* Laminating pouches: These are the clear plastic sleeves that you place your documents in before laminating. They are typically made from a polyester film, sometimes with a heat-activated adhesive layer. The thickness (measured in mils) will vary; thicker pouches are more durable.
* Laminator (sometimes): Some kits include a basic laminator machine. The laminator itself will likely contain various plastics and potentially some metal components for heating and rollers. Different laminators use different heating mechanisms.
The instructions included in the kit may also specify any additional materials or cleaning agents.
