How can be create a filter for a particular label ?

edit

Maybe the answer is to set a display filter like frame matches "\xAA\xBB\xCC" where AA, BBand CCare hexadecimal representations of the label's bytes?

I'm not sure what you mean by "label", but (almost all) elements that are displayed in the packet details pane protocol tree can be used in a filter, simply right click the element in the tree and use "Apply As Filter" | "Selected".

If you need multiple values of an element, then simply create additional filters, using an "or" (||).

When you have filtered to your satisfaction you can export the dissected packets using the menu item "File " | "Export Packet Dissections" | "As CSV...".

I have Arinc 429 protocol data captured for almost 10 minutes and I want to filter out a particular label in all the packets of data captured.

Unfortunately, standard releases of Wireshark don't appear to include any support for dissecting the ARINC 429 protocol, so there won't be any ARINC 429 fields that are filterable. If you have an unofficial ARINC 429 dissector, you will need to look at the list of named fields it provides, and see if any of them correspond to a "label" and, if so, find out what type that field has, so you can write a display filter expression that matches that label.
