Add a plastic layer to your important documents with an A4 laminator. This way, you can give your papers a neat appearance and protect them from dirt and stains. An A4 laminator allows you to laminate paper with a maximum size of A4. You can also laminate smaller photos or maps. Laminating sheets come in different thicknesses. A thicker sheet provides better protection, while a thin sheet is more flexible. Make sure to properly check if the thickness of your laminator fits in your laminator.
