FlexFilms, the global film manufacturing arm of Uflex, has launched two new state-of-the-art BOPET Films: FLEXMETPROTECTTM F-HBP-M and FLEXPETTM F-HPF.
FLEXMETPROTECTTM F-HBP-M is a metalized biaxially oriented polyester (BOPET) film with a superior gas barrier that offers high moisture and oxygen barrier for virtually all applications, including aluminium foil replacement. High barrier comes from patented BOPET film technology, with high optical density specifically suitable for most flex pack product offerings. This film is 100 percent web inspected using advanced web metalized surface inspection system.
“With very high optical density, F-HBP-M film has superior tangible advantages,” notes Dr. Steven J. Sargeant, general manager, technology, at FlexFilms USA. “It is one side highly surface modified and other side metalized on corona treatment providing superior gloss, high tensile strength and advanced gas barrier properties. This film is suitable for extended shelf-life applications, including the replacement of Al foil in many flex pack configurations. Converters are able to generate less scrap and have less downstream customer rejections due to improved film machinability and handling properties when compared to legacy solutions.”
The film is EU and FDA, making it an ideal choice for products requiring foil replacement and extended shelf life with high barrier against oxygen and moisture. It’s especially useful in products that require aroma management, like packaging of coffee and medicines, snacks, dried meats and nuts.
FLEXPETTM F-HPF, is a first-of-its kind biaxially oriented nylon replacement (BON) film made with a newly developed patent pending technology that offers important features of thermoforming performance, high puncture resistance and flexural fatigue strength. This technology is suitable for many applications, thereby providing a replacement for biaxially oriented nylon (BON) in many applications.
“F-HPF is a transparent polyester film having the options of either both sides being untreated or one side being left untreated and other side being corona treated,” says Sargeant. “Due to the enhanced flexibility of the film, it offers pinhole resistance, along with enhanced puncture and crack robustness. These class-leading properties enable this film grade to withstand aggressive handling. In addition, this grade avoids the typical pitfalls of BON like moisture absorption and other converter handling problems.”
