L-Proline requires protection against physical damage, chemical contamination, and property changes during transportation to ensure safe and stable delivery. Below are the key transportation guidelines:
1. Packaging Requirements
Basic Packaging
Inner Packaging: Use food-grade/pharmaceutical-grade polyethylene plastic bags or aluminum foil bags for airtight sealing to prevent moisture absorption and oxidation.
Outer Packaging:
Industrial Grade: Cardboard drums, plastic barrels, or woven bags with inner plastic linings to ensure sturdiness and pressure resistance.
Food/Pharmaceutical Grade: Reinforced cartons or wooden boxes compliant with standards such as General Technical Conditions for Transport Packaging of Dangerous Goods (GB 12463).
Special Scenarios: For small quantities or cold-chain transport, use insulated boxes with ice packs (for refrigeration needs) or vacuum packaging to minimize environmental impact.
Labeling: Clearly mark product name, batch number, net weight, moisture-proof, light-proof, upright handling symbols, and emergency contact information.
2. Transportation Environment Control
Temperature and Humidity
Routine Transport: Avoid high temperatures (>30°C) and direct sunlight. Ensure good ventilation in transport vehicles; use refrigerated trucks or sunshade measures in summer.
Humidity Management: Keep transport tools dry. Use waterproof tarps during rain to prevent packaging damage and water ingress.
Avoid Mixed Transport and Contamination
Forbidden Mixtures: Keep away from strong acids, alkalis, oxidizers, and toxic/hazardous materials (e.g., pesticides, chemical raw materials) to prevent chemical reactions.
Dedicated Transport for Food/Pharmaceutical Grades: Use specialized vehicles and avoid co-loading with fresh produce, oils, or fats to prevent odor transfer or microbial contamination.
3. Selection of Transport Vehicles
Road Transport
Prioritize enclosed trucks with clean, dry, and odor-free compartments. For long-distance trips, regularly inspect packaging integrity to prevent damage from 颠簸.
Rail/Sea Transport
Rail: Use covered freight cars (avoid open-air transport).
Sea: Ship in containers to protect against seawater corrosion and moisture. Pre-clean and dry containers; add desiccants if necessary to maintain internal humidity ≤60%.
Air Transport
Comply with air freight regulations, using rigid packaging to prevent crushing. For cold-chain needs, declare in advance and meet the airline’s temperature control requirements.
4. Safety and Compliance
Regulatory Adherence
As a food additive or pharmaceutical raw material, comply with the Food Additive Safety Management Regulations, Good Supply Practice (GSP), and local transport regulations (e.g., International Maritime Dangerous Goods (IMDG) Code for international shipments).
Provide an MSDS (Material Safety Data Sheet) for exports, detailing physicochemical properties and emergency procedures.
Emergency Handling
In case of packaging damage or leakage, immediately collect spills with dry tools, avoid water contact, and cover contaminated areas with inert materials (e.g., sand).
Operators must wear gloves and masks to avoid direct skin contact or dust inhalation; rinse with water immediately if exposed.
5. Delivery and Inspection
Arrival Inspection: Recipients should verify packaging integrity, label clarity, weight, and conduct random sampling to check for caking, deliquescence, or off-odors.
Record Keeping: Archive temperature logs (if applicable), transport documents, and quality inspection reports for traceability in case of quality issues.
Conclusion: The key to safe L-proline transportation lies in airtight packaging, controlled temperature/humidity, and strict compliance with regulations. By selecting appropriate packaging materials, transport modes, and minimizing contamination risks, L-proline can maintain its stability and meet quality requirements across food, pharmaceutical, and industrial applications.
