Letter-size 3 mil thermal pouches

These GBC HeatSeal LongLife pouches are sized for letter documents and use a 3 mil thermal film. The pack contains 100 clear sleeves sealed on the short edge. They suit offices, schools or home users who laminate occasional items such as signs, certificates or reference sheets.

Thermal laminator compatibility and pouch limits

Thermal lamination requires a heated roller machine; the pouches will not work with cold or pressure-sensitive systems. The 3 mil thickness is rated for standard construction, meaning it handles light handling and filing but is not designed for heavy daily wear or rigid display. UV additive extends colour life, yet the film remains flexible rather than stiff.

Capacity and headroom for everyday jobs

One pack supplies 100 letter-size laminations, enough for a small batch of menus, ID badges or teaching aids. The EZUse alignment guide and disappearing mil icons help centre each sheet on the first pass, reducing waste. When documents need thicker protection, frequent handling or outdoor exposure, a heavier mil pouch would be required.

Questions about this item

Is the 100-pack the only quantity available for these GBC 3745003 pouches?

The product is sold as a single 100-pack containing one hundred letter-size pouches.

What does the 3 mil thickness mean for everyday document handling?

A 3 mil pouch adds a thin, flexible layer of protection suitable for occasional filing and handling of letter-size pages.

How does the sealed short side affect loading the pouch into a laminator?

Because the pouch is sealed on the short edge, you insert the sealed end first so the open edges trail behind during lamination.
