Should bakery products use greaseproof paper bags or regular kraft paper bags? This is one of the most frequently asked packaging questions among wholesale buyers. Although both materials are widely used in bakery packaging, they perform very differently when exposed to butter, oil, moisture, and heat.
A bag that works perfectly for dry bread may fail completely when used for croissants, donuts, or warm pastries. A bag that looks like it just “ran a marathon in a deep fryer” because of oil leaks will destroy your premium pricing faster than a stale croissant.
This guide explains the practical difference between greaseproof paper bags and regular kraft bakery bags from a professional B2B packaging perspective.
What Is a Greaseproof Paper Bag?
Greaseproof paper bags are manufactured using specially treated paper fibers that resist oil migration. Unlike standard paper, greaseproof paper creates a barrier that prevents oils and butter from penetrating through the bag surface. For bakery applications, the common grammage range for greaseproof paper is approximately 35–80 gsm, depending on the product.
Main Characteristics of Greaseproof Bags
- excellent oil resistance
- clean exterior appearance
- smoother paper texture
- food-safe direct contact material
- suitable for hot bakery products
Best Applications
Greaseproof bags are commonly used for:
- croissants
- butter pastries
- donuts
- Danish pastries
- muffins
- fried bakery snacks
The main reason buyers choose greaseproof material is simple: It keeps the outer bag visually clean, even after several hours of product contact.
This matters especially for premium bakery retail presentation.
What Is a Regular Kraft Paper Bakery Bag?
Regular kraft bakery bags use untreated kraft paper made from natural wood pulp fibers. Because kraft paper is stronger in structure and lower in cost, it remains the most widely used bakery packaging material globally. Standard bakery kraft paper usually ranges from 40-100 gsm, depending on product size and carrying weight.
Main Characteristics of Kraft Bags
- natural paper appearance
- strong fiber strength
- lower unit cost
- easier large-volume customization
- suitable for dry bakery items
Best Applications
Regular kraft bags are ideal for:
- baguettes
- sandwich bread
- cookies
- dry pastries
- takeaway bread
For large bakery chains, kraft paper remains the most cost-efficient choice.
Greaseproof vs Kraft: Performance Comparison
| Feature | Greaseproof Paper Bag | Regular Kraft Bag |
| Oil Barrier | Excellent (99% Resistance) | Poor (Rapid Absorption) |
| Breathability | Moderate | High (Best for Crusts) |
| Unit Cost | 10%–18% Premium | Budget-Friendly |
| 2026 Compliance | PFAS-Free / Aqueous Coated | 100% Recyclable / Compostable |
| Print Quality | High-Definition / Smooth | Organic / Matte / Earthy |
The “Hidden” Cost of the Wrong Choice
Many B2B buyers choose Regular Kraft to save on the initial PO (Purchase Order). This is often a mistake.
-
The “Soggy Bag” Refund: If a customer’s bag fails and stains their clothes, the cost of a refund or a lost customer far outweighs the $0.01 saved on a greaseproof bag.
-
Brand Erosion: Premium branding on an oil-stained bag looks “cheap.” In 2026, social media “unboxing” happens at every street corner; your packaging must be camera-ready.
Many wholesale buyers believe that choosing kraft paper with a higher grammage will achieve oil resistance. In fact, this is incorrect. High-grammage kraft paper cannot prevent oil migration; it will only increase your costs without delivering the desired effect. Therefore, greaseproof paper is a must for greasy products.
Dry bakery items do not create significant oil migration. regular kraft paper performs very well. For wholesale bread packaging, kraft remains the dominant solution. But for oily products, greaseproof paper bags are a necessity.
How to Optimize Your Purchasing Strategy
One of the biggest purchasing concerns is the price difference. In most wholesale orders, greaseproof paper bags are approximately 8% to 18% more expensive than regular kraft paper bags.
Most successful bakery chains utilize a Dual-Material Strategy:
-
For Laminated/Fried Products: Stick to 40gsm Greaseproof V-bottom bags.
-
For Crusty/Dry Breads: Use 70gsm SOS Kraft bags with a window for visibility.
-
For Custom Branding: Use Flexo-printing on both, ensuring a unified brand look across different materials.
This hybrid strategy not only saves costs but also fully leverages the advantages of different paper bags. It has also started to become mainstream in 2026.
2026 Trends: Functional Sustainability
B2B procurement is shifting from “just green” to “Smart Green.”
-
PFAS-Free Mandate: In 2026, traditional fluorochemical coatings are banned. At RBD Packaging, we use plant-based and aqueous coatings to ensure 100% food safety compliance.
-
Custom size: Customize exclusive sizes based on your products to enhance customer perception, control costs, and reduce unnecessary waste.
- FSC-certified: In any case, sustainability is non-negotiable.
Questions Wholesale Buyers Often Ask
Are greaseproof paper bags recyclable?
Yes, most greaseproof bakery bags are recyclable when produced with food-safe water-based treatment.
Can kraft bags hold warm bakery products?

Which bag is cheaper for high-volume bakery chains?
Regular kraft bags remain cheaper for dry bakery lines.
Is greaseproof paper suitable for custom printing?
Yes. It supports high-quality printing and premium brand presentation.
