Aluminium-composite film for export shipments, maritime transportation and long-term storage

Our Tropac® III aluminium-composite film meets all relevant national and international quality requirements: The technical delivery specifications of the German Armed Forces (“Technische Lieferbedingungen”  TL 8135-0003), the German industry standard for aluminium-composite films (DIN 55531-Typ 1), and US military standards (MIL-PRF-131 K – class 1).

The Tropac® III film is available in various forms, e.g. on a roll, as a half tube, as  bag, as a box insert or as hooding, and can be tailored to your specific needs.

Tropac® III aluminium-composite film is tear-proof with high burst strength, resistant to water vapour and grease, smooth and supple, scrub-resistant, non-rotting, and heat-sealable on its matte side.

Aluminium-composite film providing strong protection against moisture

The water-vapour-resistant TropacIII® aluminium-composite film is ideal for reliably protecting corrosion-prone goods for maritime and long-haul transportation or long-term storage in climate-compatible packaging.
It is important to have hermetically sealed packaging that does not allow any additional moisture to enter. With the appropriate amount of desiccant, the atmosphere inside the packaging can be permanently kept below 40% relative humidity. You can use our DIN 55474-compliant calculator directly online to calculate the amount of desiccant needed to adsorb moisture.

The following key parameters must be taken into account in order to reliably protect long-term packaging intended for transportation and storage periods of between 1 and 5 years using TL 8135-0003 –compliant aluminium-composite film:

  • Packaging dimensions
  • The mass of any hygroscopic (moist) elements inside the packaging
  • The humidity of the air sealed inside the packaging
  • Permitted/desired final moisture content
  • Transportation/Storage duration
  • Climate during transportation and at the recipient’s end
  • Amount of water vapour penetrating through the packaging
