Key Advantages of the YY09 Series

  • Leak-Proof Induction Seal — heat fusion bonds the foil to the bottle rim for a firm seal that holds up during transport and storage.
  • Tamper-Evident — an intact foil seal shows the bottle has not been opened.
  • Protects Product Quality — the foil layer helps block air, moisture and light; high-barrier composite film adds extra oxygen, moisture and odor protection.
  • Vented Options — a vent hole with a breathable window relieves gas pressure and helps stop bottles from swelling.
  • Easy-Open Options — pull tab, half-tab lift-and-peel and ring-pull designs open by hand with no tools.
  • Custom & Factory-Direct — custom diameter, structure and print, with stable bulk supply and free samples on request.

How to Choose the Right Liner

1One-Piece or Two-Piece?

Choose two-piece when you want the pulp board to separate after sealing and stay in the cap as a cushion, leaving only the foil on the bottle. Choose one-piece when the board should stay bonded to the foil and peel off with it as a single part.

2Vented or Non-Vented?

Choose a vented liner for contents that may release gas during storage and transport — the vent hole with a breathable window relieves pressure and helps stop bottles from swelling. Choose non-vented for stable contents.

3Induction or Pressure Sensitive?

Induction liners need an induction sealer and give a heat-fused, tamper-evident foil seal on the bottle rim. PE foam and pressure sensitive liners are for lines without induction sealing equipment.

Frequently Asked Questions

What is the difference between one-piece and two-piece induction liners?

A two-piece liner is pulp board plus a wax layer and aluminum foil with a heat-seal layer. After induction sealing the wax melts and is absorbed by the board, which separates and stays in the cap as a cushion while only the foil stays on the bottle mouth. A one-piece liner has the board bonded to the foil, so the board does not separate and the liner is peeled off as a single part, often with a pull tab.

Do I need an induction sealer to use these liners?

The pulp board, foil, high-barrier, easy-peel, lift-and-peel and ring-pull liners are sealed by induction heat, so an induction sealer is required. PE foam and pressure sensitive liners are for lines without induction sealing equipment.

What does a vented liner do?

A vented liner has a vent hole with a breathable window. It seals the bottle like a standard liner while letting gas escape, which relieves internal pressure and helps stop bottles from swelling. It is intended for contents that may release gas during storage and transport — please test with your own product to confirm the venting performance you need.

Can the liners be made to my bottle size, with a vent, tab or custom print?

Yes. Diameter is customized to match your bottle mouth. Vent size and position, pull tab or ring design and printed text or logo can be customized on selected types. Send us your bottle mouth size, container material and the liner type you are considering.

How do I get a reliable induction seal?

Match the heat-seal layer to your bottle material (for example PE, PP or PET), keep the bottle rim flat and clean, and set cap torque and induction sealer power and speed during trial runs. Check the seal on sample bottles before starting full production.

What is the MOQ, and can I get samples?

MOQs vary by liner type, diameter and customization. Share your target volume with our team and we will confirm MOQ, lead time and unit pricing. Free samples and a quotation are available on request.
