As you prepare to pack and ship fragile gifts to your loved ones for the holidays, here's a sustainable alternative to bubble wrap and foam peanuts; popcorn! Economical, sustainable, and efficient, plain popcorn provides just as much cushion as plastic packaging materials do.Even better: transport emissions will also be reduced, since popcorn is 60% lighter than paper. So go ahead and pop up some air-popped (you don't want grease getting on the packaged items!) unsalted, non-flavored plain popcorn and fill your holiday shipping packages with it. Drop a note in the box explaining to the recipients the benefits of popcorn packaging, and encourage them to scatter it outside for the birds and squirrels.
