There are two techniques of making film. One is the cast film process. The other is the blown film process. The difference in qualities is that the blown film is more christalline than the cast film.

AXON manufacture machinery for both processes.

The Double Bubble Film Blowing Technique is used for the manufacturing of shrinkable film and film-tubes for food-packagning and other product-areas. One example on food-packaging is Sausage Casings of polyamide. The machine set up is illustrated below.
