Braskem has introduced Flexus 9212XP (extra performance) resin to meet the demand for high performance laminated films for use in high speed automatic packaging processes. Advantages claimed include high resistance to punctures and impacts, low sealing temperatures, excellent hot tack and more stable Kinetic Coefficient of Friction (CoF) values after rolling.
Braskem states that tests conducted with laminated films stored at temperatures of 60°C, which simulates critical conditions during transport and/or storage, demonstrated that after exposure to heat, films produced with Flexus 9212XP maintain a CoF value of around 0.14 during 72 hours of exposure.
Films produced using conventional resins registered a significant change in CoF values that exceeded 0.35 after 24 hours of exposure, the company continues. ‘This increase in CoF values is undesirable, since the film cannot be used for automated packaging processes.'
