The cold-resistant courier bag is designed for cold chain logistics and freezing regions. Made from specially formulated PE or co-extruded film, it stays flexible and impact-resistant at temperatures as low as -30°C to -50°C — no brittleness or stiffening.
Through anti-freeze additives and toughness modification, it maintains flexibility even at extreme lows. Unlike ordinary bags that stiffen around -10°C, this bag performs reliably at -30°C or below. Features thickened design, multi-layer co-extrusion, and low-temperature adhesive strips for secure sealing in freezing conditions.
Compared to traditional PE courier bags, the cold-resistant bag lowers the brittle point from -10°C ~ -15°C to -40°C ~ -50°C. Ideal for winter e-commerce logistics and cross-border shipping to Russia, Canada, and other cold-climate regions.
