Should I refrigerate decade + old pack film that has never been refrigerated?

For late 90’s and early 2000’s pack film that had never been refrigerated, should I just keep it out, as it has been this whole time? Or should I throw it in the fridge? Is there even a point to doing that this late? Also is there a risk of ruining it by keeping it cold after it’s been room temperature for over 20 years?

Thank you for any advice!
