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 in closets or during travel. The bags work by sealing tightly and using a vacuum cleaner or a manual pump to extract air, which reduces the volume of the items. These bags are often made from durable plastic materials that protect against moisture, dust, and pests. Many vacuum bags come in various sizes and can be reused multiple times, making them a practical solution for organizing and preserving belongings.
