A4 Laminating Pouches

A4 is the workhorse size — reports, certificates, classroom resources, signage for a door or noticeboard. The decision is micron, not size: 80 stays flexible for documents that get filed or handed around, 100 adds stiffness for menus and anything handled daily, and 125 upward gives rigidity for display. Gloss reads brighter, matt cuts glare under fluorescent lighting. Check the figure against your laminator maximum, or see all pouches.
