KTRIOLaminating Sheets 5 Mil, Hold 8.5 x 11 inches Sheet, 200 Pack Clear Thermal Laminate Pouches for Laminator, 9 x 11.5 inches Lamination Sheets, Home Office School Supplies

3 mil sheets came with my laminator as part of the starter kit. 3 mil work okay but are thin and sometimes wrinkle while going thru the laminator, and sometimes have a slight curl when exiting the laminator. 5 mil laminate much nicer. The end result, no wrinkle, no curl and are thick just enough that they look and feel professional.Go with the 5mil, you won't be disappointed.

Nice thick sheets. Finished product is not flimsy, it is very sturdy. This is my second box. That should speak for itself. No need to use lamination pouches with these.

Just that really: a very keen value pack of useful sizes. They are a good thickness, cleanly cut, and they seal exactly as you would expect. There's not really anything more you can ask. Recommended.

Works great in my laminator.

I use five mil on all my laminating documents because they go onto walls in a restaurant. I laminate our plating guides, our recipe cards, etc.. these hold up very well, I’ve had things I’ve posted up for years still in the same spot (I do clean around those spots yes lol) overall great value great product and I will continue to purchase these as long as they are available.

they do their job impeccably and with very good transparency.

For those who are complaining that they are not clear, you have to take the protective film off of them first.

Heavy laminate, great size assortment.
