Unique Bargains PS Foam Resistant Tamper Pressure Sensitive Seal 50 Pcs

The foam lid liners are coated with a torque-activated coating, and after tightening the lid, they can stick to glass, plastic, and metal jars, as well as round containers with metal or plastic lids and closures. Advantages: Keep freshness: The pressure-sensitive seal made of polystyrene foam material effectively avoids dust, moisture, and dirt from entering the jar, preventing leakage and odor inside the bottle. In addition, it can also protect your products from tampering. Instructions for use: 1. Keep the lid that needs to be sealed clean, making sure there is no water and oily residue; 2. Put the lettering side of the seal into the lid and apply a little pressure to stick it tight; 3. Finally, tighten the lid as much as possible; the seal is activated by the pressure applied to the lid and will adhere within 12-24 hours (no strong adhesive). Note: 1. Make sure the correct size you need before ordering. 2. Once the seal is removed, the seal will be affected when used again. 3. These pressure-sensitive liners are best used for powders or dry products, not for applications containing oils; avoid overfilling the container. 4. It is recommended to wait a sufficient time after installation before removing the cover. 5. These PS foams are not suitable for use at high temperatures.
