Many cheap Lipton teas have this type of sachet. Using this plastic is a horrible trend and I'm not sure how it started. My worry was always more about leechi

  If I had to guess, the "plastic triangle" is a bit larger and would potentially allow larger tea-leaves to move more freely within the water and infuse better. The cheapest end of commercial tea bags are all basically tea powder, so they don't need the larger bags to infuse.

    That's possible, but I think you've already reached a point of diminishing returns with a standard teabag. They do have a more premium feel, so it's probably a combination of perceived quality and cost savings.
