VCI Papers, Foils & Laminates
Aluminium Barrier Laminate
The sealed-barrier workhorse: a three-ply laminate with an aluminium core, used where the pack has to hold out moisture and vapour for the whole storage period.
Key benefits
- Very low moisture and vapour transmission
- Heat-sealable into bags of any size
Technical specification
- Composition
- PET + AL + LLDPE
Full datasheet and SDS available on request.
How it works
The aluminium foil layer is what does the work: metal foil is effectively impermeable to water vapour, so transmission through the wall of the package drops by orders of magnitude compared with polyethylene. It is specified where moisture must be kept out rather than merely slowed.
