Ziploc Freezer Quart Food Storage Bags, School Supplies, Stay Open Design, Grip 'n Seal Technology, Zipper, 100 Count

Ziplock is quality. Buy freezer type for heavier duty. I have no love for slider bags-the slide and top of the side seams like to fail. These are zipper fasten, line up the tracks, press together and run thumb and finger to the end. Airtight. These are also my favorite for making up an ice pack. Put cubes or cracked ice in baggie, add a little water to speed up the cooling, burp the air out as you seal. Turn 90 or 180 degrees and slide into another baggie. Burp the air as you seal. Put a washcloth or hand towel around the baggie and apply. You can freeze the unit again for reuse. I often cook large quantities and portion and freeze some for later. I also buy in bulk and break down large quantities to freeze for later. These bags work well for quantity and protection against freezer burn. I also use some for craft materials storage, and parts storage when repairing things. The last I knew, TSA will allow a maximum of 10 one-quart baggies per passenger. Feel free to use these for storing and organizing your things for travel, they do prevent a leak from getting everywhere. I also use several sizes of baggies to organize and keep my yarn and projects organized and clean. I cut flat spools from cereal boxes and wind smaller lengths to make neat, then store in quart baggies. A box of 100 means you have a good supply on hand. This is also an economical way to buy.
