A heat laminator is a device used to protect and enhance documents by encasing them in a thin layer of plastic. It works by applying heat and pressure to seal the plastic around the paper, making it more durable and resistant to wear, moisture, and fading. This process is commonly used for preserving important documents, photos, and artwork. Heat laminators come in various sizes and styles, suitable for both home and office use. They typically require laminating pouches, which are available in different thicknesses. Users can easily operate these machines, making them a popular choice for crafting, presentations, and professional printing tasks.
