That's an excellent question! Dealing with a trash bag that constantly slips down into a tall, sleek kitchen bin is a universal urban frustration. You take the bag out, and half the garbage is scattered inside the can. Luckily, there are some brilliantly simple solutions to this common problem.
First, the Bungee Cord Method is a favorite for its effectiveness. Simply place your bag in the can, pull the edges over the rim, and then stretch a single bungee cord around the circumference, over the bag's lip. This creates downward pressure that holds the bag firmly in place, even when you're tossing in heavier items.
If you don't have a bungee cord, look no further than your office supplies. Large binder clips are a perfect hack. Clip several of them evenly around the rim, pinning the trash bag liner securely between the clip and the bin's edge. They are inexpensive, easy to remove, and surprisingly strong.
For a more built-in solution, consider using bin liners with drawstrings. While not all tall bins are compatible, if yours has a wide enough opening, you can tie the drawstring tightly and then tuck the excess string down between the bag and the bin wall. This creates a anchor point that resists slipping.
Finally, a little double-sided tape can work wonders. Apply a few strips of heavy-duty double-sided tape to the outer rim of your bin before you place the bag. Press the plastic bag liner firmly onto the tape. This creates a strong, temporary bond that will keep your bag right where you want it, making trash duty a much cleaner affair.
