Heavy-duty bags designed for secure storage, organization, and easy labeling. Made from thick polyethylene, they provide added strength and puncture resistance, making them ideal for holding heavier or sharper items. The white write-on block allows for quick labeling with markers or pens, helping with identification and inventory control. Featuring a reliable zip-top closure, these bags can be opened and resealed multiple times while keeping contents clean, protected, and easily accessible.
