the source, ensuring food safety and helping fast food brands achieve green transformation and enhance brand value.
• Baking Industry: Used for packaging bake goods such as cakes, bread, and biscuits, it not only prevents oil but also preserves the aroma and taste of the food.

Participating in Industry Standard Setting, Nanwang Leads the Green Revolution

In May 2024, the group standard “T/CSTM 01169—2024 Evaluation of Fluorine-Free Greaseproof Plant Fiber-Based Materials for Food Contact” officially released, led by the Environmental Paper Industry Professional Committee of the China Chemical Information Association, and will be implemented starting August 16th. Nanwang as one of the important drafting units of this standard, deeply participated in the formulation of technical indicators and testing validation, providing quantifiable green evaluation criteria for the industry.

This honor is not only an affirmation of Nanwang’s technical strength but also demonstrates our determination to drive sustainable industry development through innovation. In the future, we will continue to work with upstream and downstream partners to accelerate the widespread adoption of fluorine-free greaseproof technology, making health and environmental protection within reach!
