SMFLEX AIRTIGHT SEAL

Seal made from closed-cell foam, produced with low-density polyethylene (PE), in both laminated (both sides) and non-laminated versions.

Stands out for its high level of resistance, elasticity and high resilience. Ideal for guaranteeing customers the airtight sealing of any kind of package, bottle or container. Does not allow any liquid or air to pass.

These are typically the closure seals used most in the food industry, for pharmaceutical products, cosmetics and, in general, for all kinds of chemicals.

At SM Tecnic, we have a wide range of densities and thicknesses and can adapt to any diameter required, both in disc form as well as rings.

Our proprietary technology enables us to manufacture foam seals with variable geometry that can be adapted to any bottle with special mouths.

SMFLEX EPE seal

This is our standard in non-laminated polyethylene (PE) foam seals.

It offers excellent elasticity and an ideal resilience for creating an airtight seal in any container.

SMFLEX PE seals

Esta referencia es nuestro estándar en espuma de polietileno (PE) con laminado.

This is our standard in laminated polyethylene (PE) foam.

In addition to the elastic properties and high resilience of SMFLEX EPE, this product has a high-density HDPE-laminated layer on both sides. This increases the level of resistance to possible breakage as well as the resistance to products that, due to their composition and properties, could degrade other types of less resistant materials.

Además, esta capa de laminado añadida proporciona un mejor acabado, de más calidad.
