Ziploc bags are a staple in my home. It's soo handy for food storage, marinating, brining and packaging lunches for the family. It's zip seal prevents spillage and the sturdy bags don't break easily. Nowadays, it comes in all sizes with double zip seals or sliders.
One of their newer bags is the vacuum system that allows you to vacuum seal your food by manually operating a pump. Kind of like the vacuum sealer used in sous vide.
The brand has also branched out into plastic containers in all shapes and sizes using Smart Snap or Twist n Loc covers.
And a permium Versa Glass line of glass containers that can store, heat and serve. I know lots of people whether they live alone or in large families will love this for the convenience.
If you don't own any microwave steamware than the ziploc Zip n Steam is for you. Throw in vegetables or seafood and pop it into the microwave for a few minutes. The bag can be thrown away after use.
Ziploc also makes jumbo sized bags for non food items. Store art supplies, toys and even clothes in these big bags for storage.
