It is important to know

Before choosing a spiral binder, such as the Klipko Spirale PVC 45 mm model, it is crucial to consider the size of the spiral to match the thickness of your document set and whether the selected plastic is suitable for the required load and business use. Pay attention primarily to the practical consequences of the choice in relation to the conditions in your office and any needs for standardization and organization.

• The 45 mm spiral size is suitable for binding larger documents; estimate the thickness of the set with any covers in advance so that the binding is compact enough and not too loose.
• The plastic design allows for greater binding capacity and greater flexibility when handling thick documents compared to wire spirals.
• Universal black is useful for internal standardization of business documentation or for separating document types.
• For smooth use, check the compatibility of the spirals with your binding machine - in the case of larger orders, a uniform choice in terms of size and material is recommended.

In practice

🟢 Binding of large documents and archiving

A spiral with a diameter of 45 mm is very suitable for archiving or binding larger sets of sheets, as it allows for the insertion of larger documents without the risk of overloading.

🟡 Binding of presentation or official materials

Suitable only with limitations – plastic allows for greater capacity, but the final visual impression is less solid than with wire spirals; for formal presentations, appearance may be a limitation.

🟢 Organization and color separation of documents

The product is very suitable if you need a standardized black color for easier identification or organization of project documentation within a department.

🟡 Frequent addition or removal of leaves

The spiral allows for ongoing intervention in bound documents, but repeated opening and closing may cause signs of wear on the plastic over time.

A 45 mm spiral is suitable for binding very large sets, usually over 400 sheets, but it is advisable to estimate the total thickness of the complete document, including covers, beforehand.
