Glassine Paper vs. Greaseproof Paper: What's the Difference?

When sourcing packaging and food-contact papers, buyers often encounter two similar-sounding options: glassine paper and greaseproof paper. While both are widely used for oil- and moisture-resistant packaging, their manufacturing process, performance, and applications differ. Understanding these differences is crucial for making the right procurement decision, especially for industries that require strict compliance with food-grade or industrial packaging standards

 

 

1. What is Glassine Paper?

Glassine paper is a supercalendered, smooth, and semi-transparent paper produced from highly refined pulp.

Surface & Appearance: Smooth, glossy, and translucent.

Grammage Range: Typically 30–90 gsm.

Key Properties:

Oil and grease resistance (achieved through dense fiber structure, not chemical coatings).

Moisture resistance.

Excellent dimensional stability.

High temperature resistance (up to 200°C for short periods).

Certifications: Glassine paper used in food packaging usually complies with FDA, EU (EC 1935/2004), or GB 4806 standards.

Applications:

Food wrapping (butter, baked goods, chocolate).

Release liner base for adhesive tapes and labels.

Envelope windows, interleaving sheets for electronics and metals.

Medical packaging (sterilization pouches).

 

2. What is Greaseproof Paper?

Greaseproof paper is made from refined chemical pulp and undergoes mechanical treatment (such as beating and pressing) to reduce porosity, making it resistant to oils and fats.

Surface & Appearance: White, opaque, with a natural matte finish.

Grammage Range: Typically 28–70 gsm.

Key Properties:

Strong resistance to oil and grease.

Moderate moisture resistance.

Breathable, suitable for hot food packaging.

Can be coated or laminated for additional barrier properties.

Certifications: Food-grade greaseproof paper must meet FDA, BfR, or ISO 22000 standards.

Applications:

Fast food wrapping (burgers, fries, bakery products).

Confectionery and snack packaging.

Laminated packaging materials.

Disposable tableware liners.

 

3. Key Differences Between Glassine and Greaseproof Paper

Feature	Glassine Paper	Greaseproof Paper
Appearance	Translucent, glossy	Opaque, matte
Oil Resistance	High, naturally from dense fiber	High, through refining process
Moisture Resistance	Strong	Moderate
Heat Resistance	Up to 200°C (short time)	Lower, suitable for direct food contact
Typical GSM	30–90 gsm	28–70 gsm
Applications	Release liners, food wraps, medical pouches	Fast food packaging, bakery wraps, snack papers

 

4. Buyer Considerations 

When choosing between glassine and greaseproof paper, buyers often focus on:

Barrier Properties: For products with high oil content (chocolate, butter), glassine offers stronger resistance. For quick-serve food packaging, greaseproof paper is usually more cost-effective.

Certifications & Safety: Food packaging buyers demand compliance with FDA, EU, or ISO standards. Without certification, papers may not pass customs clearance or meet retailer requirements.

Printability: Both papers support flexo and offset printing, but glassine's smooth surface ensures sharper graphics, while greaseproof's matte texture gives a natural eco-friendly look.

Sustainability: Both are biodegradable and recyclable, but glassine is favored for premium packaging, while greaseproof suits high-volume disposable use.

Cost & Supply Chain: Greaseproof paper generally offers lower cost per ton, while glassine provides higher performance per unit area. Buyers should balance unit price with performance needs.
