Airtightness without adhesives or thermal processes.
We manufacture PE foam liners for caps that ensure tight sealing through pressure, without the need for heat or adhesives. We design solutions adapted to your cap and container to maintain a stable closure during storage and transport. At SM Tecnic, we develop each liner to perform reliably in production.
Simplify sealing and maintain control over every closure.
PE foam liners for containers are sealing elements that work through compression. They are placed inside the cap and, when closed, adapt to the container’s neck to create a barrier that prevents leaks and keeps the contents protected.
This system does not require heat or additional processes. The foamed material absorbs closure pressure and compensates for small irregularities in the container, allowing airtight performance across different formats and conditions.
We design them based on the type of cap, container material, and product behavior. We adjust density, thickness, and composition to ensure stable performance without deviations on the production line
We offer PE foam seals for caps adapted to each sealing need. We manufacture solutions that integrate into the cap, adapt to the container, and maintain their performance without causing production issues.
At SM Tecnic, we work exclusively with high-quality materials, control every stage of manufacturing, and adjust each configuration to ensure compatibility and stability. This process allows the liner to be adapted to different formats without compromising performance.
System that adapts to the cap and creates sealing through compression. It maintains closure without adhesion to the container and allows opening and closing without material degradation.
PE foam gaskets for caps provide a stable sealing system that is easy to integrate into different types of containers. We design each solution to respond to the closure’s behavior and maintain its function without complications in production.
This type of solution is especially useful in lines where a fast closure is required, without additional processes and with the ability to adapt to different formats. It enables airtightness without relying on heat or adhesives, simplifying the process and reducing potential deviations.
These are the benefits of this system:
Compression sealing
Adapts to the container and ensures airtight sealing without the need for heat or adhesives.
Opening and closing without deterioration
The material maintains its shape and allows the container to be reused without losing its sealing performance.
Easy integration into caps
It is placed inside the closure without modifying the production line.
Compatibility with Different Materials
Functions in plastic, glass, or metal containers depending on the configuration.
Stable in-line performance
Maintains its performance without causing issues in continuous processes.
Adaptation to each format
Adjust thickness and density to ensure the desired result in each case.
We work with expanded polyethylene liners for caps adapted to different industrial sectors. We adjust each solution to the technical requirements of the container, product, and process to ensure reliable sealing.

Protect your product, ensure container tightness, and avoid production issues. We manufacture PE foam liners for caps adapted to your closure and process, with controlled materials and configurations adjusted to each need.
At SM Tecnic, we develop solutions that work from the first seal and maintain their performance throughout the entire lifecycle.
If you need PE foam liners for caps, but have questions about how they work or how they adapt to your container, here we answer the most common ones. For a more specific analysis, contact our team and we will study your case.
It is a sealing element placed inside the cap. PE foam liners for caps create airtightness through pressure when closing the container.
It is used to prevent leaks, keep the contents protected, and ensure sealing without the need for heat or adhesion to the container.
Yes, PE foam liners for containers act as a sealing barrier and keep the product isolated during storage and transport.
