14. How do you store any unused sachets?
You need to plan your production flow in a way that your sachets would not stay exposed to open air exceeding the allowed time period. If, for whatever reason, you have to stop your process (e.g. the shift goes on break or there were unused sachets left over) you need to place the unused sachets, if they were not exposed to open air over designated time period, inside a high barrier bag or the master bag and vacuum pack them with 99% vacuum.
