Description
[Honeywell (formerlyAlliedSignal)] 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
Applications
Anoxic (low-oxygen level) enclosures for pest eradication
Personal Risks
Collection Risks
Inert, non-flammable, solvent resistance.[1]
