This depends on what you want the Teflon tape to do - and what kind of Teflon tape you mean.

If you’re talking about the very thin, white plumber’s type of Teflon tape to wrap pipes - I don’t know the answer. That stuff is cheap and serves it’s purpose quite well.

However, if you mean the many types of Teflon tape that are either skivved (a thick piece of Teflon with adhesive applied) or coated (often a fiberglass with adhesive on one side and various thicknesses of Teflon coated to the other), then there are some options.

But first, let’s talk about Teflon. The word Teflon is a registered trademark of the DuPont Chemical Company (now Chemours) for the chemical compound PTFE (polytetrafluoroethylene). The company charges more for the same chemical compound (much like you pay more for Kleenex over a non-brand tissue - it’s about the branding).

So to start, any PTFE tape is going to be a good substitute for a Teflon tape, because PTFE tape is a non-branded version of the same chemical compound.Teflon Tape Manufacturers

However, even non-Teflon PTFE tapes can be expensive. But PTFE has some unique properties that cause it to have very low co-efficient of friction (meaning, it’s slippery and very little sticks to it). So then you want to look for materials that also have low co-efficients of friction in tape form. And, an issue many people have is that Teflon / PTFE tends to have poor abrasion resistance, so they want something that lasts longer.

If that’s the case, then next lowest co-efficient of friction / better abrasion resistant tape I know of is UHMW (Ultra High Molecular Weight). These can be made in a variety of thicknesses and adhesive systems. They are still not cheap tapes, but they are often less than Teflon / PTFE.
