I noticed a guest looking at it, and then saw that nobody had given the answer...is that OK?

I do that a lot. It is interesting to see what the quests are reading  and there are some great old topics out there that can be carried on and extrapolated from like the branches of a tree or a web or LOL Shall I go on! lol

Water's a tricky substance; it tends to get everywhere. If you want really waterproof, you have to go to a lot more trouble than a 'plastic bag'.
Potato crisps are stored in very sophisticated bags which include PTFE . They go 'off' very quickly in ordinary poly bags.

You are right, Andrew. But the crappy plastic bag/wrapper a chicken or other frozen bird comes in, are not really designed to hold the water, blood, gunge for any lenght of time.

This is why they use cheap plastic.

They are designed to get blood over the bags of flour in your shopping trolley.

I'm tempted to say no they are not waterproof 'cause they put airholes in them, but you're not talking about that type of bag.
I think all of the suggestions made can account for it. Condensation, poor quality plastic, possibly frozen stuff melting, also possibly other things in your fridge dripping on to it? Just a thought.

Excellent...thank you RHADE and WELCOME to the forum !!

You Know something interesting I have never had that problem with vacuum sealed bags. They are heavy duty plastic and heat sealed!

On a similar theme, I have recently noticed moisture inside an airtight plastic storage box in my fridge.

If you roast or cook anything in your microwave using a plastic bag specially
made for this cooking purposes then you'll get condensation, steam and the water
will run out of the bag after you have finished doing so.

Also, evaporation occurs, even at low temperatures.
