For these types of laminating machines, the lamination material comes in “pouches” which are actually two sheets of plastic film bound on one edge. Items are placed in an appropriately sized pouch, trimmed, and then placed in a cardboard carrier. The carrier is a simple piece of heavy card stock, similar to a file folder, and it protects the lamination pouch from direct contact with the hot rollers. Once a machine is warmed up and your item is snugly protected in the carrier, you place the closed edge of the carrier in the mouth of the laminating machine, and the rollers pull it slowly through, heating the carrier and lamination pouch. The heat reacts with the pouch, activating an adhesive which then binds to the paper, and the carrier exits the back of the machine with the newly durable, aesthetically enhanced item, ready to be placed on a wall, in a wallet, or wherever the laminated product will find its new home.
2. Cold Pouch Laminating Machines
If the document was printed on an inkjet printer, came from a fax, or is a photo, it may be sensitive to heat and a hot laminating machine could cause the colors to run. Cold laminating machines use pressure to activate the special cold laminating pouches. Some don't even require electricity and operating them requires simply inserting the cold pouch and turning the crank. Safer and easier to use, cold laminating machines can be a great option, but hot machines still produce better quality and durability.
3. Roll Laminating Machines
Roll machines are used in commercial and industrial settings where a large poster size is desired and speed is necessary. Roll machines don't use pouches. The lamination film is on a roll that's attached to the lamination machine, and the lamination film is heated prior to contact with the paper. This increases speed and efficiency and allows users to complete bulk laminating projects in a reasonable amount of time.
