Shelf-stable entrees: General food USA creates the first prepared shelf-stable entrees with over one year shelf life.This achievement enabled consumers to transition from using metal cans to plastic containers.

Aseptic pouches: Companies move from the rigid plastic containers to flexible, aseptic pouches. The food in these pouches are heat-treated to protect from microorganisms,enabling products(sauces,milk,tuna) to be shelf-stable and have extended shelf lives of up to 18 months.

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.
