Description

[Cadillac Products Packaging Company] A registered trademark for a Barrier films made from Aluminum foil sandwiched between a biaxial nylon film and layers of heat sealable Polyethylene. Some types of CADPAK contain an additional layer of Heavy Duty green coex on one side. CADPAK films are strong, waterproof, vaporproof, greaseproof and flexible. Originally made for military applications, CADPAK films have found its way into museums and has been used to seal wooden packing crates, display cases, and storage shelves since 1980. It has also been used to create air-tight sealed enclosures for pest eradication.

Specific parameters for CADPAK products are:

CADPAK HD-200 Biax Nylon/PE/Cross-lam PE/PE/Foil/PE/Heavy Duty Green Coex 10.3 40 48 0.08 0.008 Link Heaviest duty, high puncture resistance

Applications

  • Lining shelves and shipping crates to minimize off-gassing of wood products
  • Create anoxic pouches for pest eradication or long-term storage
  • Sealed packages for exhibition and loan (esp for works on paper, paintings, lining inside of frames)
  • Protective covers for cabinets and cultural heritage objects

Collection Risks

CADPAK N is fairly inert.

Working Properties

  • CADPAK HD100 is about twice as thick as Marvelseal and relatively more robust
  • CADPAK HD200 white exterior turns clear with heat
  • Products with Nylon exteriors are paintable when corona treated (treatment lasts only a few days)
  • Adhesives will stick to Nylon and PET layers more readily than to PE

Forms and Sizes

  • Cost increases with thickness

Resources and Citations
