Pre-salted casings placed on a tube for easier application onto the stuffing nozzle. Casings on tubes don’t need as much rinsing before use, saving a considerable amount of time.
These are casings in their most basic form. Just like tubed casings, they are pre-cleaned and salted. The difference is that they come minus holding tubes and need to be thoroughly rinsed of salt both inside and outside before use.
NB: All the casings are salted, regardless of whether they are tubed or not.
