The differences between fluorine-free oil-proof paper and ordinary oil-proof paper are significant in terms of composition, performance, and environmental friendliness. Here is a detailed comparison from multiple dimensions:、

（ Normal OGR ）

1. Core Composition Differences
Ordinary oil-proof paper:
It usually uses fluorine-containing compounds (such as fluorocarbon resins, perfluorooctanoic acid (PFOA), etc.) as the main components of the oil-proof coating. These substances can form a dense waterproof and oil-proof film on the paper surface, achieving oil resistance by repelling oil molecules.
Fluorine-free oil-proof paper:
It contains no fluorine at all. Its oil-proof coating mostly uses plant-based oils (such as modified soybean oil, palm oil derivatives), water-based polymers (such as acrylate, polyvinyl alcohol), or nanoscale inorganic materials (such as silica). It achieves oil resistance through physical barrier or molecular structure design.
2. Differences in Environmental Protection and Safety
Ordinary oil-proof paper:
Fluorine-containing compounds (such as PFOA, PFOS) are persistent organic pollutants (POPs) that are difficult to degrade in the natural environment. They may accumulate through the food chain and pose potential risks to human health and the ecological environment (e.g., affecting the endocrine system). Many countries and regions have restricted or banned their use (such as the EU REACH regulation, US EPA standards).
Fluorine-free oil-proof paper:
It uses natural or environmentally friendly materials, is biodegradable, contains no harmful substances, and is more friendly to humans and the environment. It complies with global environmental trends (such as standards for degradable packaging materials and safety certifications for food contact materials).
3. Cost and Market Application
Cost:
Ordinary oil-proof paper has relatively low cost due to the mature fluorine-containing coating process; fluorine-free oil-proof paper is usually slightly more expensive due to the newer R&D and production processes of environmentally friendly materials (but the cost is gradually decreasing with technological popularization).
Market trends:
With the tightening of environmental policies and the improvement of consumers' health awareness, the market demand for fluorine-free oil-proof paper is growing rapidly, especially in the food packaging field (e.g., high-end catering, organic food brands). Ordinary oil-proof paper is gradually withdrawing from markets with strict environmental requirements and is only used in scenarios with extremely high oil resistance requirements and loose environmental restrictions.

Summary
The choice between fluorine-free oil-proof paper and ordinary oil-proof paper depends on balancing oil resistance needs, usage scenarios, and environmental compliance:
Ordinary oil-proof paper may be more practical for high-temperature, high-oil foods or industrial scenarios with low environmental requirements.
Fluorine-free oil-proof paper is a better choice if environmental protection, food safety, or compliance with international environmental standards is a priority, especially for low-oil food packaging.
