Description
[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 thermoformable 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
Applications
Anoxic (low-oxygen level) enclosures for pest eradication
Personal Risks
Collection Risks
Inert, non-flammable, solvent resistant.[1]
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
Working Properties
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]
