When you shred laminated documents you may damage your shredder. Not to mention, the laminating film is not recyclable. So it's not a good idea.
Not all shredders can destroy laminated documents. Shredding these could blunt the cutting blades or even damage the machine. Some shredders are designed only to shred regular-sized paper. In addition, laminating film is not recyclable, so laminated documents should not be shredded purely for recycling purposes.
