U.S. Solid Aluminum Foil Cap Liner Heat Sealing for PET Bottle Lid(100 pcs, 20mm)

Works like it’s supposed to.

These do not form a seal at all. I have a heat induction machine that works with other foil caps and this one never sealed at all.

Needed something to seal my medicine bottle from the clinic. These work perfectly.(My clinic never seals them good enough and I'm tired of them spilling out. So I got my own machine and seals.... no more issue)

This seal fits perfect in the amber jars that I'm using.....excited that it's a perfect seal as well

This doesn’t work on glass jar

Spent more time redoing the seals. Total junk. Do not buy

Just what I needed to get the job done

Mala calidad, muy ligeros y no se adhieren bien
