Ziplock bags are resealable plastic bags that are commonly used for storing food and other items. They come in various sizes and are made from durable, flexible plastic. The bags feature a simple sliding mechanism that allows users to seal and unseal them easily, keeping contents fresh and protected from air and moisture. These bags are popular for organizing items, packing lunches, and preserving leftovers. They are also useful for travel, as they can hold toiletries or snacks. Ziplock bags are often reusable, making them an eco-friendly option when cleaned properly after use.
