On January 31st, Constar International, headquartered in Philadelphia, announced that it has developed a new type of material that, when mixed with single-layer PET, can provide products with oxygen protection, anti-corruption, and deterioration protection. This material has been approved by the FDA and is currently limited to packaging ketchup.
Constar's product, DiamondClear, uses an oxygen barrier to chemically block oxygen molecules to minimize the amount of oxygen permeation, making the package look extremely transparent.
DiamondClear materials are mixed at the preform injection molding stage. This technology is compatible with one-step and two-step injection stretch blow molding methods, eliminating the need to purchase expensive co-injection equipment to produce multilayer barrier systems.
The FDA now only allows DiamondClear to package tomato sauce, and Constar wants DiamondClear to be widely used for packaging other foods.
