Which tape is better for resealing a FoodSaver heat bar?

Product B is the safer pick for a heat bar because it is rated to 500°F and has a fiberglass cloth backing. Product A is FoodSaver-branded and narrower, so it fits tight channels but has no published temperature rating.

Is the 1-inch tape too wide for my sealer?

It can be. Measure the sealing bar channel first; if it is about 1/2 inch, Product A's 1/2-inch width is the closer fit. Product B can be trimmed to width with scissors.

Which roll lasts longer?

Product B. It is 36 yards (108 feet) versus 30 feet for Product A, so roughly three and a half times the length.

Do both use adhesive?

Yes. Product A has an adhesive backing; Product B uses a high-temperature silicone adhesive. Product B's listing also notes liner and self-wound variants, so check which one you are buying.

Is one worth the extra?

Neither costs extra. Both are $5.99 at Amazon as of November 7, 2026, so choose on width, length and heat rating rather than price.

FoodSaver Replacement Sealing Tape Roll vs PTFE Teflon Tape for Vacuum Sealers

These are not the same part. Product A is a narrow 1/2-inch adhesive PTFE tape roll for sealing bars; Product B is a wider 1-inch PTFE-coated fiberglass cloth tape with a silicone adhesive, sold for insulating sealer bars and heat elements. Both are $5.99 at Amazon as of November 7, 2026, so price does not decide it. Buy A if you need a thin 1/2-inch strip to re-cover a worn sealing bar; buy B if you need a wider, tougher, higher-temperature barrier.
