Storing cat food in plastic storage containers

I have a big yellow plastic storage container I bought from Walmart to keep the cat and dog food in since my cats LOVE to tear open the bags I buy. I buy 10kg bags at a time so it's perfect to store in one of these containers. My question is, is it possible for the plastic to damage the food in any way? Make it go bad? Usually a 10kg bag lasts about 4-5 weeks but now I have 15 kgs in there now so itll last about 6-7 weeks. Is it ok to store it in there for that long?
Im sure some people here do the same thing, so I figured I would ask.

I use a big plastic container. Just be sure to wash it out each time you fill it because the oils that collect at the bottom can go rancid.

I have a couple plastic pet food containers with an airtight seal around the top. If I dump the food in, rather than leave it in the bag, then I wash it out between new bags.

I also use plastic bins because my cats like to chew on the bags. If the bag is small enough, I just drop the entire bag in the bin. If I have to empty the food in the bin, I clean out the bins on a regular basis. Buy 2 bins so that you can rotate them as you clean them.

Honestly, I use and old (washed out) 35lb. kitty litter pail. It's so much cheaper to buy the big bags of food but to leave it in the bag it either goes bad or the cats thinks it's a help yourself situation. And this way I can replace it every so often as I buy new tubs of litter too.

I do the same deal as leave the food in the bag, clip the top shut, and put the entire bag into the plastic container - it holds the medium size Nutro bag. I figure I'm getting pretty air-tight storage, without a lot of possible plastic exposure. Also, my boy will eat through the bags, if he can get the closet door open, and he has.

You do know that all pet food bags are lined with plastic, right? The exception being poly-woven bags because they are plastic.

Just another reason to make sure we keep dry pet foods put up. Were a pet chew through the bag they'd be very much at risk for eating some of that plastic lining because it would have a bit of tallow on it making it smell like the rest of the food.

I use an air tight container and just dump the food in. It's also important that food be stored in a cool area, as well. Also, it you actually dump the food into the container, make sure it is food grade. I'm not sure if litter pails are.

I put my food in bins as well (dog, cat, and my rat food mix), but I keep it IN the bag, and just put it in the containers.

I keep mine in a vacuum sealed plastic container (it has the pump on the top), so it keeps the freshness...
I would put one bag at a time though, as the store sealed bags will keep the food the freshest...
