Cut and sewn from aluminum-plastic or paper-aluminum composite substrates, these open-top bags feature a design that allows for convenient filling, eliminating the need for cumbersome bag-opening procedures. Combining the texture of paper with the barrier properties of aluminum foil, these bags are waterproof, moisture-resistant, light-blocking, and freshness-preserving, effectively preventing material oxidation and caking. The bag body is stiff, durable, and tear-resistant. Dimensions and lamination styles can be customized as needed, making them suitable for the repackaging and storage of pigments, flavorings, pharmaceutical excipients, and fine chemical raw materials.
