1. A method comprising:
- externally delivering thermal energy onto a first major bonding surface of a first moving polyester substrate so that the first major bonding surface of the first moving substrate is a heated surface;
externally delivering thermal energy onto a first major bonding surface of a second moving polyester substrate so that the first major bonding surface of the second moving substrate is a heated surface;
bringing the heated first major bonding surface of the first polyester substrate into proximity to the heated first major bonding surface of the second polyester substrate;
and,self-bonding the first polyester substrate and the second polyester substrate to each other to form a polyester laminate.
