ALPACK is a very special packaging material specifically designed for use in environments where a barrier against moisture is required.
By virtue of its special three layer structure which can provide both self-adherence and, air and moisture impermeability, ALPACK is vacuumable and can be used for ensuring full protection of materials in many industrial sector.
ALPACK products, which are optimised to have PET on top, aluminium in the middle and polyethylene at the bottom, can be used to produce small aluminium bags as well as very large aluminium packages.
As is known, all kinds of polyethylene packing material allow air permeability at a certain extent. ALPACK is the most effective solution in cases where it is desired that the materials transported in it do not suffer a slightest damage even at dense humidity and when no air flow is desired from outside to the inside of the package. The absence of aluminium permeability provides this specific area of use for ALPACK products.
