• SteelResin™ Binding: Thermal resin creates a secure, permanent bind without punching holes through the pages.
• Multiple Spine Sizes: Available for documents ranging from approximately 15 to 340 sheets, depending on paper weight.
• Fast Binding Process: Insert the pages, heat the spine, allow the document to cool, and finish.
• Unibind Compatible: Designed for compatible Unibind and Peleman thermal binding systems.
• Professional Presentation: A cleaner alternative to comb binding, coil binding, stapling, and standard report covers.
• Title Page Visibility: Creates a customized appearance without requiring custom printing directly on the cover.

Choose the spine size based on the number of sheets and the paper weight. Standard 20 lb. paper allows a higher sheet count, while thicker 32 lb. presentation paper such as vPaper reduces the number of sheets that will fit.

Capacities are general estimates. Include the thickness of tabs, inserts, dividers, laminated sheets, or specialty stock when selecting a cover size.

Using heavier paper, tabs, inserts, dividers, laminated sheets, or specialty stock? Choose the next larger spine when the document is close to the stated capacity.

Choose the Unibind machine that best matches your document volume and preferred production method.

For best results, insert the pages evenly, complete the heating cycle, and allow the finished document to cool before handling.

Crystal Flex Covers are a strong choice when you want the title page visible and the finished document to look cleaner, more permanent, and more professional than a standard report cover.

Crystal Flex Covers are designed for professional thermal binding systems that create finished documents without punching holes through the pages. The steel spine holds the pages in position while the SteelResin™ adhesive bonds the document edge.

The clear front makes each document feel customized because the printed title page becomes the visible cover. This is especially useful when each report, proposal, manual, menu, or presentation requires a different title, project name, or customer name.

These covers are a practical choice for offices, schools, print shops, training departments, restaurants, real estate teams, professional-service firms, and businesses that produce polished bound documents in-house.

Peleman Industries has specialized in professional document presentation since 1939. Unibind systems and covers are engineered for reliable thermal binding, polished presentation quality, and repeatable in-house production.
