Lamination sheets and cartridges are what a laminator consumes: pouches in the standard document and badge sizes, roll film for high-volume and wide-format laminators, and the cartridge systems that make cold and cartridge-based laminators load in seconds. Signs, badges, instructions, flash cards, and anything else that must survive handling passes through one of these.
Match the supply to the machine first - pouch, roll, and cartridge laminators each take their own consumable, and roll and cartridge systems are usually specific to a machine family. Then choose thickness by the job: thinner film keeps documents flexible and cheap to run, thicker film turns them rigid and durable, and the laminator's rating caps what it can handle. For schools and offices that laminate constantly, buying the standard sizes by the case keeps the machine from sitting idle over a supply run. COLAMCO supplies lamination consumables alongside the laminators that use them for business, government, and education customers.
