Need to find rolls of double sided sheet adhesive to hold down small parts on a CNC router table

My CNC router has a vacuum table to hold larger parts but some times I have to cut small letters and parts that the vacuum table will not hold down. Up until now, I’ve resorted to using contact adhesive to hold down the substrate to a scrap piece of material. The issue with this is that I have to clean the contact adhesive off the parts after they’re cut and it’s a pain in the neck. I’d like for find rolls of adhesive sheets that are at least 10″ wide. Any help would be appreciated.
