A vacuum bag is a storage solution designed to remove air from its contents, typically clothing or bedding, to save space. It is made from durable plastic and features a one-way valve that allows air to be sucked out using a vacuum cleaner. This process compresses the items inside, making them easier to store in closets or under beds. These bags are popular for seasonal storage, travel, and organizing spaces. They help protect items from dust, moisture, and pests. Vacuum bags come in various sizes and can be reused multiple times, making them a practical choice for efficient storage solutions.
