What is the effect of Moisture on Polymer Granules Exports?

In the plastic granules industry, the impact of moisture on polymer granules during cargo exports is a significant concern. This can affect both the quality of the polymers and the efficiency of the export process, leading to economic and operational challenges.

• 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.
• Contamination and Product Defects: Moisture can cause contamination within the polymer granules, affecting the consistency and purity of the product during cargo shipment. The presence of water vapor in the polymer during processing may also lead to unwanted reactions, such as hydrolysis, which can further degrade the material's integrity during export.

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.

Application of Cargo Desiccant Bags for Polymer Granules Shipment

Polymer granules are essential raw materials in the plastic industry, and absorb moisture during transit, which can lead to defects, degradation, and processing issues. Cargo desiccant bags are an effective solution to prevent these moisture-related problems.

• Moisture Control in Transit Environmental conditions such as temperature and humidity can fluctuate, creating a risk of moisture accumulation inside the container during polymer granule export. This excess moisture can be absorbed by the polymer granules, affecting their quality. Cargo desiccant bags absorb the moisture from the air, maintaining a dry environment and protecting the granules from damage during the shipping process.
• Preserving the Quality of Polymer Granules Polymer granules are sensitive to moisture, as the absorption of water can alter their physical and chemical properties. By using cargo desiccant bags, the moisture in the air inside the shipping container is controlled, helping to maintain the integrity of the granules. This ensures that the granules remain suitable for processing, and the finished plastic products meet the required specifications.
• Preventing Clumping and Stickiness Polymer granules that absorb moisture during shipment can become sticky or clumpy, making them difficult to process. This can cause problems during manufacturing, such as clogging machinery or creating uneven products. Cargo desiccant bags effectively prevent polymer granules from absorbing excess moisture, ensuring they remain free-flowing and easy to handle throughout the shipping process.
• 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.
