The plastic bags are probably polyethylene, which has a very low UV
resistance and left out in the sun will become brittle and crack in a very
short time. There are very few adhesives that will stick to polyethylene.
We used it to prevent epoxy from sticking to our counter tops in the lab.
You would be much better served to go ahead and buy a liner.

I am thinking about creating a bog pond, about 300 gallons, (maybe
just mosquito fish), lots of plants, Max about 9'' deep, wants to
attract wide animal or bird.
To save some money, I have a lot of very thick , big plastic bag
(5'x3'), can I use them as regular liner (them looks very tough)? (I
may have to stitch or glue those plastic bags to gather ).
Have anyone done that before?
please advice.
Thanks.
