A hot laminator is a machine used to protect and enhance documents by encasing them in a layer of plastic. It works by applying heat and pressure to seal the plastic around the item, creating a durable, waterproof, and tear-resistant finish. This process is commonly used for preserving important papers, photos, and educational materials. Hot laminators come in various sizes and are suitable for both home and office use. They typically require laminating pouches, which are available in different thicknesses. The heat from the machine activates the adhesive in the pouches, ensuring a secure seal around the document being laminated.
