In a recent package from amazon I noticed that the packaging was a little different. Until this package the plastic air filled wrap was made of #2 recyclable plastic. This was made of #4, recyclable and Biodegradable. The manufacturer is Intertape Polymer Group … read on for more … 
" … our corporate commitment … on reducing waste and any harmful environmental impact throughout the manufacturing process or footprint … we can’t eliminate all activities that affect the environment … we can focus on the activities that can reduce our environmental impact …"
"Lili … is a commitment shared by the leaders and employees of Intertape to continually look for opportunities to lower our environmental impact so sustainability is within reach. We invite you to do the same."
" … try this suggestion for lowering your impact … Lower your energy consumption and save money by replacing bulky computer monitors with a flat panel monitor. They use 1/3 of the electricity which is the equivalent to the savings of leaving a 50W bulb burning for one year. "

"The oxo-biodegradable air pillow film contains an additive that initiates chemical breakdown of the polymer chains much more quickly and completely than a standard film when in the presence of oxygen and heat or UV light … the molecular components can be consumed by micro-organisms … biodegradation leaves only water, carbon dioxide, biomass and small quantities of minerals that will be assimilated into the ecosystem."
"… one of the advantages of oxo-biodegradable films is the ease of recycling through mainstream recycling services. Unfortunately, not all products make it to recycling or even waste receptacles resulting in litter. An oxo-biodegradable air pillow that is discarded into the environment is much more likely to undergo the biodegradation process."
