Generally speaking, air bubble film is constituted of tiny resin beads with different properties. To produce the air bubble film, the air bubble film machine is a necessity. Before using the air bubble film making machine, the mixture of resin should get melt to form a thin film. Then, the film is flattened to the needed thickness and fed through a roller.

There are countless small holes in these rollers. So, the air bubble film equipment is capable of infusing air onto the film to form the bubble. Once the air is infused into the film, the air air bubble film machine would use more rollers to seal the air with another layer of film. Then, after the second layer of film successfully traps the air, the air bubble film is good for cutting.
