A laminator is a machine that protects and enhances documents by covering them with a thin layer of plastic. This process makes papers more durable, waterproof, and resistant to tearing. Laminators are commonly used in schools, offices, and homes to preserve important documents like certificates, photos, and artwork. Using a laminator is simple. You place the document inside a special plastic pouch and feed it into the machine. As it passes through, the laminator applies heat and pressure, sealing the plastic around the paper. This results in a glossy finish that not only looks professional but also keeps the document safe for years to come.
