About this item

  • Size 50mm x 1mm / 1.97" x 0.04" (Dia x T); The foam lid liner is designed to fit bottles, ensuring that the outer diameter of the bottle mouth remains consistent with the diameter of the liner.
  • Advantage：The pressure-sensitive foam seals, made of polystyrene material, effectively prevent dust, moisture, and dirt from entering the jar. They also ensure leak-proof and odor-free bottles, keeping your dry or powdered products fresh at all times. These seals provide secure protection against tampering. No induction sealers or heat shrink bands are required for these liner seals. They can be easily peeled off from the container without the need for tools or a heat gun.

Once the seal is removed, the tightness will be affected when reused. 3.

These don't work. Neither way you try to put them, on 10 you will trash 8 because they don't seal and get broken.

these are true to size and you get plenty. the only thing I would advise is to review what kind of substance you are sealing. I tried to cap these on my lacqure paints and the paint melted through the foam. it disintegrated. they are not treated for solvents.

I wanted to try these on some empty jars I have that I’ve been using for essential oils. I wanted to be sure I got a good seal which is why I chose these. As long as the sizing is close these work. I’m so impressed with these I’m considering ordering a different size to match larger jars I have.These are relatively inexpensive given how many is in a pack. The foam liners are easy to use and the seal appears to be good. I doubt that I’ll ever need all 100, but it’s nice to have them on hand just in case. The quality of the foam lid liners is good. I would recommend these foam lid liners.

News to me that the sealed foam liners are actually pressure sealed. After trying these on some small 2 oz glass jars, sure enough! These liners are precisely cut and you simply put the on the opening and seal the jars...after a short period of time (15 minutes at least) you get a decent seal! It's recommended to keep the lid tight for 24 hours for the seal to be fully effective but it does work as advertised! Great product and does exactly what it's supposed to do, highly recommend!

I ordered this for the small jars I got in Amazon before. The jars were said to be 29.5mm/1.2", whereas this product claimed to be 30mm/1.18"......I selected this size because it was the closest to my jars' spec, however, it turns out to be at least 2mm larger than my jar cap's diameter.Very disappointed that these are now garbage to me. Recommend you to get a size smaller just on case to fit.The quality itself is ok. Some got bent in transport/at storehouse. It has a little bit of static to it plus slight stickiness to the white side that it sticks to the jar cap/jar rim quite easily. It would have worked well if the size is correct.Expensive though if you are using this for small business. If it's just one or two time home projects it's ok.

I’m not happy with these liners seals They don’t have any protection on the sticky side so the whole pack ended up sticking together. It was frustrating to separate them, and some were damaged in the process. Also they don't stick really well to the jar mouths. Definitely not what I expected, and I wouldn’t buy them again.
