Is there a way to seal a hole in plastic?

HDPE?
you can plastic weld it pretty easily... harbor frieght has a tool for around 70 bucks i think?
you can also cut threads into the hole and plug it if the plastic is deep enough.
you could also seal it with any number of sealants... urethanes, epoxies, RTV maby... epoxy plumbing putty?
you could even install a bulkhead through the holes and just seal the bulkhead?
there is a shit load of ways to deal with this.

Sounds like NAPA's repair epoxy for resin panels on many car models.
It consists of a set of paired syringes with a mixing stinger about six inches long that can be replaced.
Push the plunger and apply same as caulk.
I sealed copper tubing through the bottom of a five gallon polycarbonate jug eight years ago, still solid without leaks. The Hexane/dry ice mix put the solution at -120 F for condensing Butane and the summer sun put it at +100 F between runs. No problem.
Made for body panels on cars and vans, it is tough. The $70 price tag means you have to really need something that strong.
no its a real plastic welder. basically a hot air gun with a tiny nozzle.
you melt a bit of the base material, and cram in plastic rod to join materials.
the harbor frieght one is supposed to be decent provided you dont abuse it. they dont make a speed tip for it though so you cant use it much beyond car shit.
J.B. Weld and Silicone are toxic (or at least not non-toxic), as far as I've found so I'm not taking the risk. I have a very strong silicone adhesive but it doesn't adhere to plastic.
Aquarium silicone only seems to work for glass, or at least I've only found ones that do.
Hot glue works! ..but it comes off after about two weeks, so not useful.
The only thing I've found that is non-toxic is Gorilla PVC Cement.. but I can't find it near me and I don't want to wait ordering it.
Meanwhile, I've decided to drill the drainage hole around the middle of the container, since the holes are slightly above the middle. This basically changes the 65L container to 30L but it's good enough for now.

lol unless its pvc, pvc cement wont do shit.
if you want non toxic... weld it.
