Two points that is. First, we got this lettuce in our Bread Riot basket three weeks ago. The lettuce is STILL extra crunchy and fresh (these photos were take on 2/3 and the baskets were 1/14...WOW!). I'm not sure if that is indicative of how fresh picked it was, or how it was kept.
Which was in this plastic container, second. It wasn't all "misted" by grocery store sprinkler systems, and it was in an airtight package.
Looks like a regular take out box, doesn't it?
Most household recycling programs don't allow number 7 plastics. Do you know what the numbers in the little recycle symbol mean? (via http://www.guvswd.org/symbols)

Other, huh? Well good thing this box had more information describing itself.
PLA stands for Poly Lactic Acid and is the chemical name of a plastic made from corn, an annually renewable resource. The look and act just like regular take out boxes, but at the end of use, PLA based products can be recycled or composted under commercial composting conditions 90% within 60 days and the balance within 90 days.
I'm not sure how much regular clam shell containers cost food service professionals, but I found cases of 250 PLAstic clam shells for $65. That seems like a very reasonable cost to avoid petroleum based plastics.
