Sztapel adjustable document covers sized for documents up to 250×450 mm provide transparent front and back protection for printed sheets, certificates and manuals. Supplied in a pack of 50, each clear protective cover accommodates varying document thicknesses thanks to its adjustable spine. The product is intended for temporary protection before binding, presentation use, filing and short-term archiving where visible, dust- and splash-resistant protection is required.
Advantages
The clear protective covers are made to maintain document visibility while shielding pages from dirt and light moisture. The adjustable design allows a single cover to fit different numbers of sheets, reducing the need to buy several fixed-size spines. The smooth edges protect document corners from folding and the transparent material ensures content remains readable without removal. A pack of 50 provides a practical quantity for office routines, schools or small print runs.

How to use
Slide the document or stack of sheets into the transparent front and back sides, aligning edges to the cover dimensions. Adjust the spine to match the thickness of the content so the cover closes evenly and holds the pages securely. For multiple or thicker documents, ensure the spine is set to a larger position to avoid bending pages. Remove covers gently when documents need to be bound or trimmed.
Usage recommendations
Store covers flat and away from direct sunlight to prevent warping or discoloration. Clean with a soft, damp cloth; avoid abrasive cleaners or solvents that could cloud the transparency. Use these covers for short- to medium-term protection and switch to permanent binding solutions for long-term archiving.
