Montserrat font (SIL Open Font License 1.1)

Good afternoon!
Can we use the Montserrat font on the paper packaging of a pharmaceutical product (i.e. our client will use this packaging in a commercial activity, this medicine will be sold in pharmacies)?
Unfortunately, nowhere can I find a license and information that would confirm that we can use this font on the packaging.
Does the “SIL Open Font License” allow such use?

I’m assuming you are referring to Google Fonts: Montserrat which is license under the Open Font License (OFL)?

Yes, the SIL Open Font License permits such use. See the first three points of the OFL FAQ for more details.

The home for the OFL itself and the license text is available here.
