That site is obviously highly skewed toward plastic. Look at these words:

Paper -

All cutting, printing, packaging, and shipping, requires additional time, labor, and energy, on top of the already exorbant amounts of capital, electricity, chemicals, and fossil fuels used.

Vs.

Plastic -

The oil drilling operation, itself, has become a rather small and sterile undertaking.

and

Plastic is, by comparison, efficient and low energy to produce, and, easily and efficiently recycled. Plastic reduces, recycles marvelously, and in that, is reused.

and

Plastic comes as a by-product of oil refining, and uses only 4% of the total worlds oil production.

And I don't know where they come up with this:

The electricity used from start to resin/raw material is mostly nuclear.

I highly doubt this is true, though I don't have time to research it right now, but I strongly question most of the statements and conclusions in this article.

The power used in the bag manufacturing, for the most part, comes from coal fire power plants. One interesting note is that approximately 50% of the electricity generated from coal burning power plants is not from coal at all, it is, in fact, wrought from the burning of old tires, they being made of rubber, which is plastic.
