Key Advantages of the YY09 Series

  • Heat & Pressure Sealing Compatibility — works with standard induction sealing equipment as well as pressure-sensitive application.
  • Tamper-Evidence for Consumer Trust — a broken liner signals the container hasn't been opened before purchase.
  • Moisture & Oxygen Barrier Protection — foam and foil layers protect hygroscopic or oxygen-sensitive powders.
  • Compatible with PET / HDPE / Glass — one liner family services every bottle and jar resin in the YY catalog.
  • Custom Sizing to Any Neck Diameter — liners are cut to match 28mm through 135mm+ openings on request.
  • Optional Branded Printing — Universal and PET liners are available with custom printed graphics.

When to Choose the YY09 Series

1Tamper-Evidence Required by Regulation

Choose a heat-seal liner whenever the category expects visible proof of first opening.

2Moisture-Sensitive Powder Products

Select PE foam or foil-backed liners to protect hygroscopic ingredients during storage and transit.

3Multi-Material Container Lines

Universal liners simplify sourcing when a brand mixes PET, HDPE, and glass across its SKUs.

Frequently Asked Questions

What is the MOQ for YY09 seal liners?

MOQs vary by liner construction and neck size. Share your target volume with our team and we'll confirm exact MOQ, lead time, and unit pricing for wholesale or OEM/ODM orders.

Can YY09 liners be custom sized to our container?

Yes. Liners are produced to match any neck diameter across PET, HDPE, and glass containers, and can be supplied as pre-cut wads or roll-fed for automated lining lines.

What's the difference between induction and pressure-sensitive liners?

Induction liners bond to the container neck under heat and a magnetic field for full tamper-evidence and hermetic sealing, while pressure-sensitive liners adhere on contact without heat sealing equipment — the right choice depends on your filling line and tamper-evidence requirements.

Which liner construction is best for moisture-sensitive supplements?

Foil-backed induction liners with a foam or pulp backing provide the strongest moisture barrier for powders and capsules; our team can recommend the right construction from the nine available based on your product and shelf-life needs.
