FILM BLOWING

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.

DOUBLE BUBBLE FILM BLOWING

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.

MULTILAYER BLOWN FILM

Please check below a number of layer-designs from 2 layer up to 7 layers. The glue-layers are of great importance where two different polymers are not compatible.
