It was another frustrating afternoon for the Seasiders, with their struggles in front of goal continuing.
On the flip side they are still yet to concede this season, with Olly Casey among the impressive performers at the back.
Shayne Lavery came close to opening the scoring against Orient after only three minutes, with his effort tipped over by the keeper.
Down the other end, Dan Grimshaw stopped a close-range header, while Joe Piggot fired over the bar on the rebound.
Blackpool took more control after the break, with Lavery hitting the post, after an initial effort from Albie Morgan was parried by Sam Howes.
Here is how the Seasiders performed:

8. Albie Morgan- 7
A solid performance from Morgan. The midfielder forced a couple of saves from Howes, with the second in particular really causing Orient some problems. Photo: CameraSport - Dave Howarth
9. Andy Lyons- 6
Like Hamilton, more is needed going forward from Lyons. Photo: CameraSport - Dave Howarth
10. Jake Beesley- 6.5
Beesley mainly had to work with half chances, including a ball over the top, which he couldn’t quite get enough on to beat the keeper. He also played a good through ball to Lavery in the early stages, but other than that there was nothing of note. Photo: CameraSport - Lee Parker
11. Shayne Lavery- 7
The striker had an early opportunity to open the scoring but saw his effort tipped over the bar by Sam Howes. He also came close at the beginning of the second half, with a quick-fire shot hitting the outside of the post. Photo: CameraSport - Lee Parker
