Cap Liners

At The Cary Company, cap liners are designed to add a critical layer of protection between a container and its closure. Placed inside a cap, a liner helps create a secure seal that minimizes leaks, reduces product loss, and supports product freshness during storage and transit.

Depending on the liner style, cap liners and seals can also provide tamper evidence, moisture resistance, or compatibility with specific container materials like HDPE, PET, glass, or PP. Many of our bottle cap liners act as reliable bottle cap seals, helping customers safeguard liquids, powders, creams, and chemicals with confidence.

We offer a broad selection of cap liners to meet a wide range of packaging needs. Our inventory includes:

- Foam Liners: Popular all-purpose seals for bottles, these liners provide a compressible, leak-resistant seal and are commonly used in plastic caps.

- Pressure Sensitive Liners: These self-adhering cap seal liners bond to the container lip and offer tamper indication without the need for induction sealing equipment.

- Heat Induction Liners: Designed to create a hermetic seal when used with an induction sealer, these liners are ideal when stronger cap liners and seals or tamper-evident protection is required.

- Lift‑n‑Peel® Liners: A type of induction liner that offers easy removal after the initial seal, combining tamper evidence with consumer convenience.

- Sealing Disc Liners: Used in specific applications where a simple barrier or insert-style liner is preferred.

Many of these bottle cap liners are offered for different container materials to ensure proper sealing performance.

Our cap liners are available in a wide range of sizes to match common closure dimensions. The Cary Company stocks liners starting as small as 15 mm and extending up to 125 mm, covering many standard cap styles used with bottles, jars, and containers.

This size variety allows customers to find compatible cap seal liners whether they are sealing small specialty bottles or large industrial containers. We also offer caps with built-in liners for added convenience.
