[Honeywell (formerly AlliedSignal)] A registered trademark for an laminated barrier film. Aclar is clear, heat-sealable film composed of layers of Polychlorotrifluoroethylene (PCTFE) and Polyester (PET) sandwiched between two layers of Polyethylene (PE). The multifilm laminate provides a barrier for oxygen and water vapor. The thermoform-able barrier film comes in opaque and clear options. Traditionally, Aclar is used in pharmaceutical, medical, electronics, and military packaging. Aclar has been used to prepare sealed bags for low-oxygen level pest eradication.
Synonyms and Related Terms
Arclar (sp); thermoform barrier film; barrier film
Anoxic (low-oxygen level) enclosures for pest eradication
Inert, non-flammable, solvent resistant.
Physical and Chemical Properties
For 0.9mil film:
- Oxygen transmission: 13.9 ml/m²d
- Water vapor transmission @77F (25C) / 60% RH: 0.028 gms/m²/day
- Melting Point: 211°C
For more information see Technical Data Sheet
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.
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.
