Six Reasons Why Poly Bags Are A Sound Choice For The Environment

poly-bag-1Energy required to manufacture plastic vs. paper

It takes more than four times as much energy to manufacture a paper bag as it does to manufacture a plastic bag. The primary reason for this is that it takes only one-eighth as much material to produce a plastic bag.



The use of these toxic chemicals in most kraft paper contributes to air pollution, acid rain and water pollution. Paper sacks generate 70% more air pollution and 50 times more water pollution than plastic bags.


The Landfill Crisis

Plastic film is estimated to account for less than 3% by volume of municipal landfills compared to 97% other materials. By weight, plastics account for only 7% of the U.S. landfills compared to 36% for paper.



It takes seven trucks to deliver the same quantity of paper bags contained in one truck of plastic bags.


Recycling, Reuse and Source Reduction

It takes 91% less energy to recycle a pound of plastic than it takes to recycle a pound of paper. Thinner, superior films has a significantly reduced the volume and weight of plastics in municipal landfills.



Special additives can be blended with polyethylene resin to make them “oxo-degradable,” so they degrade over a period of time when exposed to outdoor elements. They will not leave fragments, methane or harmful residues.
