There are a few reasons why beer in plastic is only now being marketed.
One reason is that many plastics are permeable to oxygen. Special
plastics are used to exclude oxygen from traveling through the plastic
and I guess that soda was not as sensitive to oxygen degradation as
beers. Oxygen barrier plastics have been around for a number of years
but they are relatively new on the market.

A second reason would be tradition. It's difficult to change when the
equipment and process is all set up... and it's been that way for a
hundred years and and we've always done it this way...don't fix it if it
ain't broke.

And a third reason I can think of is the economic cost to change over to
a new process/system.
