Triangle Pocket

A triangle pocket, also known as a corner pocket, is an interior fitting used in folders, binders, sample folders and writing pads. It is designed to hold loose documents securely inside the product while keeping them easy to access and remove.

What Is a Triangle Pocket?

A triangle pocket is usually placed in one of the inner corners of a printed product or presentation folder. Its diagonal shape creates a simple but effective holding area for loose sheets, brochures, inserts or business cards. Because the contents are held in place by the corner pocket, they do not need to be punched or permanently fixed.

Advantages of Triangle Pockets

Triangle pockets are especially useful when documents need to be transported safely but should remain removable. They help keep materials organized, prevent them from slipping out and allow the user to take them out quickly when needed.

This makes them a practical choice for presentation folders, ring binders, sample folders, writing pads and other printed products that combine a professional appearance with functional document storage.

Materials, Colors and Sizes

Corner pockets can be produced in different colors or as a transparent version. Transparent triangle pockets are often chosen when the inserted document should remain visible, while colored versions can be matched to the design of the folder or brand identity.

Different pocket depths, sizes and formats make triangle pockets suitable for a wide range of contents. They can hold standard paper formats as well as inserts that differ from common DIN A sizes. This flexibility makes them a useful interior element for customized printed products and presentation materials.

Typical Uses

Triangle pockets are commonly used to hold loose document collections, brochures, product sheets, certificates, price lists, business cards or smaller inserts. They are particularly helpful when the contents change regularly or when documents should be presented neatly without being permanently attached.
