Carbonless Paper.
We have been producing the proven Giroform carbonless papers in our Bielefeld factory since 1979. Standard types are produced there under ISO 9001, ISO 14001, ISO 45001 and ISO 50001 and supplied worldwide.
The Giroform brand stands for high-quality carbonless papers with black copy on wood-free base paper. Giroform fulfils many of our customers‘ requirements. Naturally FSC or PEFC certified – and therefore particularly environmentally conscious.
All Giroform carbonless papers offer a high level of application safety and ease-of-use: from the printing process through further processing to disposal, being entirely recyclable.
With Giroform, we offer a market-driven, contemporary range of elemental chlorine-free carbonless papers in top quality. Giroform carbonless paper is distinguished by good running characteristics, an excellent copy, outstanding line sharpness and great printability.
Copyability is guaranteed for up to five years. The copy itself is guaranteed to last for up to ten years.

The copy is created as a result of writing pressure which causes a colour reaction in the interaction between the two coatings on the reverse and front sides of the paper.
The coating layer is composed of microcapsules that contain dissolved, colourless colour formers. Pressure caused by writing bursts the microcapsules. To produce a form, at least two sheet types (CB and CF) are required. For form sets with more than two sheets another sheet grade (CFB) is required as a middle sheet.
At a glance
- CB (coated back) – this sheet is the top sheet and therefore original of the form set. As a result of writing pressure, the microcapsules in the coating on the reverse side of the sheet are destroyed and the colour formers contained in them are released. This sheet grade is therefore pressure sensitive and requires correct handling.
- CFB (coated front and back) – this sheet serves as the middle or intermediate sheet in the form set and is coated on the front side with an absorbent receiving coating. During writing the released colour formers are absorbed and create an immediate colour reaction on the front of the sheet. The reverse side is coated with the same coating as the CB sheet. This sheet grade is therefore pressure sensitive and requires correct handling.
- CF (coated front) – this is the bottom sheet of the form set. The front side is coated with the same receiving coating as the CFB sheet. This sheet grade is not pressure sensitive and can be handled as normal coated paper.
