Vacuum bags are specialized storage bags designed to remove air from the contents inside, creating a compact package. They are commonly used for storing clothing, bedding, and other soft items, helping to save space and protect against moisture, dust, and pests. The bags typically feature a one-way valve that allows air to be sucked out using a vacuum cleaner. These bags come in various sizes and styles, including zipper-seal and roll-up options. When the air is removed, the contents can be compressed to a fraction of their original size, making them ideal for organizing closets or packing for travel.
