Foam lid liners are coated with a torque-activated coating, after tightening the lid, they can be adhesive to glass, plastic, metal jars, and round containers with metal or plastic lids and closures.

Advantage
1. The foam lid liners are made of polystyrene foam which has a great leak-proof effect and can avoid dust, moisture, and dirt into the jar, maintaining the freshness of products and avoiding odors.
2. Easy to install or peel. No induction sealers or heat shrink bands are needed.

Instruction
1. Clean the bottle top thoroughly with a clean cloth to ensure there are no liquid, solid or oily residues;
2. Place the the lettering side of the seal into the bottle cap, apply a little pressure to fit it tightly (the white side of the seal should face down, and the side with black letters should face up.)
3. Screw the lid tightly, and the pressure of applying the lid activates the seal and will adhere within 12-24 hours.

NOTE
1. Please check the outer diameter of the bottleneck or the inner diameter of the cap before purchasing.
2. Place away from direct sunlight and high temperatures.
3. Once the seal is removed, the tightness will be affected when reused.
4. The liner is best sealed with powder or dry products, not suitable for applications containing oil.
5. Avoid overfilling the container.
