When evaluating cork fabric, the visible cork surface is only one part of the decision. The backing also plays an important role because it influences thickness, flexibility, hand feel, stability and the way the material behaves during production.
This guide explains the main cork fabric backing options used for professional B2B applications, including footwear, leather goods, upholstery, interiors, bookbinding and orthopaedic components.
The goal is not to replace a technical test, but to help designers, manufacturers and material buyers understand which construction may be more suitable before requesting samples or technical information.

What the backing changes in cork fabric
A cork fabric is made by bonding a thin layer of natural cork veneer to a backing material. This backing gives structure to the cork surface and helps determine how the material feels and performs in use.
Depending on the backing, the same cork surface can become softer, thinner, more structured, more flexible or more suitable for specific production processes.
The backing can influence:
- final thickness;
- flexibility and bending behaviour;
- hand feel;
- dimensional stability;
- suitability for footwear, bags, upholstery or covers;
- compatibility with cutting, bonding, wrapping or sewing operations.
For this reason, choosing the correct cork fabric backing is a technical decision. It should be based on the final product, the production method and the type of performance required.
Visual overview of cork fabric backing options
The infographic below provides a visual summary of the main cork fabric backing options and their typical fields of use. It should be used as a first orientation tool before requesting samples or technical information.
Cork fabric backing comparison
The most suitable backing depends on the application. A material used for heel covering does not necessarily need the same construction as a material used for upholstery, bookbinding or flexible accessories.
| Backing | Main characteristic | Typical use |
|---|---|---|
| R10 coagulated backing | Structured, flexible and leather-like hand feel | Footwear, heel covering, wedges, selected leather goods |
| A – 100% polyester backing | Thin and flexible construction | Applications where reduced thickness is important |
| R05 textile backing | Softer hand feel | Flexible accessories and selected applications |
| R13 coated backing | Construction suitable for upholstery use | Upholstery, panels and interior surfaces |
| R12 cotton GOTS backing | Cotton-based textile backing | Projects requiring a natural textile base |
| TENCEL™ Lyocell backing | Soft textile backing made with TENCEL™ Lyocell fibres | Cork & TENCEL™ versions and selected sustainable material projects |
| Stretch backing | Elastic construction available on selected cork texture | Orthopaedic insoles and specific technical applications |
This comparison should be used as an initial guide. Final suitability always depends on the selected cork texture, finish, production process and intended application.

R10 coagulated backing
The R10 coagulated backing is one of the most versatile options for professional applications. It gives the cork fabric a structured but flexible hand feel, closer to the behaviour expected from materials used in footwear and leather goods.
Its final thickness is approximately 0.75 mm ±3%, depending on the cork surface and finishing. This construction is often considered when the material needs to be handled, wrapped, bonded or shaped in footwear components.
R10 is especially relevant for:
- heel covering;
- wedge and platform covering;
- selected footwear components;
- structured leather goods;
- applications requiring flexibility with a more technical hand feel.
For footwear projects, R10 is often one of the first options to evaluate when comparing cork fabric backing samples. For more application-specific information, see cork fabric for footwear.
A – 100% polyester backing
The A – 100% polyester backing is a thinner construction compared with R10. Its final thickness is approximately 0.60 mm, making it useful when the project requires reduced material thickness.
This backing can be considered for applications where flexibility and thinness are more important than a more structured hand feel.
It may be useful for:
- selected footwear components;
- flexible accessories;
- applications requiring a thinner cork fabric;
- projects where overall material thickness must be carefully controlled.
Because thinness can affect handling, cutting and bonding behaviour, sample testing is recommended before final production.
R05 textile backing
The R05 textile backing gives the cork fabric a softer hand feel. It is generally less structured than R10 and can be considered for applications where a more flexible and softer material is preferred.
This backing may be suitable for selected accessories, covers or applications where the material needs to remain easy to handle and comfortable to bend.
R05 is not necessarily the first option for every footwear application, but it can be useful when the project requires a softer textile-based construction.
R13 backing for upholstery and interiors
The R13 backing is designed for upholstery and interior applications. It gives the cork fabric a construction more suitable for decorative surfaces, panels, seating or interior elements where stability and surface behaviour are important.
This backing is especially relevant for:
- upholstery;
- wallcoverings;
- decorative panels;
- interior design applications;
- seating and furniture surfaces.
When the final application is related to interiors or upholstery, R13 should be evaluated before selecting a backing intended for footwear or small leather goods.
For more details about this application area, see cork fabric for upholstery.
R12 cotton GOTS backing
The R12 cotton GOTS backing is a cotton-based textile support used when the project requires a more natural textile base.
This backing can be considered for designers and companies looking for a cork fabric construction with a cotton support. It may be relevant for selected accessories, covers, interior details or projects where the backing material is part of the selection criteria.
As with all cork fabric constructions, the final choice should consider the required flexibility, thickness, production method and surface finish.
TENCEL™ Lyocell backing
The TENCEL™ Lyocell backing is used for the Cork & TENCEL™ version. In this construction, natural cork veneer is bonded to a textile backing made with TENCEL™ Lyocell fibres.
This option offers a softer textile feel and can be interesting for projects where material selection includes both cork and a more refined textile support.
The Cork & TENCEL™ construction can be evaluated for selected accessories, design applications and material research projects where the backing is part of the product concept.
For more details, see the dedicated Cork & TENCEL™ page.
Stretch backing for orthopaedic and technical uses
The stretch backing is a more elastic construction available on the selected agglomerated cork texture 104.
This backing is mainly relevant for technical applications where flexibility and adaptability are important, such as orthopaedic insoles or specific components that require a more elastic behaviour.
Because this construction is linked to a specific cork texture, it should be evaluated directly with samples and technical information before production.
For this type of application, see also cork fabric for orthotics.
Which backing suits each application?
Choosing the right cork fabric backing becomes easier when the decision starts from the final product.
Footwear
For footwear, the backing must be selected according to the component: heel covering, wedges, platforms, insoles, footbeds or uppers may require different behaviour.
R10 is often one of the most relevant options for heel covering and structured footwear components, while thinner or more flexible constructions may be evaluated depending on the final use.
See also: cork fabric for footwear.
Leather goods and accessories
For bags, small leather goods, belts and accessories, the choice depends on the desired hand feel, flexibility, thickness and production method.
A softer or thinner backing may be useful for flexible accessories, while a more structured construction can be preferable when the material needs more body.
See also: cork fabric for leather goods.
Upholstery and interior surfaces
For upholstery, panels and interior applications, R13 is generally the most relevant backing to evaluate. Interior projects require attention to surface behaviour, bonding method, support material and final use.
See also: cork fabric for upholstery.
Bookbinding, covers and menu holders
For bookbinding, notebooks, covers and menu holders, the correct backing depends on folding behaviour, rigidity, bonding and the type of support used by the customer.
In these cases, it is important to test the material with the final production method before confirming the most suitable construction.
See also: cork fabric for bookbinding.
Orthopaedic applications
For orthopaedic insoles and technical applications, stretch backing can be considered when elasticity and adaptability are required.
Because these are specific uses, material evaluation should always be based on samples, technical requirements and production tests.
See also: cork fabric for orthotics.
Backing and surface treatment are not the same
A common misunderstanding is to confuse the backing with the surface treatment.
The backing affects the structure of the cork fabric. It influences thickness, flexibility, hand feel and the way the material behaves during production.
The surface treatment affects the visible side of the material. It can influence appearance, touch and surface behaviour, depending on the selected finish.
In simple terms:
- backing = structure, thickness and flexibility;
- surface treatment = appearance and surface behaviour.
Both elements are important, but they solve different technical needs. For this reason, the correct cork fabric should be selected by considering both the backing and the final surface finish.
Surface finishes, colours and decorative versions
The choice of backing is only one part of cork fabric selection. The same project may also require a specific colour, texture, print, laser effect or decorative surface.
Villani Leonello offers different cork fabric versions, including natural cork textures, coloured cork fabric, printed cork fabric, laser-engraved surfaces, laser-cut cork fabric, die-cut perforated cork and cork laminated onto lace fabric.
These decorative options should be evaluated together with the correct backing, especially when the material is intended for footwear, leather goods, interiors or design applications.
Why sample testing is important
A cork fabric backing cannot be selected only from a written description. The final choice should always be confirmed through samples and production tests.
Samples help evaluate:
- thickness;
- flexibility;
- hand feel;
- surface appearance;
- bending behaviour;
- bonding performance;
- suitability for cutting, wrapping or sewing;
- compatibility with the final support.
This is especially important for B2B projects, where the same material may behave differently depending on the application and the customer’s production process.
