Barrier ALU film is a multilayer laminated film that usually contains:
– Aluminum (ALU) layer – serves as a vapor barrier and light barrier,
– PET and PE layers – provide strength and tear resistance, allow welding.
– Sometimes supplemented with a VCI layer for corrosion protection.

Features:
– ✅ Excellent moisture, oxygen and UV barrier – ideal for long term protection of sensitive materials.
– ✅ Anti-corrosion protection – especially in combination with desiccants (e.g. silica gel).
– ✅ Mechanical strength – resistant to tears and punctures.
– ✅ Tightness – can be hermetically sealed by welding.
– ✅ Light weight – contributes to reducing transport costs.

Use
– Protection of metal parts, machinery, electronics, optics, military equipment, etc.
– Used in export packaging – especially where there is a risk of high humidity (e.g. sea transport).
– Used in combination with desiccants and moisture indicators.

Benefits
– Long-term protection without the need for lubricants or chemical coatings.
– Suitable for bagging and vacuum sealing.
– Protects contents not only against corrosion but also against mould, oxidation and contamination.
