A vacuum bag is a flexible packaging container that can expel internal air through an air extraction device to form and maintain a vacuum environment. Its core function is to isolate air, moisture, and external contaminants, achieving sealed preservation of items, moisture and rust prevention, or assisting in industrial processes (such as composite material molding). It is widely used in scenarios such as food storage, industrial packaging, medical sterilization, and composite material manufacturing. It is completely different from wood substitutes (composite materials focusing on structural replacement) and belongs to "functional packaging or process auxiliary tools."
Performance, tolerances and compliance are configuration-dependent and confirmed in the commercial offer.
