Hyosung’s PP for specialty film has exceptional heat resistance which leads to excellent performance during retort sterilization process. With outstanding film processability, this film is also visually superior and can be used as protective films for optical materials, such as LCDs, or industrial materials.
Specialty films based on PP block copolymer can be used for either retort packaging material or optical protection films. Retort is a process that uses steam or superheated water to cook food in its own package, extending shelf life and ensuring food safety. To this purpose, CPPs must be able to withstand rigorous high-temperature during the process and should not be damaged during shipping. Strict requirements such as preserving taste and providing elegant exterior should be met.
Optical protection film is widely used for display electronics to protect the surface of optical materials (prism sheets, LCDs). They should not change in dimensions even throughout the various processing conditions or influence the optical materials in anyway.
