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

Hygroscopic resins including nylon, PET, and PC are particularly vulnerable to moisture-induced degradation

Trace levels of water may cause surface blemishes, reduced mechanical strength, or erratic flow behavior during molding or extrusion processes

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

Each container must be marked with the resin type, production batch, incoming date, and recommended usage deadline

Clear labeling enables effective FIFO (first-in, first-out) practices and minimizes the risk of degraded material entering production

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

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

Conduct routine checks for rodent activity, اکسیر پلیمر water intrusion, or surface moisture buildup

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

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

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

Verify that drying systems are accurate and consistently maintain low humidity levels within the chamber

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

Plastic dust can be an inhalation hazard, and some materials may generate static electricity, which poses fire risks in certain environments

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

Keep detailed logs of environmental data, drying settings, and production anomalies for audit readiness

Historical records enable root cause analysis, process optimization, and compliance with ISO or industry-specific regulations

By implementing these best practices, companies can reduce waste, improve product consistency, extend material shelf life, and create a safer, more efficient operation
