Greaseproof paper is mainly made from cellulose pulp. Its oil resistance comes from controlled fiber selection, refining, sheet formation, pressing, and optional food-contact surface treatment.

Unlike ordinary paper, its internal structure is designed to reduce the open spaces through which grease can pass.

From Pulp to Grease-Resistant Paper

Cellulose Fiber Selection

Greaseproof paper starts with plant-based cellulose fibers. The pulp may use virgin fibers or selected fiber blends according to the required paper performance.

Fiber quality can affect:

• Sheet strength

• Flexibility

• Folding performance

• Surface consistency

• Grease resistance

• Printing quality

For food-contact applications, the base material and processing aids should also match the intended market requirements.

Fiber Refining

During production, pulp fibers are mechanically refined. This process makes the fibers more flexible and allows them to bond more closely during paper formation.

A denser fiber structure provides fewer channels for oil to move through the sheet.

This means some greaseproof papers can resist oil without relying on a thick plastic coating.

Sheet Formation and Drying

The prepared pulp is formed into a continuous paper web. Water is then removed through pressing and drying.

Controlled production helps create:

• Stable thickness

• Even fiber distribution

• Consistent density

• Smooth roll formation

• Reliable grease resistance

• Suitable converting performance

Uneven formation may create weak areas where grease passes through more quickly.

Optional Surface Treatments

Different applications may require different surface structures.

Grease-resistant products may include:

• Densely refined uncoated paper

• Silicone-treated parchment paper

• Wax-treated wrapping paper

• Laminated Food Paper

• Paper with an approved grease-resistant treatment

These materials should not be considered identical.

Silicone treatment is normally associated with baking and non-stick performance, while wax treatment is more commonly used for wrapping and separation.

Is Greaseproof Paper Always Oven-Safe?

No. A greaseproof sheet used for burger wrapping may not be suitable for baking.

Oven suitability depends on:

• Base paper quality

• Surface treatment

• Maximum temperature

• Heating duration

• Food oil content

• Direct contact conditions

• Product construction

The intended use should be clearly confirmed by the paper supplier.

Common Greaseproof Paper Applications

Greaseproof paper can be developed for:

• Fast-food wrapping

• Burger packaging

• Sandwich paper

• Bakery liners

• Deli counters

• Food baskets

• Takeaway bags

• Air fryer liners

• Oven baking paper

• Food separation sheets

Each application may require a different thickness, grease-resistance level, heat performance, and printing design.

Common Material Misunderstandings

Greaseproof paper is not necessarily:

• Made from recycled newspaper

• Coated with wax

• Treated with silicone

• Laminated with plastic

• Suitable for ovens

• Safe at every temperature

• Untreated because it is brown

• Unsafe because it is white

The final material structure depends on the manufacturing specification.

Our Food Paper Production and Supply

Our factory was founded in 2008 and combines material development, paper production, processing, warehousing, distribution, international trade, and after-sales service.

Our food paper products include:

• Greaseproof air fryer paper

• Custom Food Wrapping Paper

• Parchment baking sheets

• Wax paper

• straw wrapping paper

• Laminated food paper

Selected products can be customized according to:

• Width

• Length

• Thickness

• Sheet shape

• Roll size

• Printing design

• Packaging quantity

• OEM or ODM requirements

This allows the finished paper to match food-processing equipment, wrapping methods, and retail packaging.

Understanding the Final Material

Greaseproof paper begins with cellulose pulp, but its final performance depends on fiber refining, sheet density, pressing, drying, and optional surface treatment.

Buyers should confirm the material composition, food-contact application, heat limit, grease resistance, and supporting documentation before ordering.
