3 types of laminating machines and how they work

Are you looking to buy a laminating machine? There are many types of these machines that you can opt for. Here are some of the most common:

Bag Laminator

This is a unit that heats the laminate and seals both sides. The unique feature of this unit is that the laminate is not attached to the machine. To laminate your document, you need to place the document you want to laminate inside the laminate bag and turn on the machine to heat it up.

Once you are ready, put the bag in the machine and the machine rollers will pull the bag through the heat. The two layers of the laminate consist of a polyester-based layer and an adhesive resin. When the two are touched and heated, the resin melts creating a hard surface and bonds with the polyester layer.

Large rolling mill

There are two types of this unit: large film and bag type. The type of bag is explained above. The large film laminator is designed to laminate large items or many items at the same time. To use the machine, you need to turn it on and place the items you want to laminate on the bottom sheet of clear laminate.

When you turn on the machine, the rollers pull the bottom layer while the top layer simultaneously unfolds. When the two layers of lamination touch, they seal thereby sealing the article on the inside.

Cold machine

This is a unique laminating machine that is designed for documents that are heat resistant. These include carbon copies and those with inkjet printing. This machine works by activating the laminate by pressure instead of heat. The document to be laminated is sent through the machine that rolls the two layers of documents together and presses them into place.

Tips for using laminating machines

For the machine to give you ideal results, it must give it time to warm up. The time you give depends on the model of your machine. You can tell if the machine is ready by looking at the indicator light. Once the machine is ready, the light flashes.

When laminating documents, be careful with the speed you use. As a general rule of thumb, laminate thick items like card stock at slower speeds. Use faster speeds on thin items, like notebook papers.


Here’s what you need to know about laminating machines. When buying them, be sure to buy them from a reputable store.
