Eastman now offers three outstanding Eastman™ Medical Polymers to help shape what’s next in rigid medical packaging.
Eastar™ copolyester 6763 has been the standard for clear rigid medical packaging for more than 20 years. It consistently delivers value by providing these advantages:
- Superior clarity – before and after sterilization
- Excellent puncture resistance and impact toughness
- Choice of sterilization method without post-radiation color shift
- Confidence-building functional and aesthetic package integrity
Eastman Tritan™ copolyester MP100 provides the advantages of Eastar™ copolyester 6763 with even better post-sterilization clarity and color. Plus, Tritan delivers higher heat resistance and greater inherent toughness needed for some rigid medical packaging applications.
- Greater toughness
- Provides durable protection of sterilized contents
- Allows redesign for lightweighting and downguaging; reduced secondary packaging
- Higher heat resistance
- Allows Higher sterilization chamber temperatures may allow faster ethylene oxide (EtO) cycle time and reduced risk of warping and sticking
- More rapid accelerated aging protocols for faster and more reliable shelf-life qualification; fewer go-to-market delays
- Slower aging process for greater confidence
Eastman Eastalite™ copolyester is an attractive alternative to opaque high-impact polystyrene (HIPS). Easier to process, it’s a safe and sustainable choice. Eastalite is a foamed copolyester resin that, when extruded into sheet, can be cut with minimal generation of particulates or angel hair—saving processing and inspection time, reducing waste and cleaning, and lowering costs.
- Color stability and functional integrity following sterilization*
- Limited compatibility in the recycling stream
- Cleaner cutting than HIPS
- Lightweighting opportunities
- Better hinge life
- Faster processing
- Reduced material waste
- Styrene-free alternative with no butadiene, BPA and BPS, PVC, halogens, or ortho-phthalates
*Suitable sterilization methods include EtO, gamma, e-beam, and gas plasma.
