Researchers from the Good Housekeeping Institute tested 32 different storage containers. They wanted to know which ones did best keeping the air out, preventing food from drying out and picking up odors from other items. It turns out that in glass containers came out on top. "Glass is the most airtight container because it keeps air from coming in through the sides. It's not porous like plastic," said Good Housekeeping's Sharon Franke.

The testers chose "The Napware Glasslock" as the best glass container tested. It locks the freshness in place and proved the most leak-proof. Researchers however deducted points because the lids tended to warp in the dishwasher.

"Our advice to consumers is that they hand wash any plastic pieces that can warp in the dishwasher," said Good Housekeeping's Sharon Franke.

Scoring well in the plastic container category was the "Rubbermaid Lock-Its." testers liked that it was the only one that didn't break when drop tested with a frozen load. The lids also snapped onto the bottom of the container -- making it difficult to lose.

Disposable storage containers like Ziploc and Gladware tested ok in the Good Housekeeping test. But once they start to stain or damage, its best just to toss them away.

If you're looking for something to reseal dry foods the testers like the "Banana Seal by Seal-A-Bag."
