Technically How Do Green Bags Work?

Answer 1

The green bags are made out of a material called zeolite. The zeolite has a porous microstructure that allows it to trap different kinds of molecules. In the case of most produce, ethylene gas is emitted and stays stagnant near the surface of the fruit or vegetable. The ethylene gas is what causes produce to wilt and rot. The zeolite in the green bags captures the ethylene gas with in its microstructure so it can't harm the produce. Eventually, the zeolite becomes saturated with the ethylene gas and renders it ineffective. Another concern with green bags is that the produce must be completely dry before being placed in the green bags. This is because water molecules can also be captured by the zeolite, reducing the amount of open sites to capture the ethylene gas.
