Maintaining a temperature-controlled environment for hot melt adhesives from factory to customer is crucial for preserving product quality in frigid climates. This requires a comprehensive strategy covering packaging, transport, and storage.

1. Packaging Upgrade: Creating a Mobile "Insulated Chamber"

• Thermal Insulation: Lining standard cartons with insulating materials (e.g., foam padding, insulating wool) slows the transfer of external cold into the box, providing a short-term buffer for the products.

• Moisture Barrier: Significant temperature differences between indoors and outdoors in cold regions easily cause condensation. It is essential to use moisture-proof sealed inner bags (e.g., aluminum composite bags) to prevent moisture absorption, especially for moisture-sensitive PUR.

• Impact-Resistant Design: Reinforce the compression and shock resistance of outer packaging to withstand the bumps and impacts during transport that could affect adhesives made brittle by the cold.

2. Transport Solution Optimization: Giving Logistics a "Temperature-Controlled Lifeline"

• Temperature-Controlled Transport: When the ambient temperature is consistently below 5°C, especially when there is a risk of freezing, the most reliable solution is to use temperature-controlled containers or trucks with heating capabilities, ensuring the cargo space temperature always remains within a safe range (e.g., >5°C).

• Indoor Transfer/Staging: In logistics planning, it is crucial to avoid leaving goods in open areas for extended periods during times of extreme cold, such as at night or in the early morning. All transfer points should be arranged in covered docks or indoor warehouses.

• Information Visualization: Affix clear labels such as "Keep from Freezing," "Keep Dry," and "Temperature Sensitive" on packages to remind handlers at all stages of the logistics chain to take necessary protective measures.

3. Warehouse Management: Establishing a "Warm Outpost"

• Setup of a Pre-warming Zone: Establish a temperature-controlled pre-warming zone (>15°C) near the receiving area. Upon arrival, goods should not be moved directly into a cold storage warehouse but should be allowed to sit in the pre-warming zone for 24-48 hours. This allows the adhesive to gradually return to room temperature from the inside out, preventing condensation caused by instantaneous temperature differences.

• Strict Ground Isolation: Goods must be placed on pallets and strictly prohibited from direct contact with the cold floor to minimize localized supercooling caused by heat conduction.
