What is the effect of Moisture on Polymer Granules Exports?

• Moisture Absorption: Polymer granules are susceptible to absorbing moisture from humid environments during cargo shipment. When exposed to moisture, the granules can become sticky, clumpy, or degrade in quality. This is especially concerning for hygroscopic polymers, which tend to absorb moisture even in low-humidity conditions.
• Degradation of Material Properties: The presence of moisture in polymer granules can significantly affect the material’s mechanical properties during export. Moisture absorption can lead to changes in the polymer's melt flow index, which directly impacts its processing characteristics during shipment. Additionally, polymers exposed to moisture may suffer from reduced tensile strength, brittleness, or even color degradation after molding or extrusion.
• Processing Problems: When polymer granules that have absorbed moisture are heated during processing (such as injection molding or extrusion), the moisture evaporates, causing bubbles, steam, and defects in the final product. This leads to imperfections such as surface pitting, voids, or even cracks. In severe cases, the material may fail to melt properly, leading to machine downtime and production delays.

Why Cargo Desiccant Bags Are a Smart Choice for Polymer Granules Shipment?

Polymer granules are often hygroscopic, meaning they have a natural tendency to absorb moisture from the air. This can lead to a range of issues, from changes in material properties to product defects during manufacturing. One of the most effective and cost-efficient solutions to mitigate these risks is the use of cargo desiccant bags.

Cargo desiccant bags offer significant advantages for the plastic granules industry by providing an effective, affordable, and simple solution to moisture-related challenges during shipment. By maintaining a dry environment, cargo desiccant bags help preserve the quality of polymer granules, reduce the risk of defects, and ensure smooth processing, Cargo desiccant bags are a smart choice for polymer granules shipment.

• Maintaining Compliance with Industry Standards Certain industries require strict moisture control during the shipment of polymer granules, particularly when dealing with food-grade or medical-grade plastic materials. By using cargo desiccant bags, manufacturers and exporters can ensure that the polymer granules meet industry-specific quality standards and regulatory requirements, reducing the risk of non-compliance during inspections.
• Sustainability and Eco-Friendly Options Cargo desiccant bags help maintain the quality of polymer granules while meeting environmental goals. Choosing cargo desiccant bags ensures that the shipment process aligns with sustainability practices without compromising the performance of moisture control.
