The liners are made of closed-cell polyethylene foam, coated with a barrier film on both sides.
EPE foam is produced through the extrusion process.
EPE/SARANEX foam liners have better barrier properties than standard ones.
SARANEX film contains PVDC in its composition.
Application:
For sealing closures used when capping bottles or jars with carbonated and non-carbonated beverages, non-alcoholic drinks (including mineral waters and juices), oils, facial creams, as well as alcoholic beverages with an alcohol content of up to 95%, including wine.
Available diameters:
From 14,55 mm up to 40,60 mm with tolerance ± 0,15 mm
From 42,00 mm up to 57,37 mm with tolerance ± 0,25 mm
Other diameters are available on request.
Technical parameters:
- Density: 250 – 500 kg/m³
- Thickness: 1,5 – 3,0 mm
- Flatness: max 10%
- SARANEX film thickness: 50 μm
- The thickness of the EPE core depends on the customer’s needs
- Density and thickness with a tolerance of ±10%
- Hardness at a density of 300 kg/m³: 75°Sh
- Maximum pressure for SARANEX gaskets: 2.5 – 3.0 bar.
Permeability of the SARANEX/EPE/SARANEX layer:
- Oxygen permeability: < 2 [cm³/m²·24h] (values 1.539 – 1.814)
- Water vapor permeability: 0.558 ± 0.010 [g/m²·24h·0.1MPa]
The SARANEX layer acts as a barrier to gases (oxygen, carbon dioxide), aromas, odors, fuel vapors, chemical products, MOSH/MOAH, and organic solvents.
