Barrier layer foil for corrosion protection

The Trockenmittel-Beutel are used in connection with barrier layer foils. So that the desiccators take up and lower the air humidity in a packing, but again, barrier layer foils or not fixed deliver barrier layers are used.

Comming to grips with harmful humidity.

In order to protect from humidity damage, the atmosphere inside the packaging must remain below 50% relative humidity in the long term in order to avoided corrosion.

The following points must be taken into consideration for calculation:

Climatic zones that are passed
Duration of the transport
Duration of the storage
Water vapor permeability of the foil
Surface of the packing in m² (all 6 sides)

The right folie for every situation

Entsprechend werden unterschiedliche Sperrschichtfolien eingesetzt.

Polyethylene Barrier Foil

For transportation and storage periods with a maximum term of 1 year.

When using standardized packaging with polyethylene barrier foil it is important to use a foil with a total thickness of 200 microns and a maximum water vapour permeability rate of 0.5 g/m² in 24 hours and 23°C/ 85% RH (please also refer to DIN 55122).

Aluminum barrier foil

TL 8135-0003

Aluminum sandwich foil is suitable for a feed and a storage time from one year to five years.

Long-term packing must be e.g. welded in an aluminum sandwich foil, Tropac® barrier layer sandwich foil.

Sealed Barrier Packaging - Tin Barrels

A water vapour-close packing, which prevents the penetration of air humidity with security.
Uniquely along-packed air must be dehumidified from there.

In this case the temperature in the luggage space is to be considered. For the drying process of 200 l air space within the packing one needs 1 Einh/TM, related to the empty bundle.

With all packing absolute seam tightness and uninjuredness are natural.

Barrier Foil to meet the demands of higher requirements

Tropac® III offers a 100% protection against water vapour, oils and grease. The material is flexible, scrub and rot resistant and heat-sealable on the matt side of the product. Our barrier foils are also available as tubes, flat bags or crate liners.

TROPAgel® - Drying Agents
in combination with barrier foils are the perfect all-weather packaging. The barrier foils hermetically seal the packaged goods from the ambient air. The drying agent adsorbs and scavenges the remaining moisture from the bag’s interior.
