Critical Protocols for Plastic Granule Storage and Handling

Proper storage and handling of plastic granules are essential to maintain material quality, ensure worker safety, and avoid production issues

Plastic pellets readily absorb moisture and attract particulates, making adherence to standardized procedures from the moment they arrive until they enter the machine absolutely vital

Ensure storage locations are free from moisture, debris, and airborne contaminants

Moisture is one of the biggest threats to many types of plastic, especially hygroscopic materials like nylon, PET, and polycarbonate

Minimal moisture ingress can result in visual flaws, structural weaknesses, تولید کننده کامپاند پلیمری or unstable polymer flow in high-precision manufacturing

Use sealed containers or bags with desiccant packs when possible, and keep storage areas at a consistent temperature between 15 and 25 degrees Celsius to prevent thermal degradation

Label all containers clearly with the material type, batch number, date of receipt, and expiration or use-by date

This helps with inventory management and ensures that older stock is used first to avoid material aging

Store distinct resin types and pigmented batches in isolated areas to avoid accidental mixing that could compromise product quality

When handling granules, use clean tools and gloves to avoid introducing dirt, oils, or other contaminants

Avoid dragging or dumping bags, as this can cause dust generation and physical damage to the granules

Use enclosed transfer systems or covered chutes to reduce exposure to ambient air during material movement

For long-term storage, consider using silos or bulk bins with moisture control systems, especially for high-volume operations

Schedule weekly inspections to detect infestations, structural leaks, or dew formation that could compromise material integrity

Maintain a strict cleaning schedule to avoid cross-contamination from prior resin types or debris

Prior to feeding into machinery, adhere strictly to the resin supplier’s specified drying protocols and thermal parameters

Granules may look dry on the surface but still contain harmful levels of trapped water

Ensure drying ovens are regularly calibrated and equipped with real-time dew point sensors

Train all personnel involved in handling granules on proper procedures and safety protocols

Inhaling fine plastic particles can cause respiratory irritation, while static discharge from certain resins may ignite flammable atmospheres

Equip workers with PPE and maintain organized, debris-free workspaces to reduce exposure and fire risks

Finally, maintain accurate records of storage conditions, drying parameters, and any issues encountered

Consistent documentation strengthens traceability and demonstrates adherence to quality management systems

Following these guidelines delivers measurable gains in yield, reliability, safety, and overall operational excellence
