[Honeywell] A registered trademark for a moisture barrier film made from [[polychlorotrifluoroethylene|polychlorotrifluoroethylene]] (PCTFE).  Aclar films (sold by Honeywell) contain only PCTFE, which is an extremely good moisture barrier that is also thermoformable and used in many many packing applications. Films composed of only PCTFE do not provide a good oxygen barrier. Traditionally, Aclar is used in pharmaceutical, medical, electronics, and military packaging.

To provide an additional oxygen barrier, Honeywell recommends that Aclar is laminated with another substrate, such as PVC, EVOH, PE, Nylon, etc.  Several companies provide laminated versions of Aclar.

Description

Water Vapor Transmission Rates

Oxygen Transmission Rates
Source: * John Burke, Vapor Barrier Films

[Honeywell] A registered trademark for a moisture barrier film made from Polychlorotrifluoroethylene (PCTFE). Aclar films contain only PCTFE as an excellent moisture barrier that is thermoformable and used in many many packing applications. As such, Aclar is used in pharmaceutical, medical, electronics, and military packaging.

To provide an additional oxygen barrier, Honeywell recommends that Aclar is laminated with another substrate, such as PVC, EVOH, PE, Nylon, etc. Several companies provide laminated versions of Aclar. the PCTFE is laminated with Polyester (PET), then sandwiched between two layers of Polyethylene (PE). The multifilm laminate film provide a thermoformable, clear, barrier for oxygen and water vapor.

Examples of PCTFE laminate films as both moisture and oxygen barriers:

Collection Risks

Inert, non-flammable, solvent resistant.[1]

Physical and Chemical Properties

  • Extremely low permeability to water vapor and other gases
  • Does not crack in extreme cold
  • Sterilizable by heat, gas and radiation (below 2 MR)
  • Non-flammable
  • Extremely inert and solvent resistant
  • Heat-sealable

For 0.9 mil film:

  • Oxygen transmission: 13.9 ml/m²d
  • Water vapor transmission @77F (25C) / 60% RH: 0.028 gms/m²/day

Working Properties

  • Aclar is harder to seal than polyethylene and must be at 485 degrees F for one second at 50 psi (Burke, 1992).
  • Typically used in combination with Marvelseal for making anoxic enclosures for treating objects with insect infestations/pests. [2]
  • Can be laminated to a multitude of substrates, including Polyvinyl chloride (PVC), Polyethylene terephthalate (PET), Polypropylene (PP), cyclic olefin copolymer (COC) and Ethylene vinyl alcohol (EVOH) to add an oxygen and light barrier or create a more sustainable packaging solution for your application.[3]

Exhibit Construction Reviews/Tips/Case Studies

An open-ended heat sealer works well to seal Aclar and allows for custom bag shapes to fit objects.[4]
