If you operate a restaurant, fast food chain, bakery, or any food service business, you are almost certainly using grease-proof paper bags or liners. But there is a growing and increasingly urgent issue with conventional grease-proof packaging that every food business owner needs to understand: the chemicals used to make paper grease-proof.
Conventional grease-proof paper coatings use PFAS — per- and polyfluoroalkyl substances — also known as “forever chemicals.” These compounds have been linked to serious health concerns and are now being phased out or banned across North America and Europe. Fluorine-free grease-proof bags eliminate this risk entirely, without sacrificing grease resistance performance.
What Are PFAS and Why Are They a Problem?
PFAS (per- and polyfluoroalkyl substances) are a group of over 4,000 synthetic chemicals that have been used in food packaging coatings since the 1940s. They are called “forever chemicals” because they do not break down in the environment — or in the human body.
Multiple studies have linked PFAS exposure to serious health concerns including certain cancers, hormone disruption, immune system damage, and developmental issues in children. As a result, regulators across North America and Europe are moving rapidly to restrict PFAS in food contact materials.
In the United States, California, New York, Minnesota, and several other states have enacted or are implementing bans on PFAS in food packaging. The EU has proposed a sweeping ban on all non-essential PFAS uses under REACH regulations.
Fluorine-free grease-proof bags are now essential for fast food, bakery, and food service businesses
What Are Fluorine-Free Grease-Proof Bags?
Fluorine-free grease-proof bags use alternative barrier technologies to achieve oil and grease resistance without PFAS chemicals. The two main approaches are:
- Starch-based coatings: Plant-derived coatings that create a grease barrier — fully biodegradable and compostable
- Clay-based coatings: Mineral-based barriers that are highly effective against oils and greases
- Silicone coatings: Food-safe silicone barriers used in specific high-performance food packaging applications
Our Fluorine-Free Grease-Proof Paper Bags are available in pinch bottom and self-open formats, in 33–50GSM white or yellow paper, custom sizes from 60–500mm width.
Performance Comparison: PFAS vs Fluorine-Free
A common concern among food businesses considering the switch is whether fluorine-free bags perform as well as conventional PFAS-coated bags. Modern fluorine-free coatings have advanced significantly and now match conventional PFAS bags in most food service applications:
| Performance Factor | PFAS Coating | Fluorine-Free |
|---|---|---|
| Grease Resistance | Excellent | Excellent |
| Food Safety | Concerns — PFAS migration | Safe — no PFAS |
| Environmental Impact | Poor — persistent in environment | Good — biodegradable options |
| Regulatory Compliance | Increasingly non-compliant | Fully compliant |
| Cost | Slightly lower | Comparable — gap is closing |
Who Needs to Make the Switch Now?
If you sell products into California, New York, Minnesota, or any other state with PFAS-in-packaging restrictions, you need fluorine-free food packaging now. If you sell into European markets, the transition is equally urgent given the EU REACH proposals. And even if you are not yet in a regulated market, making the switch proactively demonstrates the kind of environmental leadership that resonates with today’s B2B buyers and their end consumers.
