To maintain product quality and prevent damage during storage and transportation, washing powder should be packed carefully using moisture-resistant, durable, and well-sealed materials. Below are the best practices:
1. Packaging Types & Materials
Packaging Type |
Material Used |
Recommended Usage |
Plastic Bags (PE, PP, or laminated film) |
Polyethylene (PE) or Polypropylene (PP) |
Small household packs (15g, 30g, 100g, 500g, 1kg) |
Kraft Paper Bags |
Multi-layer paper with inner PE coating |
Medium-sized packs (5kg, 10kg) for B2B distribution |
Woven PP Sacks |
Woven polypropylene with inner liner |
Bulk packaging (25kg, 50kg) for wholesale & industrial use |
Carton Boxes |
Corrugated cardboard with inner plastic lining |
Large shipments to protect against rough handling |
Plastic Buckets/Drums |
Hard plastic containers with airtight lids |
Industrial and commercial storage for damp environments |
2. Storage Guidelines for Washing Powder
Factor |
Best Practices |
Moisture & Humidity |
Store in a dry area with humidity below 50% to prevent caking. Use dehumidifiers if needed. |
Temperature |
Keep below 35°C (95°F) to maintain chemical stability. Avoid exposure to direct sunlight. |
Stacking |
Do not exceed 1.5 meters in stack height to avoid crushing lower packages. Use pallets for stability. |
Ventilation |
Ensure good airflow in storage areas to prevent moisture buildup. |
Avoid Contamination |
Keep away from strong-smelling chemicals (e.g., pesticides, oils) to prevent odor absorption. |
FIFO Method |
Follow First In, First Out (FIFO) to reduce the risk of expired stock. |
3. Safe Delivery & Transportation Tips
Aspect |
Best Practice |
Packaging Strength |
Use double-layer packaging (e.g., plastic + carton) for international shipping. |
Moisture Protection |
Shrink-wrap pallets or use moisture barrier liners inside containers. |
Shock Resistance |
Stack items properly to prevent tearing, leakage, or crushing during transit. |
Handling Labels |
Mark packages with "Keep Dry" & "Fragile - Handle with Care" instructions. |
Container Loading |
Use pallets for easy loading/unloading and to prevent crushing during stacking. |
Customs Compliance |
Ensure export packaging meets import regulations of destination countries (e.g., weight limits, eco-friendly material requirements). |
4. Best Practices for Export Shipments
- Small Shipments: Use carton boxes for extra protection when shipping via air or courier.
- Large Shipments: Use wooden pallets & stretch wrapping for bulk exports by sea.
- Bulk Containers: Consider moisture-proof bulk bags (FIBC) with inner liners for large industrial shipments.

Ensuring high-quality Cleaning Laundry Detergent Powder requires strict quality control at every stage, from raw material selection to final packaging.
1. Raw Material Quality Control
Key Aspect |
Quality Standards |
Testing Methods |
Surfactants (LAS, SLS, etc.) |
High active matter content (10-30%) |
Titration test, pH measurement |
Builders (STPP, Zeolite, Soda Ash) |
Proper ratio to enhance cleaning and prevent residue |
Solubility test, density test |
Optical Brighteners (Tinopal CBS-X, etc.) |
Must be stable and provide long-lasting whiteness |
UV light test |
Enzymes (Protease, Amylase, Lipase) |
High enzymatic activity for effective stain removal |
Enzyme activity test |
Moisture Content |
Should be ≤5% to prevent caking |
Moisture analyzer test |
Fragrance & Additives |
Stable, long-lasting scent without discoloration |
Smell test, stability testing |
2. In-Process Quality Control (During Production)
Key Aspect |
Quality Control Measures |
Batch Mixing |
Ensure uniform blending of ingredients to maintain consistent quality. |
Slurry Preparation |
Maintain correct temperature and viscosity to prevent clumping. |
Spray Drying |
Control moisture content (≤5%) to avoid caking or dust formation. |
Color Consistency |
Ensure uniform distribution of blue speckles in powder. |
Foam Control |
Adjust surfactant ratio to achieve high-foam (hand wash) or low-foam (machine wash) properties. |
Dust Control |
Implement dust collection systems to prevent contamination and loss of fine particles. |
3. Finished Product Testing & Inspection
Test |
Quality Standard |
Testing Method |
pH Level |
9 - 11 (Alkaline, safe for fabrics) |
pH meter test |
Dirt Removal Efficiency |
≥90% stain removal for common stains |
Standard washing test |
Foam Stability |
Consistent foaming based on application (high/low foam) |
Foam height test |
Solubility in Water |
Should dissolve within 30-60 seconds in cold and warm water |
Dissolution test |
Scent Retention |
Long-lasting fragrance (24-48 hours on fabric) |
Scent stability test |
Residue Test |
Minimal residue after washing (to avoid fabric damage) |
Visual residue check |
Shelf Life Stability |
Must remain effective for 2-3 years under proper storage |
Accelerated aging test |
4. Packaging & Storage Quality Control
Key Aspect |
Quality Control Measures |
Sealing Strength |
Check for airtight sealing to prevent moisture absorption. |
Leak & Burst Test |
Conduct drop tests and pressure tests on packaging to ensure durability. |
Weight Accuracy |
Each pack must contain the exact weight specified (±2% tolerance). |
Storage Conditions |
Store in a cool, dry place (<35°C, humidity <50%) to prevent caking. |
Palletization & Handling |
Use proper stacking methods to prevent crushing during storage and shipping. |
5. Final Shipment Quality Control
Quality Check |
Details |
Random Sampling Inspection |
Check 5-10% of the shipment for compliance before dispatch. |
Barcode & Label Accuracy |
Ensure correct branding, instructions, and batch numbers. |
Moisture Barrier Protection |
Use shrink-wrap and moisture-absorbing packets in bulk shipments. |
Transport Conditions |
Keep in dry, ventilated containers to prevent heat or humidity damage. |
Final Checklist Before Shipment
Raw materials meet all specifications
Production follows strict quality control standards
Finished product passes all tests (pH, foam, solubility, stain removal, etc.)
Packaging is sealed, durable, and correctly labeled
Storage and transportation conditions are optimal
