As a biochemical reagent or pharmaceutical raw material, L-Alanyl-L-cystine requires strict packaging and transportation conditions. The following details cover the selection of packaging materials and transportation requirements.
I. Packaging Requirements
1. Selection of Packaging Materials
Inner Packaging: Typically, pharmaceutical-grade polyethylene (PE) plastic bags or aluminum foil bags are used. Polyethylene plastic bags offer excellent flexibility, water resistance, and chemical stability, effectively preventing L-Alanyl-L-cystine from moisture absorption and external reactions. Aluminum foil bags, with superior barrier properties, block oxygen, moisture, and light, providing better protection for product quality. They are often used for products requiring high packaging standards.
Intermediate Packaging: Paper boxes or plastic bottles can be used. Paper boxes should have sufficient strength and compression resistance to protect the inner packaging from pressure damage. Plastic bottles, commonly made of high-density polyethylene (HDPE) or polypropylene (PP), offer good chemical resistance and sealing properties, ensuring stability during storage and transportation.
Outer Packaging: Generally, corrugated cardboard boxes or plastic turnover boxes are used. Corrugated cardboard boxes provide good cushioning and compression resistance, protecting the inner and intermediate packaging during transportation. Plastic turnover boxes, being more durable and reusable, are suitable for bulk transportation.
2. Packaging Labels
Basic Information: The packaging should clearly indicate the product name ("L-Alanyl-L-Cystine"), specifications, content, batch number, production date, and shelf life, ensuring users have accurate product information.
Warning Labels: Since L-Alanyl-L-cystine may have certain irritant effects or other potential risks, the packaging must include warnings according to relevant regulations, such as "Avoid contact with skin and eyes" and "Keep out of reach of children."
Transportation Labels: Labels indicating transportation precautions, such as "Fragile", "Keep Dry", and "Protect from Sunlight", should be included to ensure proper handling and storage during transportation.
II. Transportation Requirements
1. Temperature Control
Ambient Temperature Transport: If transported over short distances under suitable environmental conditions (typically 15°C-25°C), ambient temperature transport is acceptable. However, transportation during high-temperature periods should be avoided to prevent product degradation.
Cold Chain Transport: For long-distance transport or shipments during high-temperature seasons, cold chain transport is recommended, typically maintaining a temperature range of 2°C-8°C. Refrigerated trucks or insulated containers equipped with ice packs or cooling agents should be used to keep the product stable at low temperatures throughout transportation.
2. Humidity Control
L-Alanyl-L-cystine is hygroscopic, so strict humidity control is necessary during transportation. Desiccants, such as silica gel, should be placed inside the packaging to absorb moisture and prevent caking or degradation. Transportation vehicles and storage areas should remain dry and well-ventilated, with humidity levels controlled between 40%-60%.
3. Avoiding Vibration and Impact
During loading, unloading, and transportation, products should be handled with care to prevent severe vibrations or impacts that may damage the packaging. For glass bottle packaging, additional protection is required, such as foam padding or air cushions, to minimize the impact of vibrations.
4. Transportation Certification
Companies or individuals transporting L-Alanyl-L-cystine must possess the necessary qualifications and permits. Transport personnel should receive professional training to understand the product’s properties and handling precautions, ensuring safe and compliant transportation.
