Prepare a plastic bottle, carefully cut off the mouth of the bottle, and make the edge as flat as possible, so it is safer to use.
Then put the endless snacks into the plastic bag. If the packaging bag itself is not too thick, you don't need to change the plastic bag. Go through the bottle mouth directly and cover the bottle cap to seal it!
You can cut a few more plastic bottle mouths for a rainy day. Besides filling endless snacks, you can also seal the seasonings in the kitchen!
