The present invention discloses an organic polymer film and a manufacturing method thereof. The organic polymer film is mainly manufactured by the following steps. Firstly, the step (A) provides a xylene precursor and a substrate, and the step (B) places the substrate inside of a plasma equipment. After that, the step (C) evacuates the plasma equipment while introducing a carrier gas which carries vapor of the xylene precursor, and the step (D) turns on a pulse power supply system of the plasma equipment, generating a short pulse for plasma ignition. Finally, the step (E) forms the organic polymer film on the substrate.

An improved inside of can curing technology is provided. One implementation uses narrowband, semiconductor produced infrared energy which is focused into the inside of the can to affect a very high-speed curing result and will directly impact the coating covering the inside walls of the can to rapidly cure the coating. Detempering and annealing of the aluminum can body does not have time to occur, thus leaving a stronger can with the same amount of aluminum or a can of the same strength but with less aluminum. It is also possible to eliminate the natural gas fueled oven that is the current standard and replace it with a completely hydrocarbon-free curing alternative that has superior performance. This high powered radiant, narrowband energy will be digitally controlled to introduce only the needed heat and to not overheat the can.
