Binding Covers Office Products A4 cardboard 250gsm glossy 100 pcs red

Office Products A4 cardboard binding covers, 250 gsm glossy, red — pack of 100. These A4-size covers are produced from sturdy 250 gsm cardboard with a glossy surface finish and are intended for use as front or back covers for bound documents, reports and presentations. The rigid cardboard gives the finished document a professional appearance, helps protect printed pages from wear and moisture at the edges, and pairs with separate spine elements in common manual and electric binding systems.

Advantages

The glossy coating enhances color fidelity and offers surface protection against light stains and scuffs. Supplied in a pack of 100, these covers are suitable for frequent use and bulk document preparation. The A4 format matches standard office paper sizes for consistent alignment and trim.

How to use

Choose the cover to match the document size and color preference, align the printed pages and spine elements, then position the cover as the front or back sheet before activating your binding machine or manually assembling the spine. Ensure the glossy side faces outward for the best visual effect and that pages are square to the cover edges to prevent misalignment. For hand insertion, slide pages into the spine elements and press firmly to engage; for machine binding follow the equipment manufacturer’s instructions for inserting covers and engaging the spine.

Usage recommendations

Store the covers flat in a dry environment to avoid warping; avoid prolonged exposure to direct sunlight to prevent color fading. For documents requiring additional protection, consider pairing these covers with transparent acetate covers or heavier backboards. When trimming or corner-rounding, use appropriate cutting tools and test on a single cover first to ensure the finish remains consistent.
