Aclar
Description
[Pentapharm (Honeywell for non-laminated Aclar))] A registered trademark for a barrier film made from Polychlorotrifluoroethylene (PCTFE). Most Aclar films contain only PCTFE (made by Honeywell) which is an extremely good moisture barrier, that is also thermoformable and used in many many packing applications, such as for pill dispensers.
As an oxygen barrier, the PCTFE is laminated with Polyester (PET), then 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

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]
