"U" folder for A4 paper. Folder size: 22 x 30 cm. The folder is made of 1.2 micron PP foil, glossy, transparent. The package contains 50 folders with holes for inserting into a binder (The folders fit into all standard binders with two, four, six or eight holes).

It is important to know

Before choosing this type of folder, it is crucial to consider what kind of document management you will use it for most. Type U folders usually allow for quick insertion and review of individual sheets, but they have some limitations in terms of protection and portability compared to other types of folders. It is also worth paying attention to the thickness of the material, as differences in document protection are often less obvious from the format and type information itself.

• U-type folders are best suited for organizing individual documents or smaller sets, where speed of access and ease of insertion are key.
• Due to their open construction, they provide quick insertion and inspection, but less protection against falling out or moisture compared to folders that have a closure.
• The thicker material helps to protect against creasing, but it does not replace the locking mechanisms if you often carry large quantities of sheets.

In practice

🟢 Use for archiving and sorting individual documents

The U folder is very suitable for quickly organizing documents in drawers or cabinets where no additional closing method is required.

🟡 Transfer documents between meetings or locations

Suitable with limitations – the open side allows easy access, but increases the risk of paper loss when carrying a large number of documents.

🟢 Preparing presentation materials with transparency

Very suitable, as the transparent material and shine emphasize the neat appearance and enable quick visual recognition of the content of the material.

🔴 Long-term protection of larger document sets

Less suitable because the open construction does not protect the contents as well as closed folder types and is not optimized for large volumes of sheets.

Answers to frequently asked questions

Is this folder suitable for frequent document browsing?

Yes, U folders are designed to allow for quick insertion, removal, and viewing of individual sheets without additional obstacles.

How many documents does it make sense to store in one such folder?

Due to the open side, U folders are most practical for a smaller number of documents or sets where the thickness of the papers does not exceed the limits of the folder itself.

When would I prefer to choose a different type of folder?

If you expect frequent transportation of a large number of sheets or prolonged storage, we recommend using a folder with a closure (e.g. with an elastic band or button), as this better protects the contents from falling out or damage.
