The paper packaging industry—including paper boxes, paper rolls, paper bags, paper-laminated bags, and paper-laminated rolls—plays a crucial role in international logistics. Their recyclability, cost-effectiveness, light weight, and adaptability to various product types make them a preferred choice across industries such as food, consumer goods, electronics, and industrial raw materials.
During containerized export shipments, these paper-based materials are frequently exposed to fluctuating humidity levels, condensation, and direct water ingress. Unlike plastic or metal packaging, paper is a hygroscopic material, meaning it naturally absorbs moisture from its surroundings. This characteristic, while useful for biodegradability, becomes a liability in oceanic and long-haul transportation environments.
Paper-based packaging remains a cornerstone of international trade, offering a sustainable, lightweight, and cost-effective solution for protecting and presenting goods. Products such as paper boxes, paper rolls, paper bags, paper-laminated bags, and paper-laminated rolls are widely used across multiple industries for export packaging.
Despite their versatility, paper packaging materials are vulnerable to moisture exposure, especially during international shipments where environmental conditions are unpredictable. Prolonged contact with humidity, condensation, or water vapor can cause irreversible damage, affecting both the functionality and appearance of the packaging. Understanding these moisture-related effects is essential for ensuring product protection, customer satisfaction, and supply chain integrity.
Moisture Protection
Paper products such as boxes, rolls, and laminated bags are highly susceptible to humidity and condensation during storage or shipment. Silica gel and activated clay efficiently absorb excess moisture from the air, preventing:
Preserves Packaging Quality
Moisture can compromise the appearance, strength, and usability of paper-based packaging. Using desiccants ensures:
Compliance with Export Standards
International shipments often require adherence to humidity control regulations.
Eco-Friendly and Non-Toxic Options
Activated clay is a natural, biodegradable, and cost-effective desiccant. Activated clay desiccants for paper packaging exporters offer an eco-friendly moisture control solution. Silica gel is chemically stable and available in indicating or non-indicating forms.
Efficient During Long-Distance Shipping
Paper packaging is often exported in bulk containers over long sea or land routes. Silica gel and activated clay:
Both silica gel and activated clay are hygroscopic materials, meaning they naturally attract and trap water vapor from the air inside packaging or containers. This significantly reduces relative humidity (RH) inside shipping containers, helping to prevent condensation ("container rain"), surface moisture, and mold formation.
Available in a range of sizes (from 200 g to 2 kg or more), these cargo desiccant bags for paper product container shipping are typically hung on container walls or placed between pallets, depending on cargo layout and volume.
Container Cargo Adsorbent is a unique product designed specifically for shipping & transportation industry.
