What are Greaseproof Paper and Wax Paper?

Greaseproof paper achieves its oil resistance through the paper itself. During manufacturing, the cellulose fibers are highly refined and densely calendered, which closes off the tiny gaps between fibers that oil would otherwise travel through. Some grades add a food-safe chemical treatment for extra resistance. The result is a paper that resists grease and oil from within its own structure, without relying on an external layer.

Wax paper, by contrast, gets its resistance from a coating applied after the base paper is made. A thin layer of paraffin or soy wax is applied to one or both sides of standard paper, and this wax layer is what blocks moisture and oil from passing through. The base paper underneath has little inherent resistance on its own.

This difference in approach, fiber-level treatment versus surface coating, is the reason the two materials behave so differently under real packaging and food-service conditions.

Key Differences in Performance

Because a coating and a fiber-level treatment respond differently to heat, moisture, and repeated handling, the two materials diverge sharply once they leave the comparison chart and enter actual production or kitchen use.

The heat resistance gap matters most for commercial use. Wax paper is not designed to touch heat sources or hot food directly, since the wax layer softens and can transfer onto food or equipment. Greaseproof paper has no wax to melt, so it holds its resistance whether the food is hot, cold, or fried, which is a large part of why it is the standard choice for professional food packaging rather than home use alone.

Common Applications

How to Choose the Right Option for Your Business

For most commercial and food-manufacturing applications, greaseproof paper is the stronger choice. It holds up under oven heat and hot, oily food, prints cleanly for branded packaging, and generally fits standard recycling and composting streams, which matters increasingly for businesses with sustainability commitments. Wax paper's lower cost and simplicity can work for light, non-heat, low-volume uses, but its limitations around heat, printing, and recyclability make it a poor fit once packaging needs to scale or meet food-service standards.

When evaluating which material fits your production line, start with how the paper will actually be used: Will it contact hot or fried food? Does it need to carry printed branding? Does your packaging need to meet food-contact or recyclability requirements? For most food-service, bakery, and quick-service packaging needs, these questions point clearly toward greaseproof paper as the more reliable, production-ready material.
