Cork Fabric Backing Materials: Microfiber vs PU Fabric — What's the Difference?
When it comes to cork fabric, the backing material plays a crucial role in determining the overall thickness, feel, and performance of the final product. At MB Cork, we work with two primary backing types: Microfiber Backing and PU Fabric Backing. Understanding the differences between them can help you choose the right material for your specific application.
Microfiber Backing
Composition
- Front: 100% Cork
- Back: 100% Microfiber Polyester
Key Characteristics
- Fray-Free Edges: Cuts cleanly without fraying, resulting in neat, professional edges — ideal for precision cutting and laser applications.
- Suede-Like Back: The microfiber backing has a soft, suede or alcantara-like texture on the reverse side.
- Thinner Profile: At approximately 0.7mm, it is thinner than PU fabric backing, making it lighter and more form-fitting.
- Flexible Yet Supportive: Soft and supple without being limp or floppy — it holds its shape well.
- Superior Durability: Highly resistant to repeated folding and flexing, offering a longer lifespan.
- Leather-Like Structure: The overall feel and structure closely resembles genuine leather, giving it a premium quality finish.
Best for: Accessories, wallets, card holders, and applications where a slim profile and premium hand-feel are priorities.
PU Fabric Backing
Composition
- Front: 100% Cork
- Back: 37%Polyester + 63% Cotton
Key Characteristics
- Stable Structure: The woven polyester-cotton blend provides a consistent, stable base throughout the material.
- Slightly Thicker: At approximately 0.9mm, it offers a bit more body than the microfiber option.
- Balanced Stiffness: Firm enough to hold structure without being rigid — not as soft as plain fabric, not as stiff as thick leather.
- Smooth Back Surface: The flat, smooth reverse side reduces friction during sewing, minimising thread skipping and needle drag.
- Production-Friendly: Excellent for high-volume manufacturing — the smooth backing improves sewing efficiency and reduces production errors.
- Good Durability: More durable than standard fabric, though slightly less fold-resistant than microfiber backing.
Best for: Bags, handbags, apparel, and products where sewing efficiency and structural stability are key.

Which Backing Should You Choose?
Both backing types share the same beautiful cork surface — the choice comes down to your product requirements and production process.
- Choose Microfiber Backing if you need a slimmer, more flexible material with a premium leather-like feel and clean-cut edges.
- Choose PU Fabric Backing if you need a slightly thicker, sewing-friendly material with a smooth back that performs well in high-volume production environments.
At MB Cork, both options are available in a wide range of cork textures and colours. If you're unsure which backing suits your project best, feel free to get in touch with our team — we're happy to help you find the perfect match.
