Unique Bargains Pressure Sensitive Seal Adhesive Foam Lid Liner for Glass Plastic Bottle 300 Pcs 0.79"

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, so that dry or powdered products can always be kept fresh. In addition, it can also safely protect your products from tampering. Easy to use: These liner seals do not require an induction sealer or heat shrink tape. This foam seal is easy to peel off from the container when you need to open it. 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 tightly; 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 reused. 3. These pressure-sensitive liners are best used with powder or dry products and are not suitable 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.
