MyBinding Matte Writable Laminating Pouches

It depends on the marker, not the pouch. The matte finish is designed to accept ink from pens, pencils, and markers that a glossy pouch would resist, but whether that writing erases afterward comes down to what you write with. Dry-erase and wet-erase markers wipe off a matte surface cleanly, making the pouch genuinely reusable for something like a weekly schedule or chore chart. A regular ballpoint pen or permanent marker will write just as easily but won't erase, so if reusability matters, be deliberate about which marker type you hand out alongside the laminated piece.

No, temperature is driven by thickness, not by finish. A 3 mil pouch runs at a different, lower temperature setting than a 5 mil pouch regardless of whether the finish is glossy or matte, since the adhesive activation temperature scales with how much material the heat needs to pass through. Match your laminator's setting to the mil thickness printed on the pouch box, and the matte finish will laminate cleanly at that same setting a glossy pouch of identical thickness would use.

Lean toward the higher end of the available thickness range for anything handled and marked up daily, since a thinner pouch will show wear and scuffing from repeated marker use and erasing faster than a heavier one will. A thin pouch used occasionally holds up fine, but daily rewriting is a genuinely different use case than laminating something once and displaying it. If your piece is a card size rather than a full sheet, it's worth confirming thickness availability specifically within credit card laminating pouches since thickness options can differ by size.

Slightly, yes, and it's worth knowing that tradeoff is going on. Glossy finishes tend to make printed colors look a bit more vivid, while a matte finish softens glare and shine at a small cost to that pop, which is usually the better practical choice for anything read under overhead lighting. If the piece also needs to hang or clip onto something rather than sit flat, it's worth checking laminating pouches with slots so you're not solving the finish question separately from the attachment question.
