Barrier films for blister packaging using liquid crystal polymers

Abstract

The present disclosure provides a blister package utilizing a high-barrier film made from liquid crystal polymers (LCPs). Due to their highly ordered molecular structure, LCPs exhibit superior barrier properties against moisture and gases, making them ideal for pharmaceutical and food packaging applications. In some embodiments, the LCP film is laminated onto a polyester substrate, such as amorphous polyethylene terephthalate (APET), using an adhesive system to create a composite that is mechanically strong and thermoformable. The method of production can include forming the LCP film via extrusion or solution casting, orienting it by stretching in one or more directions, annealing to enhance barrier properties, and laminating it to the substrate. In some embodiments, a halogen-free, environmentally friendly packaging solution is provided that addresses the need for high-performance barrier films, offering improved protection for sensitive products.
