So i have a very heavy milk supply and ive been freezing a lot of my milk and i bought some bags to store my milk in but they leak from the top when i lay them flat and have been forced to freeze them standing so the bags are more bulky but i didnt want to waste the box i had just bought. now that the box is almost gone what bags should i buy that i can lay flat to freeze without having to worry about leaking? and preforably bags big enough i can put about 6-10oz at a time in if possible

**Side note**

the bags i had previously bought were store brand portion pack bags from winco
