I am seeing lots of problems with your argument here:

  * One, the amount of carbon that get wasted if that sandwich goes bad is immense compared to the small amount of carbon it takes to make the plastic.
  * Two, in places with decent waste management, what is wrong with the plastic sitting in a landfill.
  * Three, assuming you are still going to protect food items, the alternatives are all heavier materials that will increase transportation costs and pollution.
