I bought a lift-top coffee table from a big box store almost a decade ago. It’s entirely particle board and has seen better days cosmetically, but it’s probably my single favorite piece of furniture. It’s immensely practical for meals, using a laptop, or just bringing your remote/drink/whatever closer to your hand when laying down on the couch. I instinctively try to lift other people’s coffee tables when I visit, and am mildly annoyed when it doesn’t work…
for bread bags and similar, just twist it tightly closed and fold under to keep it from untwisting.
Twist ties don’t really seal it, they just keep it from untwisting (which is what seals it.)
