Green Bags work well as expected to prevent ripening; why you can't expect them to kill molds and funguses.
They do what they say they do.  They have a finite lifetime as the absorbant material in the plastic is used up.  I should like to comment on the negative reviews that state that these bags are terrible because they do not stop mold.  These comments are based on a misapprehension of the action and purpose of the bags.  The green bags have a Zeolite clay embedded in the plastic.  The plastic, Polyethylene, is in fact, relatively porous to atmospheric and other gases.  The simple gas, ethylene, (C2H4) is a plant hormone and is given off by fruits and vegetables and this accelerates their ripening process.  The absorption of the ethylene by the clay, slows this ripening process down greatly, and thus improves the storage life of the produce significantly.  The Zeolite is NOT an antifungal, so will not kill mold.  [You and mold are both in the same Family of living things, called Eukariots, vs the bacteria (Prokariots).  Agents that kill mold can kill you, so the idea of produce bags with an antifungal is really a bad idea.  To reduce mold growth, make sure that all produce and their storage containers are very dry.  Keep refrigerator doors open as little as possible.  And never, never, never, try to salvage bread, fruits, or vegetables that are already showing any signs of mold.  Funguses release BILLIONS of spores from a single spot on a slice of bread.  Deposit moldy produce or bread containers UNOPENED into the trash bin.
