Toray Plastics (America) has introduced its new suite of polyethylene terephthalate (PET) films that can be used in gamma irradiation sterilisation packaging applications.

Featuring three variants, Lumirror GA10, GA25, and GA66, the polyester film range offers improved retention of tensile properties, including tensile strength at break, Young’s modulus, and elongation break.

The films also provide optical properties, such as gloss, haze, and colour, for up to two years after initial radiation exposure by a Cobalt-60 irradiation processor.

Each of the GA films features different functionalities, with GA10 being a printable film, GA25 a heat sealable, while GA66 can be used as a mono web or in packaging laminations.

With better thermal and dimensional stability, the films can be used to supply various medical needs, such as instruments, syringes, implants, catheters, IV sets, surgical gloves, and gauze.
