Best Practices For Storage And Handling Of Plastic Granules

To preserve material performance and operational efficiency, plastic granules must be stored and handled according to strict industry standards



Plastic granules are sensitive to environmental conditions and physical contamination, so following best practices from receipt to processing is critical



Begin by placing plastic granules in a climate-controlled, dust-free, and properly aired environment



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, or unstable polymer flow in high-precision manufacturing



Sealed, desiccant-lined containers paired with stable room temperatures (15–25°C) are ideal for preventing both moisture uptake and thermal stress



Clearly identify every bin or bag with material ID, lot code, receipt timestamp, and shelf-life cutoff



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



Keep different grades or colors of granules separated to prevent cross-contamination, which can ruin entire production runs



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



Handle bags gently to minimize particle breakage and prevent the release of fine plastic dust



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



Large-scale facilities should invest in sealed silos equipped with dehumidification and airflow regulation for extended storage



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



Clean storage surfaces frequently to prevent buildup of dust or residue from previous materials



Always follow the manufacturer’s recommendations for drying times and temperatures before processing



Visual dryness is not a reliable indicator; internal moisture must be extracted through controlled thermal treatment



Use calibrated drying equipment and monitor humidity levels in the drying chamber



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



Provide appropriate personal protective equipment and ensure good housekeeping practices



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



This data helps identify patterns, improve processes, and meet quality standards during audits or inspections



Adopting these protocols leads to lower scrap rates, enhanced part quality, prolonged resin viability, and a more secure, اکسیر پلیمر streamlined production environment
