Things You'll Need
Protective filler such as bubble wrap
Mailing liquids, creams or any items that can spill or leak can be a little tricky. That's not to say you can't send your sick grandma some homemade chicken soup. You just have to take a few precautions to make sure the item is as secure as possible as well as sealed inside.
Use a bigger box than you need.

Secure the tops of the containers. Before packing liquid items, tape the tops closed. Tape the lids both over the top and around the screw-on area.
Place containers in sealable plastic bags.
Fill the extra space with cushioning such as bubble wrap, packing peanuts, shredded paper and crumpled newspaper. Securely tape every seam on the box.
Label the package. When mailing liquids, the U.S. Postal Service requires you label and identify the contents on the outside of your package.
Don't drop your package in the mail. Go to the post office and hand it off to a clerk.
