Description
[Honeywell (formerly AlliedSignal)] A registered trademark for a series of fluorinated-chlorinated barrier films. Aclar® films (22A, 33C and Cx) are clear, heat-sealable film composed of layers of Polychlorotrifluoroethylene (PCTFE) and Polyester (PET) sandwiched between two layers of Polyethylene (PE), while Aclar® UltRx is a homopolymer film of chlorotrifluoroethylene. The multifilm laminate provides a barrier for oxygen and water vapor. The thermoformable barrier film are biochemically inert and resistant to chemicals, heat and radiation. 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
- Sample preparation for microscopy and embedding
Personal Risks
EMS Microscopy SDS sheet
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
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]
