Introduction
A key card folder is a fold-over holder — a flat card that folds in half to enclose a key card, usually with a clear window on one side and a lanyard hole for hanging. It’s the “wallet” form of card holder, distinct from a rigid holder, a slim sleeve, or an envelope.
For hotels, gyms, and membership programs, folders are a practical, brandable card carrier. This guide covers the fold-over structure, CR80 sizing, window materials, and bulk ordering.
What a Key Card Folder Is
The folder is defined by its fold-over, wallet-style structure.
| Trait | Key card folder |
|---|---|
| Structure | Folds in half |
| Card | Fits CR80 key card |
| Window | Clear, shows card |
| Lanyard hole | For hanging |
Compared to other card forms:
| Form | Structure |
|---|---|
| Folder | Fold-over wallet |
| Holder (rigid) | Hard shell |
| Sleeve | Slim open wrap |
| Envelope | Sealed mailer |
CR80 Sizing
Key card folders are sized to the CR80 card standard.
| Measurement | CR80 detail |
|---|---|
| Card width | 85.6 mm |
| Card height | 54 mm |
| Folder (folded) | Slightly larger |
| Folder (open) | Double width |
The folder folds around the card, so it’s sized for a snug, secure fit:
| Item | Size |
|---|---|
| Key card (CR80) | 85.6 × 54 mm |
| Folder (folded) | ~90 × 60 mm |
The Fold-Over Structure
The fold-over design is what makes a folder a folder.
| Element | Function |
|---|---|
| Front panel | Brand, logo |
| Back panel | Info, terms |
| Fold line | Card tucks in |
| Window | Shows card face |
The structure protects the card while keeping it visible:
| Benefit | Why it matters |
|---|---|
| Protection | Card enclosed |
| Visibility | Window shows card |
| Branding | Both panels printable |
| Hanging | Lanyard hole |
Clear Window Materials
The window shows the card and comes in a few materials.
| Material | Trait | Use |
|---|---|---|
| PVC film | Clear, durable | Standard |
| PP film | Clear, eco-friendlier | Eco option |
| No window | Solid front | Full print |
The window material is a durability and eco decision:
| Choice | Consideration |
|---|---|
| PVC | Durable, standard |
| PP | Recyclable option |
| No window | Max print area |
Printing and Finish
Folders are a branding surface, with finish options.
| Finish | Effect | Use |
|---|---|---|
| Four-color | Full brand | Standard |
| Foil stamping | Metallic mark | Premium |
| Emboss | Tactile | Luxury |
| Spot UV | Glossy highlight | Modern |
Match the finish to the property’s positioning:
| Property | Finish |
|---|---|
| Luxury hotel | Foil or emboss |
| Boutique | Spot UV |
| Standard | Four-color |
| Gym/membership | Four-color |
Use Cases
Key card folders serve card-carrying scenarios.
| Use case | Folder role |
|---|---|
| Hotel check-in | Card + welcome |
| Gym membership | Member card |
| Loyalty program | Member card + info |
| Event access | Credential carrier |
Two uses deserve note — hotels use folders to brand the check-in card, and gyms use them for member cards with rules and info inside.
Bulk Ordering
Folders are a volume purchase for properties and programs.
| Factor | Effect on cost |
|---|---|
| Volume | Lower unit at scale |
| Material | PVC/PP vs paper |
| Finish | Foil/emboss adds |
| Customization | Design setup |
Bulk ordering economics favor standard sizes and designs:
| Action | Why |
|---|---|
| Standard CR80 | Reuse die/design |
| Order in bulk | Lower unit |
| Lock design | Avoid re-setup |
Conclusion
Key card folders are the fold-over, wallet-style card carriers — CR80-sized, with a clear window, lanyard hole, and brandable panels. Choose PVC or PP for the window, match the finish to the property’s positioning, and order in bulk for the best unit cost. For the other card forms, see our hotel key card holders page.
