For instance, I bought some Dremel bits and inside the packaging were these small extremely thin pieces of metal film. Not sure what they were used for or what metal they were made out of.

It accepts solder and I was able to connect wires to it. Is there a specific name for this type of material and does anyone know where I can get more?

I ended up using it as a makeshift "connector pad" to add surface area to the end of a tiny wire I was using to connect to a battery.

    Copper tape? It's thin and you can solder to it, but I have no idea whether that's what came with your bits. I'll leave the shopping to you. – Elliot Alderson Jul 13 '18 at 01:38

    `extremely thin pieces of metal film` ... you did not describe it very well .... the metal strips were probably inside a plastic jacket with a barcode printed on it ...... that is the theft prevention tag ..... it sets off an alarm at the store entrance if it is not deactivated at a checkout .......... http://www.eassecuritytags.com/uploads/pic/DR-label-barcode-ZLDRS2.jpg – jsotola Jul 13 '18 at 01:38

Nickel strip solders easily and well. You most often see nickel strip as the interconnection metal between individual cells inside battery packs. These strips are readily available from many suppliers and even on eBay.

Look for something called "tabbing strips".

Tin plated brass is a common solution
