I've really got into proper jobs lately I just find those seem to really work as they should smell amazing and I know they will still be up in the morning,
I have yellow banana ones, Camo brown black pepper + ones,beige devil's dung and cheese, and white scopex special dumbells, at the moment I favour banana and BP+ though,
Ziplock or plain freezer bags are perfect. I break mine down into 500gram or 1kg bags and store them like that in the freezer.
Something else that works is supermarket ice cream tubs. Makes a 'single use' plastic tub multiple use, and they will stack tidily in a chest freezer.
Just remember to eat the ice cream first and that once used triple chocolate ice tub is now fishmeal boilies...
Thinking about it, don't wash the tub after use and you have ice-cream glazed boilies!
Pretty much the same as Vik, I sometimes double bag to stop freezer burn but always add a drop of hydro to the bag before placing in the freezer, as they defrost the boilies draw the hydro in so your pumping out attraction from the off.
I order 200 press seal bags on eBay for just over a fiver. Big enough to take 2/3kg depending on bait size. I split in to 2kg normally. Handy grab bag in the morning for baiting up or when I go.
I add glug from frozen so they defrost and draw it in so I like to have excess room for air so I can shake them.
just make sure you squeeze all the air out the bags so you can store them using less space.
