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/LDPE foam gaskets have better barrier properties than standard ones.
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.
Availabe 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 toelrance ± 0,25 mm
Other diameters are available on request.
Technical parameters:
- Density: 250 – 500 kg/m³
- Thickness: 1,5 – 3,0 mm
- Flatness: maks. 10%
- LDPE film thickness: 60 μm
- The thickness of the EPE core depends on the customer’s needs
- Density and thickness with a tolerance of ±10%
- Maximum pressure: 2.5 – 3.0 bar.
Permeability of the LDPE/EPE/LDPE layer:
- Oxygen permeability: 216.139 – 209.326 [cm³/m²·24h]
- Water vapor permeability: 1.34 ± 0.010 [g/m²·24h·0.1MPa]
The LDPE layer acts as a barrier to gases (oxygen, carbon dioxide), aromas, odors, chemicals, and MOSH/MOAH.
