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:

Weir looked bright in the early stages, providing energy both on and off the ball. Throughout the entire match there were snippets of what the midfielder can offer, before coming off just after the hour mark. Photo: CameraSport - Lee Parker
