Laminating pouches are clear plastic sheets used to protect and preserve documents, photos, and other printed materials. They come in various sizes and thicknesses, allowing users to choose the right pouch for their specific needs. When heated, these pouches seal around the item, creating a durable, waterproof, and tear-resistant layer. To use laminating pouches, you typically need a laminator, a machine that applies heat and pressure to seal the pouch. This process not only enhances the appearance of the item but also extends its lifespan, making it ideal for important documents, educational materials, and crafts.
