Shareable hot-fill PET: Plastipak develops technology to make hot-fill PET bottles even lighter and able to be shaped into various designs on the production line.

Insulating Trays: MicroGREEN polymers develops a micro cellular plastics process that uses non-reacting CO2 gas to make the lighter weight trays that are also inherently insulating.These trays can be handled right out of the microwave without any burns or pain.

Probiopak: Hidden beneficial bacteria is used in the packaging to protect food and cosmetics.
