FAQ

Fresh answers to fresh questions.

What bags does it work on?

Chip bags, candy bags, cereal liners, coffee bags, frozen food bags, bread bags, and most plastic or foil-lined snack packaging. If it crinkles, we can probably seal it. It's not designed for paper bags or very thick plastic (like heavy-duty freezer zip bags — those already seal!).

How long does a seal last?

A proper seal is airtight — your snacks stay factory-fresh for weeks, not days. Re-open with the built-in cutter (Seal'd Press) and re-seal as many times as you like.

Is it safe?

Yes. The heating element is recessed and only activates while pressed, and it cools within seconds. As with any heat tool, keep it away from little hands and don't touch the seal strip immediately after use.

How do I charge it?

USB-C, cable included. A full charge takes about 1.5 hours and delivers 400+ seals on the Press — most homes charge it once a month, if that.

How long is shipping?

Orders process in 1–2 business days. US delivery typically takes 7–12 business days, and you'll get tracking the moment your order ships.
