Best for Snacks
Glad Double Lock Zipper Bags, $2.50 for 25 quart-size bags
The test: Store salty snacks in a cupboard for five days.
Why it won: You need a little elbow grease to open this bag’s tight seal, but it’s worth the effort: Pretzels and chips were still crispy and “decidedly fresher.” Also in gallon size.
To buy: At supermarkets.
