The toughest laminate I have ever used is General Formulation 238 "Moto Mark". It is crazy thick and quite tough. It comes in 75 foot rolls because of how thick it is. It is pricey, though. We have a client that doesn't care about price. They wanted to most durable decals known to man. They are very satisfied. They order 1000s every month. The smallest is a 7" circle. The largest is ~14x35". General Formulations is having trouble keeping up with how much we use. At one point maybe 6 months ago we bought every 54" roll in the US that any of our vendors could find.
