Laminated means covered with a thin protective layer of plastic. When something is laminated, it's sealed between sheets of clear plastic that are heated and pressed together, making it waterproof and much more durable.

You've probably seen laminated items everywhere: your school ID card, restaurant menus, classroom posters, and those reference sheets teachers hand out that you're supposed to keep all year. Libraries laminate library cards so they won't get torn or dirty in backpacks. Coaches laminate play diagrams so they can use them in the rain. Some people even laminate important documents or favorite photos to protect them from spills and wear.

The process creates a sealed barrier that helps keep moisture out and prevents tearing. That's why you can't easily write on laminated paper with regular pencil or pen, but dry-erase markers work great because the smooth plastic surface wipes clean.

Wood can also be laminated by gluing thin layers together. Laminated wood beams are actually stronger than solid wood of the same size because the layers support each other. Kitchen countertops often use laminated materials, with a decorative surface bonded to a sturdy base underneath.

When you laminate something, you're protecting it so it can last a long time. As a verb, laminate means to cover or bond something in layers, especially with plastic for protection.
